final rationale
Mean of 5 draws (0.25, 0.26, 0.30, 0.30, 0.28). (0) Nothing is resolved yet. The City of Toronto elections page shows only logistics, and election day is October 26, 2026. Bradford would have to outpoll Olivia Chow on that day.
(a) That leaves about 18 days. Advance voting is already under way (Oct 6–11).
(b) If nothing changes, Chow wins. Every public poll has her ahead: Nanos about 52–43, Liaison 48–40, Canada Pulse 51–34, Forum 46–42. Toronto has not defeated a sitting mayor seeking re-election since amalgamation.
(c) NO scenario: Chow holds a 5–10 point lead, and Chris Alexander's roughly 4–9% splits or stays home, as Tumilty suggests. Chow's dominance in Toronto-East York and her lead in Scarborough carry her through.
(d) YES scenario: the 12–22% undecided bloc breaks toward 'time for change.' Bradford's money and endorsements (Liberal MPs, Geddy Lee, Godfrey) pull ahead in turnout in Etobicoke and North York. A typical municipal polling miss, which City Hall Watcher says dominates its error budget, closes the 4–9 point gap.
The market sits at 30%, up 18.5 points in a week, which looks like it is pricing Alexander's exit and the tighter Forum poll. The City Hall Watcher model, built on 15 polls, gives Chow about 70%, with Bradford ahead by 2+ points in only 26% of simulations. Adding the incumbency base rate and the absence of any poll showing Bradford leading, I shade slightly below the market to about 25%.

This is a Polymarket question, so polymarket_direct is the price anchor. Kalshi may list the same Toronto mayoral race, which would give an independent crowd price. The Wikipedia page for the 2026 election should have the candidate list and the polling table, and resolution_source should point at the City of Toronto election results.

Research loops, bottom lines
- current state: With the field now consolidated to a two-way Chow-vs-Bradford race after Alexander's Oct. 6 withdrawal, every published poll from late September through early October 2026 (Liaison Strategies, Nanos, Forum Research) shows incumbent Olivia Chow leading Bradford by roughly 4-10 points among decided voters, and an aggregated forecast model puts Chow's win probability at about 70% versus Bradford at roughly 26-30%, making Bradford the clear underdog heading into the Oct. 26 election.
- base rate: Every public poll throughout the campaign (Liaison Strategies, Nanos, Canada Pulse Insights) has shown incumbent Olivia Chow leading challenger Brad Bradford by roughly 6–17 points, a gap that narrowed somewhat but persisted even after third-place Chris Alexander's withdrawal consolidated the "change" vote behind Bradford. Toronto's historical base rate strongly favors sitting mayors who seek re-election (Miller, Tory all won re-election when running again), and Bradford's own prior mayoral run
- yes case: Bradford's path to YES runs through his demonstrated fundraising edge, broad elite/cross-partisan endorsements (Liberal MPs, Geddy Lee, veteran councillors, Paul Godfrey), his real regional strength in Etobicoke and competitiveness in Scarborough/North York, and a sizable (12–22%) undecided/persuadable bloc plus majority "time for a new mayor" sentiment in at least one poll — all of which the City Hall Watcher model itself still credits with roughly a one-in-four-to-three-in-ten chance of flippi
- no case: Every independent structural indicator available as of Oct. 8 — the aggregator model's win probability, institutional labour endorsements, the walked-back Ford signal, intra-ward opposition to Bradford, and the absence of any turnout or momentum data favoring him since Alexander's withdrawal — points to continuity (a Chow win) rather than change, reinforcing the case that Bradford fails to win and the market resolves NO.

- [2026-10-06] Chris Alexander dropped out of the race after the poll showed him far behind, saying
"Chris Alexander realizes no 'path to success,' drops out of Toronto mayoral race."
Because the withdrawal deadline (Aug. 21) had passed, his name remains on the ballot but he is suspending his campaign and not endorsing anyone. (https://www.cp24.com/gta-elections-2026/2026/10/06/chris-alexander-drops-out-of-race-to-become-torontos-next-mayor/)

BOTTOM LINE: With the field now consolidated to a two-way Chow-vs-Bradford race after Alexander's Oct. 6 withdrawal, every published poll from late September through early October 2026 (Liaison Strategies, Nanos, Forum Research) shows incumbent Olivia Chow leading Bradford by roughly 4-10 points among decided voters, and an aggregated forecast model puts Chow's win probability at about 70% versus Bradford at roughly 26-30%, making Bradford the clear underdog heading into the Oct. 26 election.
NOT FOUND: No poll or report as of 2026-10-08 shows Bradford leading Chow; no indication of any late endorsement, scandal, or event that has shifted momentum decisively toward Bradford since Alexander's withdrawal.
report: base rate
- [2026-10-06] Chris Alexander dropped out of the race on the first day of advance voting;
his withdrawal appeared to clear the way for a head-to-head race between leading contenders Olivia Chow and Brad Bradford
. A same-day
Nanos Research survey showed Chow at 52.4 per cent among decided voters, Bradford at 42.6, and four per cent for Alexander
. (https://www.theglobeandmail.com/canada/article-chris-alexander-toronto-mayor-race/)
- [2026-10-06] A Liaison Strategies poll the same day found
Alexander at a distant third place with only 9 per cent support, while Chow came out on top with 48 per cent support among decided and leaning voters and Bradford followed up with 40 per cent

- [2026-09-~] A prior Liaison poll showed the race narrowing:
47% would vote Chow vs 40% Bradford, versus a Sept. 9 Liaison poll where Chow stood at 50% and Bradford at 39%
. (https://www.cbc.ca/news/canada/toronto/liaison-poll-chow-leading-race-tightens-9.7353690)
- [2026-10-~] A Canada Pulse Insights poll for Rogers CityNews found
Chow at 51 per cent among decided voters, 17 points ahead of Bradford at 34 per cent, with Alexander at nine per cent and 20 per cent undecided
(taken before Alexander's withdrawal). (https://nowtoronto.com/news/toronto-election-2026-olivia-chow-leads-brad-bradford-by-17-points-poll/)
- [2003-11-10 to 2026] Base rate for Toronto incumbent mayors seeking re-election is historically strong:
David Miller was re-elected in November 2006 with nearly 60% of the popular vote
, and
John Tory secured a third term, winning a landslide victory in the October 2022 election
. Toronto has not defeated a sitting mayor seeking re-election since amalgamation in 1997 (Lastman, Miller and Tory all won re-election when they ran; Ford and Chow are the only incumbents who did not seek/complete another term for other reasons).
- [2023-06-26] Bradford's own track record as a mayoral candidate is weak: in the 2023 by-election (the one prior contest in this reference class),
he previously contested the 2023 mayoral by-election, placing eighth
out of over 100 candidates, far behind winner Chow.
- [2026-~] Wikipedia's current election summary confirms the contest remains framed as a three-candidate (now effectively two-candidate) race:
Olivia Chow formally declared her candidacy and is being challenged by Toronto City Councillor Brad Bradford and former federal Conservative cabinet minister Chris Alexander
(Alexander has since withdrawn). (https://en.wikipedia.org/wiki/2026_Toronto_municipal_election)
- [2026-10-07] Campaign veteran commentary suggests Alexander's departure does not clearly help Bradford:
Andrew Tumilty, who managed John Tory's successful 2018 and 2022 campaigns, noted polling indicated Alexander drew support from voters unhappy with both front-runners, suggesting those votes will not migrate en masse to Bradford
. (https://www.newsy-today.com/chris-alexander-drops-out-of-toronto-mayoral-election-race/)
- [2026-10-~] 53 candidates filed for mayor (52 after Alexander's withdrawal), but
the top three candidates in the polls, Olivia Chow, Brad Bradford, and Chris Alexander, all offer very different visions of the city
, with all other candidates polling negligibly. (https://thelocal.to/toronto-mayoral-candidates-2026/)
BOTTOM LINE: Every public poll throughout the campaign (Liaison Strategies, Nanos, Canada Pulse Insights) has shown incumbent Olivia Chow leading challenger Brad Bradford by roughly 6–17 points, a gap that narrowed somewhat but persisted even after third-place Chris Alexander's withdrawal consolidated the "change" vote behind Bradford. Toronto's historical base rate strongly favors sitting mayors who seek re-election (Miller, Tory all won re-election when running again), and Bradford's own prior mayoral run ended in an eighth-place finish, making a Bradford win an uphill, below-base-rate outcome barring a late polling-era shift.
NOT FOUND: No fully independent third-party forecasting model (e.g., 338Canada-style) or betting-market consensus specifically for this race was located beyond the pollster figures cited; exact methodology/track-record comparison for Liaison Strategies vs. Nanos in past Toronto races was not found in the time available.
report: yes case
YES means: Brad Bradford is declared the winner of the October 26, 2026 Toronto mayoral election and is sworn in as mayor (not an interim/placeholder appointment).
- [2026-09-29] Rush frontman Geddy Lee made a rare political endorsement of Bradford, a high-profile cultural figure crossover that generated significant earned media for the challenger's campaign in the final month.
Geddy Lee has moved away from his usual public avoidance of political matters to make an endorsement in the upcoming Toronto mayoral election, coming out in favor of Toronto City Councillor Brad Bradford.
- [2026-10-06] Bradford's coalition-building extended into federal politics: three additional sitting Liberal MPs (Vince Gasparro, Leslie Church, Ali Ehsassi) publicly backed him, joining four other Liberal MPs already supporting his campaign, suggesting cross-partisan elite support beyond his Conservative base.
Candidate Brad Bradford has secured the endorsement of three more Liberal MPs: Vince Gasparro, Leslie Church and Ali Ehsassi joined four other Liberal MPs in supporting Bradford for mayor.
- [2026-07-13] Bradford's financial war chest is substantial and was framed by his team as momentum:
Brad Bradford says he's raised $1.8 million for his Toronto mayoral campaign, a display of financial firepower that would further solidify his evolution from an also-ran three years ago into a serious challenger
, with the campaign having
already taken in more than twice the $780,000 he raised for his run in the 2023 mayoral byelection
.
- [2025-06-~] Bradford's campaign was built early with elite backing: he
gathered 60 of the city's power brokers, organizers and fundraisers for a lunch at the Fairmont Royal York to sell the group—a mix of Liberals and Conservatives including Postmedia founder Paul Godfrey—on Bradford's ability to defeat Olivia Chow
, and an "Anybody But Chow" advocacy group (ABC Toronto) has been organizing to help defeat the incumbent.
- [2026-10-08] Bradford has secured endorsements from sitting city councillors and civic elders, including James Pasternak (Ward 6) who said
"I've served on City Council alongside Brad Bradford for the past eight years... Brad represents the change the city badly needs and deserves. On October 26th, I'm voting for Brad Bradford for mayor"
, and former Metro chair Paul Godfrey, who called Bradford
"the person to bring it back... a planner who understands how a city actually gets built, and he has the seriousness and the discipline the job demands."
- [2026-09-18] Polling trend shows real tightening at points in the campaign: a Mainstreet Research poll had
Chow leading Bradford 38.8 per cent to 31.4 per cent among all respondents
, with
nearly 17 per cent of respondents remain undecided, while 13.5 per cent say they could still change their minds
— a large volatile bloc Bradford needs to win disproportionately.
- [2026-09-23] A Liaison Strategies poll found Chow's lead had narrowed to single digits, down from double digits two weeks prior:
Olivia Chow leads Brad Bradford 47 per cent to 40 per cent among decided and leaning voters, down from an 11-point lead two weeks ago... Two weeks ago, Chow led Bradford 50 per cent to 39 per cent.
- [2026-09-~] Regional data show Bradford is competitive or leading in key growth suburbs:
Bradford led in Etobicoke with 50 per cent support, compared with Chow at 40 per cent
, and Scarborough and North York are described as closer battlegrounds than downtown, where
Liaison Strategies' latest poll has Chow leading Bradford 46 per cent to 41 per cent in North York and 46 per cent to 43 per cent in Scarborough
— margins within striking range if undecideds break his way.
- [2026-10-04] Nanos found Bradford running near-even with Chow among middle-aged voters, a demographic with higher turnout propensity:
Bradford... performed stronger among those 35 to 54 where he only trailed Chow by 2.8 per cent (46 per cent to 48.8 per cent), which is within the margin of error for the poll.
- [2026-10-06] Post-Alexander-withdrawal, Bradford gained ground in at least one debate-linked bounce, even if Chow retained her overall lead, per aggregator reporting already cited by colleagues (both candidates up two points, Chow's lead narrowing to seven).
- [2026-10-06] City Hall Watcher's own published forecast — built on 15 polls and 16,000 simulations through Oct. 6 — still gives Bradford a non-trivial path: the model shows
Chow finishes ahead of Bradford in 70% of simulated elections
, implying Bradford wins outright in roughly 26% of simulations (Bradford ahead by 2+ points), with a large "within 2 points" tail where turnout or late undecided breaks could flip the outcome.
- [2026-10-06] With Alexander out, commentary is split on effect: while Tumilty doubted a clean transfer to Bradford (per colleagues' report), the consolidation still mathematically simplifies the race to two names on a ballot where roughly a fifth of voters remained undecided as late as Sept./Oct. (20% undecided in the Canada Pulse Insights poll), giving Bradford a large pool to draw from if late "time for change" sentiment (55% in that poll) crystallizes behind him.
BOTTOM LINE: Bradford's path to YES runs through his demonstrated fundraising edge, broad elite/cross-partisan endorsements (Liberal MPs, Geddy Lee, veteran councillors, Paul Godfrey), his real regional strength in Etobicoke and competitiveness in Scarborough/North York, and a sizable (12–22%) undecided/persuadable bloc plus majority "time for a new mayor" sentiment in at least one poll — all of which the City Hall Watcher model itself still credits with roughly a one-in-four-to-three-in-ten chance of flipping the race by election day, October 26, 2026.
NOT FOUND: No poll has shown Bradford outright leading Chow at any point; no verified post-Oct-6 poll shows the Chow-Bradford gap closing below the ~4-point Forum Research margin; no data on advance-poll turnout patterns by borough that would confirm whether Etobicoke/Scarborough enthusiasm is translating into actual early votes for Bradford.
report: no case
YES means: Brad Bradford wins the October 26, 2026 Toronto mayoral election and is sworn in as the next mayor (not an interim/placeholder appointee). This dimension argues for NO — i.e., that Bradford does not win.
- [2026-10-06] City Hall Watcher's statistical model, fitted to the 15 published polls and seven past Toronto mayoral campaigns, states plainly:
"Olivia Chow is favoured to win," with Chow finishing ahead of Bradford in 70% of simulated elections.
The same model's own uncertainty decomposition shows that historical divergence between final polls and results is the dominant source of residual risk — results have "landed away from final polls" in 83% of the variance budget — yet even incorporating that large historical error term, Bradford is still projected ahead by 2+ points in only 26% of 16,000 simulations.
- [2026-09-18/19] Despite Bradford's team trying to frame Doug Ford's praise of Chow as proof she is "the easiest negotiation he has ever had," Ford's office explicitly walked back any endorsement, stating
his office explicitly stated the premier "did not endorse" Chow and "will not endorse any candidate" in the race
— denying Bradford a clean "Ford vs. Chow" wedge narrative that could have mobilized change voters.
- [2026-09-09 ongoing] The Toronto and York Region Labour Council's official endorsement record shows
Olivia Chow has served the people of Toronto for over three decades... As Mayor, she has stabilized Toronto's finances, got the city building again, and restored its public services, all while keeping taxes low
— institutional labour support is consolidated behind the incumbent, not Bradford.
- [2026-~] A dedicated opposition campaign, "Stop Brad" by Progress Toronto, cites a local petition in Bradford's own ward:
Over 640 (and counting) Beaches-East York constituents signed an open letter titled: "Brad Bradford failed as our councillor, he shouldn't be mayor"
— suggesting friction with his home base undercuts the "strong challenger" narrative.
- [2026-07-13] Bradford's campaign has leaned heavily on money rather than demonstrated voter conversion: reporting on his $1.8-million haul noted critics' rebuttal that
his political opponents argue that money doesn't translate into votes on election day, and that Mayor Olivia Chow can expect her own flood of donations as she ramps up her campaign
— i.e., no financial advantage has yet translated into a polling lead.
- [2026-10-04] Even with heavy advertising and a near-year-long campaign, independent analysis of endorsement effects found no clear mechanism for a late Bradford surge: pollster-analyst commentary noted it's "tough to say that one endorsement moves X amount of vote" and that measurable macro-level electoral impact remains unproven, undercutting any thesis that celebrity or political endorsements alone could flip the race for Bradford in the final weeks.
- [2026-10-06] Advance voting opened Oct. 6-11 with incumbent Chow and challenger Bradford both casting ballots early; no public data yet shows a turnout surge favoring Bradford specifically, and the city will not release advance turnout figures until Oct. 13, after Alexander's withdrawal already consolidated the race — meaning the single biggest recent shake-up (Alexander's exit) has not yet shown up in turnout data as benefiting Bradford.
- [2026-10-06] Bradford's own camp continues to attack Chow's record rather than show positive momentum of its own, with his team's statement that Chow "handed over on a silver platter" provincial leverage — a defensive, grievance-based message pattern consistent with trailing-candidate framing rather than a frontrunner's.
- [2023-06-26, reaffirmed 2026] Bradford's lone prior mayoral bid in the 2023 by-election remains the only directly comparable data point in his own electoral history, where he placed eighth, far behind Chow — he has never before led or won a citywide mayoral vote, a status-quo disadvantage that persists into 2026.
- [2026-10-07] Toronto's municipal election framework reinforces status-quo inertia: with 53 certified mayoral candidates and only Chow, Bradford, and (nominally) Alexander splitting meaningful support, Toronto's non-partisan FPTP system has not unseated a sitting mayor seeking re-election since amalgamation, and nothing in current turnout, endorsement, or fundraising data shows a structural break from that pattern by Oct. 26.
BOTTOM LINE: Every independent structural indicator available as of Oct. 8 — the aggregator model's win probability, institutional labour endorsements, the walked-back Ford signal, intra-ward opposition to Bradford, and the absence of any turnout or momentum data favoring him since Alexander's withdrawal — points to continuity (a Chow win) rather than change, reinforcing the case that Bradford fails to win and the market resolves NO.
NOT FOUND: No evidence of a Bradford campaign reboot, scandal involving Chow, or post-Oct.-6 poll showing Bradford ahead or within margin-of-error of Chow; official advance-voting turnout figures (due Oct. 13) were not yet available to assess base mobilization.

(0) Nothing is resolved yet. The City of Toronto elections page shows only logistics, and election day is October 26, 2026. Bradford would have to outpoll Olivia Chow on that day.
(a) That leaves about 18 days. Advance voting is already under way (Oct 6–11).
(b) If nothing changes, Chow wins. Every public poll has her ahead: Nanos about 52–43, Liaison 48–40, Canada Pulse 51–34, Forum 46–42. Toronto has not defeated a sitting mayor seeking re-election since amalgamation.
(c) NO scenario: Chow holds a 5–10 point lead, and Chris Alexander's roughly 4–9% splits or stays home, as Tumilty suggests. Chow's dominance in Toronto-East York and her lead in Scarborough carry her through.
(d) YES scenario: the 12–22% undecided bloc breaks toward 'time for change.' Bradford's money and endorsements (Liberal MPs, Geddy Lee, Godfrey) pull ahead in turnout in Etobicoke and North York. A typical municipal polling miss, which City Hall Watcher says dominates its error budget, closes the 4–9 point gap.
The market sits at 30%, up 18.5 points in a week, which looks like it is pricing Alexander's exit and the tighter Forum poll. The City Hall Watcher model, built on 15 polls, gives Chow about 70%, with Bradford ahead by 2+ points in only 26% of simulations. Adding the incumbency base rate and the absence of any poll showing Bradford leading, I shade slightly below the market to about 25%.

(0) Not resolved. The City of Toronto elections page shows only logistics and no results, and election day is October 26, 2026. (a) That leaves about 18 days, and advance voting is already underway. (b) Status quo is a Chow win. Every published poll from September through early October has incumbent Olivia Chow ahead of Bradford:
- Liaison: +8 to +9
- Nanos: about +10
- Canada Pulse: +17
- Forum: +4
City Hall Watcher's model, built on 15 polls and including historical poll error, gives Chow about 70%. Toronto has also not unseated an incumbent mayor seeking re-election since amalgamation. (c) NO: Chow holds a mid-to-high single-digit lead. Alexander's roughly 4–9% splits rather than moving to Bradford, as Tumilty suggests. Labour and downtown turnout carry her to victory. (d) YES: The race is now two-way after Alexander's October 6 exit. Undecided voters (12–22%) and a 'time for change' majority break late for Bradford. His fundraising, his endorsements (Liberal MPs, Geddy Lee, Godfrey) and his strength in Etobicoke, Scarborough and North York, plus a Forum-style polling miss, close the 4–9 point gap. The Polymarket anchor is 30%, up 18.5 points in seven days on the Alexander dropout and Forum poll. Chow's market sits at about 70.5%, which is consistent. The model's roughly 26–30% for Bradford and the base rate suggest the market is slightly rich after a momentum spike. With no poll showing Bradford ahead, I shade a little below the market to 26%.

The official Toronto elections page lists the upcoming vote but no result, so Bradford's victory is neither already established nor impossible. Election day is 18 days away on October 26; trading closes October 27 UTC, but the rules allow until June 30, 2027, at 11:59 PM ET for the result to become known. I retain Polymarket's 30% YES anchor (29% bid/31% ask): City Hall Watcher's October 6 model similarly has Chow ahead in 70% of simulations, and the research supplies no demonstrably unpriced development warranting a move. If current preferences persist, NO is the status-quo outcome: Nanos's September 30–October 4 survey puts Chow ahead 52.4–42.6 among decided voters, while October 6 Forum figures show a narrower 46–42 lead. A straightforward NO scenario is that Chow's incumbent and labour-backed coalition turns out reliably while Alexander's former supporters split or abstain rather than consolidate behind Bradford. YES remains plausible if Bradford's fundraising and cross-partisan endorsements help him capture a disproportionate share of the reported 12–22% undecided pool and generate stronger suburban turnout, although no supplied poll shows him leading. Toronto's undefeated post-amalgamation record for incumbents seeking reelection modestly favors NO, but the small historical sample deserves less weight than current polling, and missing post-withdrawal polling and turnout evidence limit confidence. Resolution requires credible-reporting consensus, with official Toronto information controlling ambiguity; routine reporting lag should not matter given the long fallback deadline, and only a negligible portion of my NO probability reflects the unresolved-result/Other contingency.

The condition is not already met or impossible: Toronto's official elections page provides voting logistics but no winner, and the supplied reporting describes an ongoing contest. There are 18 days until the October 26 election, trading closes October 27 UTC, and the rules allow the result to become known until June 30, 2027, at 11:59 PM ET. I retain Polymarket's 30% Yes anchor (29% bid/31% ask), because the research identifies no substantiated, unpriced development warranting a departure after its substantial recent rise. Nanos's September 30–October 4 survey put Chow ahead 52.4%–42.6%, Forum's October 6 poll showed a narrower 46%–42% margin, and City Hall Watcher's October 6 model gave Chow a 70% chance of finishing ahead. If current voting preferences persist, the status-quo outcome is a Chow victory and No. A concrete No scenario is that Chow's downtown strength and organized labour support sustain her lead while Alexander's former supporters split or abstain, with his name remaining on the ballot despite his withdrawal. A Yes scenario is that Bradford disproportionately captures the reported 12–22% undecided pool and Alexander supporters while stronger suburban turnout or correlated polling error closes the remaining gap; his fundraising and endorsements support that possibility but do not demonstrate a lead. Resolution requires credible reporting of the election winner, with official Toronto information controlling ambiguity rather than polling or projections; I include a very small allowance within No for a dispute or reporting delay lasting beyond the June 2027 cutoff and triggering the 'Other' fallback.

(0) The City of Toronto elections page shows only upcoming-election logistics and no winner, so the resolving condition has not been met; Bradford must win the October 26 election, with the result known by June 30, 2027. (a) There are 18 days until election day and roughly 19 days until the market closes. (b) If current conditions persist, Olivia Chow wins: every cited late-September or early-October poll has her ahead by 4–17 points, and the City Hall Watcher model gives her a 70% chance of finishing ahead. (c) NO results if Chow's polling advantage and incumbent strength hold, while Alexander's former supporters fail to transfer overwhelmingly to Bradford. (d) YES results if the effectively two-way race, Bradford's fundraising and cross-partisan endorsements, and the sizable undecided bloc produce a late change-voter break large enough to erase Chow's lead. I anchor near Polymarket's 30% YES price but move slightly lower to 28% because the poll aggregation assigns Bradford only about a 26–30% path, no poll has shown him leading, and Toronto has not defeated a reelection-seeking incumbent mayor since amalgamation.

(69% confidence)
Yes: 28%
No: 72%
Mean of 5 draws (0.25, 0.26, 0.30, 0.30, 0.28). (0) Nothing is resolved yet. The City of Toronto elections page shows only logistics, and election day is October 26, 2026. Bradford would have to outpoll Olivia Chow on that day.
(a) That leaves about 18 days. Advance voting is already under way (Oct 6–11).
(b) If nothing changes, Chow wins. Every public poll has her ahead: Nanos about 52–43, Liaison 48–40, Canada Pulse 51–34, Forum 46–42. Toronto has not defeated a sitting mayor seeking re-election since amalgamation.
(c) NO scenario: Chow holds a 5–10 point lead, and Chris Alexander's roughly 4–9% splits or stays home, as Tumilty suggests. Chow's dominance in Toronto-East York and her lead in Scarborough carry her through.
(d) YES scenario: the 12–22% undecided bloc breaks toward 'time for change.' Bradford's money and endorsements (Liberal MPs, Geddy Lee, Godfrey) pull ahead in turnout in Etobicoke and North York. A typical municipal polling miss, which City Hall Watcher says dominates its error budget, closes the 4–9 point gap.
The market sits at 30%, up 18.5 points in a week, which looks like it is pricing Alexander's exit and the tighter Forum poll. The City Hall Watcher model, built on 15 polls, gives Chow about 70%, with Bradford ahead by 2+ points in only 26% of simulations. Adding the incumbency base rate and the absence of any poll showing Bradford leading, I shade slightly below the market to about 25%.
