The problem

What is happening?
Three issues dominate Mississauga's 2026 mayoral race: housing affordability and intensification, a cluster of AI data centre proposals, and transportation and congestion.

On housing, the city has spent three years arguing about how much density to allow and how much to charge for it. In Oct. 2023 Council voted on allowing four homes on qualifying low-rise lots; the decision mattered to Mississauga's federal Housing Accelerator Fund application, with roughly $113M at stake. Council rejected fourplexes and then-mayor Bonnie Crombie used strong-mayor powers to implement them anyway. In Jan. 2025 the Housing Task Force brought a 50% residential development-charge reduction, and 100% for qualifying 3-bedroom purpose-built rentals. In Mar. 2026 the Affordable Rental Housing CIP envelope grew from $44M to $70M, with $26M from federal Housing Accelerator Fund reserves.

On data centres, a proposed hyperscale facility triggered organised resident opposition. In July 2026 Council proposed a pause of up to one year on large-scale data centres while the City studies infrastructure, water, electricity, environmental and land-use impacts. Alvin Tedjo argues a proposed 200,000+ sq.-ft. facility could consume roughly 100 MW. Dipika Damerla has argued residential utility customers should not subsidise data centres.

On transportation, the 2024 budget put $87.9M into hybrid-bus acquisitions and nearly $4M into MiWay service improvements, with nearly $2B planned over 10 years for transit capital.

Who is affected?
Renters, first-time buyers and families priced out of ownership; residents near proposed data centre sites who face infrastructure, water and electricity pressure; and MiWay riders and drivers dealing with congestion. Ratepayers are affected on all three, through development charges, utility costs and the transit capital plan.

When did it become an issue?
Housing intensification became a live council fight in Oct. 2023. The data centre issue emerged in 2026, with resident organising reported in July 2026 and the Council pause proposed the same month. Transportation and congestion are long-running.

Inherited or self-inflicted

Partially.
Carolyn Parrish became mayor in the 2024 by-election, so she has been mayor for less than two years. The housing intensification fight predates her: the Oct. 2023 fourplex vote and the strong-mayor override happened under Bonnie Crombie, who was mayor from 2014 to 2024 and resigned to lead the Ontario Liberal Party. The Housing Accelerator Fund application and the $113M attached to it also predate Parrish's term. Congestion and transit capacity are long-running suburban problems no single mayor created.

The data centre proposals are newer and arrived on her watch.

Did they create any part of the problem?
There is no evidence Parrish created the underlying problems. She has shaped their direction: she created the Mayor's Housing Task Force, sponsored the Jan. 2025 development-charge reductions, and did not vote on the July 2026 data centre pause, saying the chair of Council remains neutral — a choice Bonnie Crombie criticised.

What they did

Housing
Oct. 2023 — fourplexes as-of-right: Council rejected allowing four homes on qualifying low-rise lots; Mayor Bonnie Crombie used strong-mayor powers to implement them. Roughly $113M in federal Housing Accelerator Fund money was at stake. Parrish voted YES. Damerla voted NO. Tedjo voted YES.
Jan. 2025 — Housing Task Force incentives: a 50% residential development-charge reduction, and 100% for qualifying 3-bedroom purpose-built rentals. Parrish was the mayor and motion sponsor. Damerla and Tedjo voted YES. Foregone revenue varies by project.
Mar. 2026 — Affordable Rental Housing CIP expansion: the program envelope grew from $44M to $70M, with $26M from federal Housing Accelerator Fund reserves. Parrish's vote is not recorded. Damerla abstained. Tedjo voted YES.

Data centres
July 2026 — pause/review of large-scale data centres: a proposed pause of up to one year while the City studies infrastructure, water, electricity, environmental and land-use impacts. Parrish did not vote. Crombie criticised that non-vote. Damerla's vote needs to be treated separately from the mayor's non-vote. Tedjo's vote record needs to be verified before assigning a position.

Transportation
2024 budget — transit investment: $87.9M for hybrid-bus acquisitions, nearly $4M in 2024 MiWay service improvements, and nearly $2B planned over 10 years for transit capital. Parrish and Crombie supported the budget as mayors; Damerla and Tedjo voted with Council on budget-related measures as councillors.

Better or worse

Same

Mixed.
Housing: more is being approved. Parrish says nearly 18,000 units are now in process or under construction, and the City has layered development-charge reductions and an expanded Affordable Rental Housing CIP on top of as-of-right fourplexes. Whether that produces affordable homes is unresolved. Critics argue supply-only approaches benefit developers without guaranteeing affordability, tend to produce luxury units, ignore tenant protections and rent pressures, and prioritise growth over community and environmental concerns.

Data centres: the City has moved from no policy to a proposed one-year pause and study, which is progress on process. No outcome yet.

Transportation: significant capital is committed, but no outcome data showing congestion has improved was found in the source research.

Verdict: Mixed. Action on all three, outcomes proven on none.

Leadership

Proactive on housing, notably passive on data centres.
Housing: Proactive. Parrish created the Mayor's Housing Task Force early in her term and sponsored the Jan. 2025 development-charge reductions, making housing supply a defining priority.

Data centres: Passive at the decisive moment. Council moved toward a pause, but Parrish did not vote on the July 2026 motion, saying the chair of Council remains neutral. Bonnie Crombie criticised the decision not to vote, and the mayor's own position on the city's newest large land-use question is therefore not on the record.

Transportation: Proactive in funding, with the Hazel McCallion LRT, all-day two-way GO on the Milton corridor and future MiWay infrastructure among her stated priorities, alongside housing-enabling roads.

Other: Parrish said during the campaign she would try not to rely on Ontario's strong-mayor powers and preferred building consensus, then used them within days of taking office to remove Mississauga's top bureaucrat and reorganise senior city leadership. She resigned from the Peel Police Services Board during the 2025 budget fight over a 23.3% policing increase, and Council ended the raising of foreign national flags at City Hall in April 2026.

Were there warnings

Residents: The Pointer reported in July 2026 that Mississauga residents were organising against the city's first hyperscale data centre proposal, under the banner "Shut it down".

Candidates: Alvin Tedjo warned that a proposed 200,000+ sq.-ft. facility could consume roughly 100 MW, putting pressure on local infrastructure and residents. Dipika Damerla warned that residential utility customers should not subsidise data centres and raised concerns about their electricity and water consumption.

Housing critics: Critics of the Housing Task Force approach warned that supply-only strategies can benefit developers without guaranteeing affordability, produce luxury units more than affordable homes, ignore tenant protections and rent pressures, and prioritise growth over community and environmental concerns.

How did the municipality respond?
On data centres, Council responded within the same month, proposing a pause of up to one year and a study of infrastructure, water, electricity, environmental and land-use impacts. Parrish did not vote. On housing, the City responded by expanding incentives rather than by adding affordability or tenant-protection conditions.

Verdict: Warnings were recent and the response on data centres was fast. The housing warnings have not been directly answered.

The alternatives

Fourteen candidates were certified for mayor. The substantive alternatives with published platforms are:

Bonnie Crombie — the former mayor (2014–2024) and former Ontario Liberal leader, running on experience, affordability, safety and getting City Hall moving again. Pro-housing supply; she used strong-mayor powers to implement fourplexes after Council rejected them. Supports greater data-centre scrutiny and criticised Parrish for not voting. Cites her record on the Hurontario LRT, Dundas/Lakeshore BRT and all-day GO.

Alvin Tedjo — Ward 2 councillor, second in the 2024 by-election. The clearest pro-intensification housing platform: missing middle, density on major streets and transit corridors, faster approvals. The clearest data-centre opposition: "NO. NEW. DATA CENTRES." Wants a rapid-transit grid and a Dundas East LRT to Toronto.

Dipika Damerla — Ward 7 councillor, former MPP and cabinet minister, third in 2024. More cautious on intensification (voted NO on fourplexes, abstained on the Mar. 2026 CIP expansion). Argues residential utility customers should not subsidise data centres. Focused on transit reliability, tax restraint and an independent Auditor General.

Mike Matulewicz — retired Toronto Police officer. Affordable housing and community land, environmental monitoring, and major transit investment funded partly through a proposed fuel levy.

Among the lower-profile candidates, only Ana Luisa Vasquez De Espinal has documented positions on the core issues: she backs the moratorium on unreviewed hyperscale data-centre approvals pending grid-capacity and air-quality studies, and would inspect the city's water, sewer, road and transit systems in Year 1 before committing to major spending. Gord Elliott, a self-employed printer who ran federally as an independent in 2021, campaigns on tenant protections, housing affordability and making developer-council meetings public. Karam Ahmed, from the automotive and towing industry, runs on lower property taxes and more police support against auto theft. Amjad Jilani, Frank Fang and David Shaw have platforms but none addressing the data centre question. No public record beyond a name and a filing date was found for Aamir Bhatti or Mohsin Khan.

How are they different from Parrish?
Parrish: build fast, cut development charges, review data centres without stating a position, fund transit capital.
Crombie: same pro-growth direction with a longer record and an explicit data-centre position.
Tedjo: further on density, explicitly against new data centres, more ambitious transit.
Damerla: slower on intensification, harder on who pays for data centres, focused on making existing services work.

Best placed to fix it

Unclear

On the three main priorities, Alvin Tedjo has the clearest pro-intensification approach to housing, while Carolyn Parrish and Bonnie Crombie also strongly support housing growth. Mike Matulewicz emphasises affordable housing and community land, while Dipika Damerla takes a more cautious approach to intensification. On AI data centres, Tedjo and Damerla have taken the clearest positions, while Parrish did not vote on the pause and most other candidates have not clearly stated their views. For transportation and congestion, Crombie and Tedjo have the strongest transit-expansion platforms, with Parrish also supporting major infrastructure investment; Matulewicz proposes dedicated transit funding, while Damerla focuses more on transit reliability and improving existing services.
