Guelph's Next Mayor and Your Property Tax Bill

How much control does Guelph’s mayor have over property taxes?

Guelph’s mayor has Ontario’s strong mayor powers, so the mayor, not council, proposes the City budget. Council can amend it, the mayor can veto those amendments, and overriding a veto takes two-thirds of all council members. The mayor doesn’t control your whole tax bill, though. Local boards like police and the library run their own budget processes, and those made up more than half of Guelph’s 7.87% levy increase in 2026. For 2027, the City forecasts a 7.48% increase, and 4.72 percentage points of it comes from City services, which is the part the mayor’s budget covers.

Guelph votes for mayor on Monday, October 26. Cam Guthrie isn’t seeking re-election, so this is the city’s first change of mayor since 2014. It’s also the first time a new Guelph mayor starts the job with strong mayor powers already in place. Voting locations and options are on the City of Guelph’s election page.

If you own a home here, or you’re planning to buy one, the budget process deserves a few minutes of your attention. I’m not endorsing anyone. This is how the system works, so you can ask better questions before you vote.

How the strong mayor budget works

Guelph is one of the Ontario municipalities designated under the province’s strong mayor rules (Part VI.1 of the Municipal Act and O. Reg. 530/22). The province’s guide to strong mayor powers and duties lays out the full process. Under those rules, the mayor proposes the municipal budget, and the usual deadline is February 1. There are special timing rules for the year after an election, so the next mayor’s first budget may not follow the usual calendar. This is the process that decides the City services share of your property tax bill.

Once the mayor tables a budget:

Council has up to 30 days to amend it.
The mayor has up to 10 days to veto those amendments, with written reasons.
Council has up to 15 days to override a veto. An override takes two-thirds of all council members, not just two-thirds of the people at the meeting.
If council doesn’t override it, the budget stands as adopted.

Council still debates and votes on amendments. The big shift is that the mayor writes the starting draft and can veto changes to it.

There’s a second power. For bylaws the mayor believes would advance a provincial priority, including housing, a mayor-proposed bylaw can pass with more than one-third of all council members. It covers specific kinds of bylaws only. It isn’t a way around planning rules or a blanket power to approve development.

What Guelph’s property tax numbers say

The City’s confirmed 2026 budget shows a 7.87% total property tax levy impact, made up of:

3.36 percentage points for City services
4.40 percentage points for local boards and shared services (police, library, public health and similar)
0.11 percentage points for the Guelph General Hospital levy

The City’s illustration is $401.62 more per year for a median single-family detached home with a 2025 assessed value of $410,000, using 2025 tax policy. That breaks down as $171.47 for City services, $224.54 for local boards and shared services, and $5.61 for the hospital levy.

Two points of context. That $410,000 is an MPAC assessed value, not what detached homes sell for in Guelph today. And the City notes that local boards and shared services follow their own legislation and budget timelines, separate from the strong mayor process. The mayor has real influence over the overall picture but doesn’t write every line of it.

The 2027 property tax forecast

The City’s 2026 budget table includes a forecast for 2027: a 7.48% total property tax levy increase, with 4.72 percentage points of that from City services.

That’s a shift from 2026. Last year, local boards and shared services drove more than half of the increase. In the 2027 forecast, the larger share comes from City services, the portion the mayor’s budget directly covers. The board portion still needs its own scrutiny, but more of next year’s forecast increase falls on the budget the new mayor will table.

Keep in mind it’s a forecast, not a decision. The new mayor and council will set the real number, and 2027 is the last year of the current 2024–2027 multi-year budget. Council will build the next one, covering 2028 to 2031, during this term.

If you want to see how growth costs fit alongside the tax levy, I broke down Guelph’s development charges and what they fund. Both pay for the same roads, pipes, and facilities.

Why property tax matters if you’re buying or selling

Property tax is part of the monthly cost of owning a home, and your lender includes it when they qualify you.

When I help buyers compare homes, we look at the taxes on each specific property, not a citywide percentage. Future bills can change, so I’ll point to the City’s published forecast as a guide, but I won’t treat it as a quote for one house.

For sellers, taxes rarely decide a sale. Buyers do compare the full monthly cost of every home on their shortlist, though, and an accurate number beats a guess either way. For where prices and sales sit right now, my September 2026 Guelph market update has the latest local numbers.

A note for Centre Wellington

Centre Wellington also has strong mayor powers, which it received in 2025, and the township lists its mayoral decisions on its Strong Mayor Powers page. Mayor Shawn Watters delegated the administrative powers the law allows him to hand off, like those related to the CAO and the township’s organizational structure. The budget duty isn’t one of the powers that can be delegated. If a mayor doesn’t propose a budget by the deadline, council prepares and adopts it instead. That’s a fair question to put to candidates there, too.

If you’re buying new construction in Fergus or Elora, I covered how much Centre Wellington’s development charges increased this year, which is separate from the township’s property tax rate.

Questions worth asking before you vote

The City forecasts 4.72 percentage points from City services in 2027. Is that your target, and if not, what changes?
How would you build the City services budget with council and the public?
If council amended your budget, when would you use a veto?
How would you talk with residents about the cost pressures from local boards and shared services?
Would you ever use the provincial-priority bylaw power for housing, and how?

The answers will tell you more than any promise about what your property tax bill will be in four years.

Frequently Asked Questions

Does Guelph’s mayor set my property tax bill?

Not alone. The mayor proposes the City budget under Ontario’s strong mayor rules, and council can amend it and override a veto with two-thirds of all members. Local boards and shared services have their own budget processes, and your bill also depends on your property’s assessment and the City’s tax policy.

When is Guelph’s 2026 municipal election?

Monday, October 26, 2026. Check the City of Guelph’s election page for voting locations and options.

How much did Guelph property taxes go up in 2026?

The City reported a 7.87% total tax levy impact for 2026. Its example is $401.62 more per year for a median detached home assessed at $410,000 in 2025. Your own increase depends on your property. The City’s forecast for 2027 is 7.48%, with 4.72 percentage points of that from City services.

Did Centre Wellington’s mayor give up his strong mayor powers?

No. Mayor Shawn Watters delegated certain administrative powers, such as those related to the CAO and the township’s structure. The mayor can’t delegate the duty to propose the budget.

The bottom line

Whoever wins on October 26 will have a strong voice in Guelph’s City budget for the next four years, including the 2028–2031 plan. Council still has a real role, and part of your property tax bill comes from boards with their own processes. The best candidates will be able to explain that clearly.
