What's Changing for GTA Homeowners in 2026: Permits, Rebates and Taxes

Eight months into 2026, the changes that reach a GTA homeowner's chequebook are narrower than the headlines suggest. Property taxes rose by three different amounts across Toronto, Mississauga and Brampton. Permit fees reset on January 1, as the by-law makes them do every year. Development charges came down, conditionally, and the condition has not been met. Federal retrofit grants closed while two Ontario programmes stayed open. Each item below carries its governing decision, its effective date and its condition.

Property tax: three cities, three numbers

Toronto City Council adopted the 2026 Budget on February 10, 2026. The residential increase is a 0.7 per cent operating levy (multi-residential and commercial got 0.35) plus a dedicated 1.5 per cent City Building Fund levy: a combined 2.2 per cent, or $91.53 per year ($7.63 per month) on a home at the Municipal Property Assessment Corporation's average current value assessment of $692,140.

Read that 2.2 per cent carefully: it is the increase on the City's share of your bill, not on the bill. The 2026 rate table splits the residential rate into a City rate of 0.605295 per cent, an education rate of 0.153000 per cent and a City Building Fund rate of 0.009016 per cent, totalling 0.767311 per cent; the City's own worked example is 692,140 × 0.767311 per cent = $5,311. The education slice is set by the Province, not Council, so Council's increase does not touch it: $91.53 against a $5,311 bill is about 1.7 per cent of the whole.

Mississauga's figures come from the March 10, 2026 report that set the rates. A 4.39 per cent City budget increase works out to 1.61 per cent of the total residential bill and Peel's 7.4 per cent to 3.60 per cent, taking taxes per $100,000 of assessment from $1,034.22 to $1,087.90. Of that, $16.46 is City and $37.22 Region, so seven of every ten dollars is regional. The City's budget FAQ says "about $16.66"; the March report is the rate-setting document and states $16.46. It also confirms the Province has billed residential education taxes at the same 0.153 per cent since 2020.

Brampton's February 6, 2026 budget held the City portion at zero and continued a 1 per cent levy for the second hospital reserve, part of a provincially required $125 million municipal commitment. The $73 is the City share with that levy included; the Region of Peel increase lands on a Brampton bill separately.

The City Building Fund schedule ends with this year

Toronto's rate page records the decision: on December 17, 2019 Council added one per cent in 2020 and 2021 to the existing 0.5 per cent increment, plus an additional 1.5 per cent annually from 2022 to 2026, inclusive. 2026 is the last year of that schedule. Anything after it is a fresh Council decision, not an automatic continuation.

Vacant Home Tax: the rate held, the calendar moved

The rate did not change: 3 per cent of Current Value Assessment beginning with the 2024 taxation year.

The 2025 declaration window opened November 3, 2025 and closed April 30, 2026, covering occupancy from January 1 to December 31, 2025. Every residential owner must declare annually, even for a principal residence, and a property counts as vacant if it was empty for six months or more in the taxation year. Miss the deadline and the City assumes it was vacant and bills it. Notices go out in June, and the 2025 tax is payable in three equal instalments on September 15, October 15 and November 16, 2026. Overdue amounts attract interest at 1.25 per cent on the first day of default and on the first of each month after. The deadline to dispute a 2025 bill is December 31, 2026, and a false declaration, or failing to provide information when asked, can draw a fine of up to $10,000 on top of the tax.

Permit fees: January 1 is not a coincidence

Toronto's permit schedule is dated "effective January 1, 2026" line by line, which is the by-law working as designed rather than a one-off increase. Municipal Code § 441-4A says all fees flagged for annual adjustment in Column VI of the appendices "shall be adjusted annually, effective January 1", by an amount the Chief Financial Officer and Treasurer sets under the User Fee Policy; § 441-4C makes that section prevail over any conflicting chapter. Building permit fees sit there, in Schedule 8, Toronto Building, because § 363-4.1A sends every fee the building chapter requires to Chapter 441.

For 2026 that puts the minimum permit fee at $214.79 for all work and the examination and inspection hourly fee at $92.79. Treat the minimum as a floor, not an add-on: § 363-4.3C says total permit fees "shall not be less than the minimum fee set out in Chapter 441". That floor swallows small jobs: interior alterations run $11.53 per square metre of work involved for Groups C, E and F, which covers houses, so anything under 214.79 ÷ 11.53 = about 18.6 square metres costs the $214.79 minimum rather than the per-metre rate.

Mississauga runs the same cycle. Its 2026 Fees and Charges schedule was set to be implemented as of January 1, 2026, "with some exceptions to align with business areas", most fees updated for inflation estimated at three per cent. Building permits are among the user charges it covers.

Toronto's development charges are set to come down, conditionally

The largest single change of the year for anyone building. After a March 30, 2026 Canada–Ontario announcement and a June 23, 2026 award of $1.5 billion to Toronto, the City's July 28, 2026 presentation sets out development charge reductions of 40 to 60 per cent for all residential development, plus removal of the annual indexing that would otherwise raise rates from 2027 to 2029. The discount is not uniform: studio and one-bedroom units get 40 per cent, everything else 60. For a non-rental single or semi-detached house the current rate of $137,846 would fall to $55,138 under the proposed schedule.

Three conditions travel with it. Eligibility runs on the first building permit, defined as any permit to construct under section 8 of the Building Code Act, 1992 and expressly excluding site servicing, demolition, drain, plumbing, HVAC and temporary sales office permits, so pulling a mechanical permit does not start your clock. The above-grade permit must follow by the end date or within 24 months of the first building permit, whichever is later, and cannot be revoked before occupancy. There is no application process and no programme cap; eligibility is automatic.

Now the asterisk. The eligibility window reads "March 30, 2026, and August 2029" with a star beside it, and the footnote says the exact date will be three years after the execution of the Transfer Payment Agreement with the Province, expected in mid-August 2026. The end date is not fixed at all: it moves with the signing, and so does the programme, because the amended by-law "will come into effect upon execution of the TPA", which the City expected by August 15. As of August 26, 2026 its development charges page still says Council adopted the by-law "subject to a Transfer Payment Agreement with the Province of Ontario" and that "additional information will be available once the Agreement is received". Confirm the rate with Toronto Building on the day you apply.

Adding a unit is governed by an older, unchanged rule: section 2(3.2) of the Development Charges Act, 1997 exempts a second residential unit in an existing detached house, semi-detached house or rowhouse from development charges, subject to the conditions that section sets out, and section 2(3.3) does the same for new houses. The exemption is from development charges only. The building permit fee is separate, and it is re-set every January 1.

Rebates: the federal grants closed, Ontario's programmes did not

Per Natural Resources Canada's pages dated August 4, 2026, the Canada Greener Homes Grant is closed (December 31, 2025 was the last day to submit documents) and the Canada Greener Homes Loan is closed to new applications, approved ones unaffected. The Canada Greener Homes Affordability Program runs through provincial partners and Ontario is not among them.

The Oil to Heat Pump Affordability program is where coverage goes wrong. It stopped taking applications on July 31, 2026. But that page is explicitly for applicants in Alberta, Manitoba, the Northwest Territories, Quebec and Saskatchewan, the jurisdictions Ottawa delivers itself. Ontario is a co-delivered province, and NRCan's participating provinces page says eligible Ontario homeowners can apply for free direct installation of a heat pump system valued at up to $25,000 (up to $15,000 federal and up to $10,000 provincial), with no money paid to the applicant except a $250 bonus cheque.

It runs through Save on Energy's Energy Affordability Program, which is income-qualified and open, and under which a cold climate air source heat pump is available to homes heated by electricity or oil. You qualify as the primary or secondary utility account holder if your before-tax household income last year was at or below the limit ($48,220 for one person, $96,439 for four), or if you received a listed support such as ODSP or the Guaranteed Income Supplement in the past 12 months. Everything installed is free of charge.

Everyone else buys through Ontario's Home Renovation Savings Program, whose amounts turn on how your home is heated today. The same cold climate air source heat pump carries a per-ton rate two and a half times higher, and a cap nearly four times higher, in a home heated with electricity, oil, propane or wood than in one on natural gas. Renting rather than buying drops you to the natural gas amounts whatever you heat with. Air source amounts are calculated on minimum rated heating capacity at 8.3C, the non-gas ground source rate on closed loop capacity, so a smaller unit means a smaller cheque whatever the invoice says. And pre-approval is mandatory: installations done before approval are not eligible.

Two Toronto notes. Toronto Hydro's Heat Pump Assistance Program is closed to applications: its 200 households are recruited and installations continue through 2026. And the City said in September 2025 that its BetterHomesTO Furnace Upgrade Program would expand in 2026 to add installation services and "targeted incentives for low-to-moderate-income households", alongside a Home Energy Loan Program the 2025 Budget topped up by $20 million for low-interest heat pump loans. As of that page's August 20, 2026 update no incentive amounts are published and only the free energy coaching is live. Treat the incentives as announced, not available.

The Building Code changed again in July

Ontario's Building Code, O. Reg. 163/24, now carries a consolidation period beginning July 22, 2026, its last amendment O. Reg. 242/26, and it adopts the National Building Code of Canada 2020 as amended by the Ontario amendment document dated July 17, 2026. Three amending regulations landed in 2026 alone. What they changed we cannot tell you from the Ministry's own Building Code updates page, which listed amendments only as far as O. Reg. 5/25 when we read it on August 26, 2026. The consolidated regulation on the King's Printer site is authoritative and well ahead of that summary.

Dates still left on the 2026 calendar

The relief deadline needs a look: the City's pages disagree. The February 3, 2026 interim tax bill release says "Friday, October 31". But October 31, 2026 is a Saturday. The relief program page and an August 4, 2026 news release both give Monday, November 2, 2026, and October 31 does a different job on that page: it is the date by which you must have owned and occupied the home as your principal residence for a year or more. Take the later date. Behind it sit the Property Tax Increase Cancellation Program (combined household income not over $62,000, assessment below $975,000, plus an age or disability test), the Increase Deferral Program and the water and solid waste rebates. Reapply every year.
