Prime Minister Mark Carney and Ontario Premier Doug Ford made a very significant announcement that will have a decided effect on real estate in the Province of Ontario.   The federal and provincial governments committed to a combined $8.8 billion over the next decade in part designed to cut municipal development charges in half for the next three years.  If you're a buyer, seller, developer, or anyone who cares about housing affordability in Ontario, this is a significant development.   

What Are Development Charges — and Why Do They Matter?

Before we dive in, for those who do not know what development charges are.  Development charges, of DCs as they are often called, are fees collected from developers and builders to help pay for the cost of all the infrastructure required to provide municipal services to a new development.  Think things like roads, transit, water and sewer infrastructure, community centres and the like.   

The idea is that if you want to build then you pay -  not the existing tax payers.  In practice, DCs in Ontario have become one of the most significant drivers of new home costs — and they have grown at a pace that it is creating a serious challenge for those who see housing affordability as a crisis.

Let's take Toronto as an example.  According to ConstructConnect, in Toronto, DCs for single-detached homes increased from $12,910 in 2010 to $141,139 in 2024 — a 993 per cent hike.  Ontario municipalities collected over $4 billion in annual DCs by 2022, a fourfold increase over 2010. Development charges have increased by as much as 1,000 per cent in the last decade and a half, and range from tens of thousands of dollars in smaller municipalities to as much as $130,000 per single-family home in the GTA.

The burden on homebuyers is real and direct. Depending on the source, and of course the municipality, DCs can add up to 25 to 30 per cent to the cost of a new home.  And those costs don't disappear — they are passed to buyers in the form of higher purchase prices, or to tenants in the form of higher rents.

The funding flow diagram above illustrates how the money moves between the three levels of government and ultimately reaches builders and buyers.

The Announcement: What Was Actually Promised

What the Prime Minister has announced specifically (you can read the full release here) is that: 

"The federal government and Ontario will cost-match a total of $8.8 billion over 10 years, focused on housing-enabling infrastructure projects. This funding will support the reduction of municipal development charges by up to 50%, with reductions in place for three years, targeting municipalities covering 80% of the province's population".   

So we are clear, this isn't a blank cheque to municipalities. As Premier Ford said:  "If you don't cut DCs, you aren't getting any money."

The agreement offers very significant incentives to municipalities to give them funding to help pay for infrastructure, so they can reduce development charges by 50 per cent over the next three years.  But again, the municipalities will also be expected to actually reduce the DCs.   

it should be noted that this announcement also builds on the deal struck just days earlier: the full 13% of the HST will be removed for new homes in Ontario valued up to $1 million, saving buyers up to $130,000. That announcement goes on to say: "This maximum rebate would be maintained for new homes valued up to $1.5 million, and would decrease proportionally from $130,000 at $1.5 million to a maximum of $24,000 for homes valued at $1.85 million and above applying to eligible agreements signed between April 1, 2026, and March 31, 2027.

So the take home here is that when combined, this partnership is expected to reduce taxes and fees for a home in Ontario by up to $200,000.

What It Means in Dollars: A Buyer's Breakdown

The savings chart above shows estimated combined savings at different price points for a new home in the GTA. The stacked bars represent the DC reduction (blue) and HST removal (green) components side by side.

For a buyer purchasing a new $1 million home in Toronto, for instance, the potential savings are substantial: roughly $65,000 from the DC reduction, and up to $130,000 from the HST exemption — a combined benefit approaching $195,000 on the total cost of acquisition.

The economic ripple effects are expected to be significant as well. The province estimated the combined measures would deliver nearly $2.2 billion in tax relief, support an additional 8,000 housing starts next year, create up to 21,000 jobs, and add $2.7 billion to Ontario GDP.

Transit Infrastructure: The Broader Vision

The announcement went beyond development charges and taxes. Canada and Ontario are also collaborating on several major transit infrastructure projects, including the Waterfront East transit line — a three-way partnership between the federal government, the Province, and the City of Toronto to build the transit line serving Toronto's eastern waterfront, including the East Bayfront and Port Lands. The line will serve more than 150,000 people, support over 50,000 daily trips, and is expected to enable 75,000 housing units. Prime Minister of Canada The announcement also included commitments around GO Transit expansion and the Alto High-Speed Rail initiative.

Industry Reaction

The response from the building industry was unequivocal. The Building Industry and Land Development Association (BILD) and the Ontario Home Builders' Association (OHBA) applauded the announcement, with OHBA CEO Scott Andison calling it historic, noting that "in an environment where government fees, charges, and taxes have historically added 25 to 30 per cent to the cost of a new home, lowering development charges" at this scale could be transformational for housing project viability and affordability. The Manila Times

Toronto Mayor Olivia Chow signalled her city's readiness: "The city is ready, homeowners are ready, a program is in place, and there's absolutely no time to waste."

What to Watch For

A few important nuances to keep in mind as this policy rolls out:

• Municipal participation isn't automatic. Municipalities must apply to the program and formally commit to reducing DCs. Not every municipality will move at the same pace, and the size of the reduction will vary by community.
• The DC reduction has a three-year window. This is not a permanent restructuring of how development charges are calculated; it is a time-limited subsidy designed to jumpstart supply. The long-term framework for DC funding in Ontario remains an open question.
• The HST exemption runs for one year. Eligible agreements must be signed between April 1, 2026 and March 31, 2027, making timing a factor for buyers and builders alike.
• Property tax implications. Some analysts have noted that if municipalities forgo DC revenue without a full offset from provincial and federal funding, there could be downstream pressure on property taxes for existing homeowners. The program is designed to compensate municipalities for the revenue gap, but the details of that compensation will be worked out municipality by municipality.

The Bottom Line

This is the most significant housing affordability intervention Ontario has seen in a generation. For buyers who have been sitting on the sidelines waiting for conditions to improve, the combination of dramatically lower development charges on new builds and a one-year HST holiday creates a window that is genuinely unprecedented. For builders, lower upfront costs may be the difference between viable and unviable projects — particularly in the condo and purpose-built rental segments where margins have been razor-thin.

The hard work of implementation  i.e. getting 80% of Ontario's municipalities to formally commit, processing infrastructure applications, and ensuring the money flows quickly, is going to determine whether the ambitious targets translate into cranes in the sky. But as an opening move, this announcement is as consequential as it gets.
