Evan Siddall Returns to Federal Housing Policy as Build Canada Homes Chair
The man who warned that Canadian housing had become a "financial accident waiting to happen" is now tasked with building his way out of it. Evan Siddall's appointment as inaugural Chair of Build Canada Homes marks the most aggressive federal pivot toward direct construction since the post-war Wartime Housing program, and the most pointed acknowledgment that the government can no longer afford to finance its way past a supply crisis.
Siddall ran the Canada Mortgage and Housing Corporation from 2014 to 2021, where he earned a reputation as the bureaucrat willing to say the uncomfortable part out loud. He pushed stress testing when the industry howled. He called household debt levels "dangerous" when the prevailing view was that Canadians could manage. His departure to AIMCo in 2021 was read by many as a mutual parting: the feds wanted someone less alarmist, and Siddall wanted to stop being the guy writing reports nobody acted on.
His return signals something different. Build Canada Homes isn't a risk-mitigation shop. It's a Crown corporation built to take on projects private developers won't touch, high-density builds on underutilized federal land, mixed-income developments with thin margins, transit-oriented housing in cities where zoning has been a bloodsport for decades. The mandate is not to insure mortgages or issue reports. It's to pour concrete.
The structural problem Siddall inherits
The federal government has spent the last decade financing housing. CMHC backstops mortgages. The Canada Infrastructure Bank funds rental projects. Billions have flowed through the National Housing Strategy. But financing only works if someone is willing to build, and the last two years have shown what happens when interest rates spike and construction economics collapse. Starts fell. Private capital retreated. The 3.5 million units CMHC says Canada needs by 2030 became a gap nobody could close with loans alone.
Build Canada Homes was created to fill that gap. It has a $15 billion revolving fund and the legal authority to acquire land, issue tenders, and act as developer of record. The model is less "partner with the private sector" and more "do it ourselves when the private sector won't." That's a return to direct federal delivery not seen since the 1940s, when Wartime Housing Limited built 46,000 homes in six years by treating shelter as infrastructure instead of product.
Siddall has referenced that program before, usually to make the point that speed and scale require stripping out the consultation layers that make housing approvals feel like trench warfare. Whether he can actually do that as chair of a Crown corporation subject to federal procurement rules and local zoning constraints is the open question.
What changes under Siddall's chairship
The immediate work is operational. Build Canada Homes is slated to reach full capacity in late 2026, which means Siddall's first year will be about assembling the technical capacity to evaluate sites, price bids, and move dirt. The corporation will coordinate with CMHC on financing and with the Infrastructure Bank on project bundling, but the decision on what gets built and where sits with Siddall's board.
The longer play is political. A Crown corporation building social housing in Toronto and Vancouver will compete for the same skilled trades, the same concrete suppliers, and the same permitting bandwidth as private developers already starved for all three. The construction industry has made it clear they see Build Canada Homes as a potential bottleneck, not a solution. Siddall's job will be to prove the model can scale without breaking the market further.
He spent seven years at CMHC warning that the system was fragile. Now he's running the program designed to rebuild it from the ground up. If it works, the feds get a functioning developer that can deliver units at scale without waiting for market conditions to improve. If it doesn't, Siddall will have spent two stints in federal housing policy, one diagnosing the problem, one failing to fix it.
