Evan Siddall Returns to Federal Housing as Build Canada Homes Chair
The federal government has $15 billion and a mandate to bypass the housing bottlenecks that provincial and municipal governments can't or won't solve. To run it, Ottawa picked the person who spent seven years warning that the mortgage market was overheating and that affordability had become a structural crisis rather than a pricing problem.
Evan Siddall led the Canada Mortgage and Housing Corporation from 2014 to 2021. During that stretch, he pushed through the mortgage stress test, publicly questioned whether Canadians were borrowing too much, and reshaped CMHC from a passive insurer into an institution with a housing-first social mandate. He wasn't popular with real estate boards. He was respected by economists and risk managers. Now he's been appointed inaugural chair of Build Canada Homes, the Crown corporation created to build middle-income and social housing on federal land using federal financing.
The appointment signals intent. Build Canada Homes is not a grant program or a loan fund. It's a developer. The corporation holds the authority to acquire sites, manage construction, and operate rental buildings directly, functions the federal government hasn't performed at scale since the 1990s. Siddall's background is investment banking and stress-testing trillion-dollar portfolios. Placing him at the helm suggests the government expects Build Canada Homes to behave more like a disciplined institutional investor than a public works department.
What the mandate actually requires
The corporation's task is speed and volume. CMHC's own supply gap analysis estimates Canada needs 3.87 million additional units by 2031 to restore affordability. The private sector isn't building at that pace, partly because land assembly is slow, zoning approvals take years, and financing for rental projects is scarce when construction costs are this high. Build Canada Homes is meant to solve all three at once by leveraging federal land, streamlined approvals, and balance-sheet lending that doesn't require immediate profit.
That sounds efficient on paper. In practice, it requires threading a needle: building fast enough to matter politically, but structuring deals carefully enough that the projects remain solvent over 30-year holding periods. Siddall spent his CMHC tenure explaining that bad underwriting always catches up to you. If Build Canada Homes becomes a subsidy engine that builds units no one can afford to operate or maintain, it will fail in the second act even if it succeeds in the first.
The CMHC relationship will define success
Build Canada Homes is not replacing CMHC. The two entities will need to work in tandem, CMHC still controls mortgage insurance, housing research, and most federal housing program delivery. The risk is duplication. The opportunity is division of labor: CMHC handles market-rate insurance and policy design, Build Canada Homes handles direct construction where the market has stalled.
Siddall's institutional knowledge matters here. He knows which CMHC programs worked, which ones became political theater, and where the bottlenecks actually are. If Build Canada Homes ends up replicating existing programs under a different logo, that's a governance failure. If it complements CMHC by taking on the high-risk, low-return projects that private capital won't touch, then the structure justifies itself.
The deeper test isn't whether the corporation builds units. It's whether those units pencil out. A Crown developer operating in an inflationary environment with labor shortages and permitting delays can easily become a cost-overrun factory. Siddall's job is to prove the model works without proving that only the state can do it, because if private capital sees Build Canada Homes and decides federal subsidy is now the baseline, the program undermines its own goal.
He returns to federal housing during the hardest part: when the politics demand visible progress and the economics demand patience.
