Siddall’s Return Signals a New Phase for Canada’s Non-Market Housing Push
Governance decides whether ambitious housing mandates turn into shovels in the ground or stall in committee rooms. That is why the appointment of Evan Siddall as inaugural chair of Build Canada Homes matters more than a routine leadership announcement. It tells us Ottawa understands that scaling non-market housing is fundamentally a development problem, one that requires someone who has already built the institutional machinery to move federal housing policy from paper to product.
Build Canada Homes became a Crown corporation in June, following royal assent of the Build Canada Homes Act, after launching in September 2025 as a special operating agency within Housing, Infrastructure and Communities Canada. Under transitional provisions, Siddall will hold the board’s powers until at least eight directors are appointed, effectively running the agency’s early strategic direction alone. For a development watcher, that concentration of authority in a single, experienced hand is a signal of intent rather than a governance gap.
The numbers behind this agency are what should draw attention from anyone tracking housing supply pipelines. Build Canada Homes has already committed to nearly 17,000 units across 17 partnerships, with more than 1,900 homes under construction. That is not a pilot program. That is a national-scale development platform being assembled through contributions, loans and loan guarantees, aimed squarely at non-market housing, the segment private capital consistently underbuilds. The agency’s added mandate to encourage Canadian technology, workers and building materials also points toward a longer strategy of building domestic capacity, not just units.
Siddall’s track record makes him a credible steward for that scale of ambition. As CMHC’s chief executive from 2014 to 2021, he helped shape more than 30 housing programs and a federal-provincial-territorial housing accord, including the National Housing Co-Investment Fund and the Rental Construction Financing Initiative. He also built a reputation as a disciplined voice on mortgage risk, defending stress testing and resisting demand-side stimulus he believed would erode affordability. That is the instinct of someone who treats housing supply as infrastructure planning, not a short term political win.
Evan Siddall’s appointment will provide Build Canada Homes the governance foundations needed to advance its mandate.
That line from CEO Ana Bailão gets at the real story here. Ambitious unit targets mean little without governance capable of managing land assembly, partnership structuring, financing terms and delivery timelines at national scale. Siddall’s time leading the Alberta Investment Management Corporation and his recent role as vice-chair of BMO Capital Markets add a capital markets fluency that will matter as the agency negotiates financing for projects across dozens of municipalities with very different land economics.
For those of us watching how Canadian cities intensify and diversify their housing stock, the appointment is worth tracking as a leading indicator. If Build Canada Homes fills its board quickly and Siddall’s governance model holds, expect the agency’s development pipeline, and its influence on how non-market housing gets financed and built across the country, to expand well beyond its current 17 partnerships.
