The Mechanisms
Five Policy Drivers of Unaffordability
CMHC Mortgage Insurance — Socialised Risk, Privatised Profit
CMHC insures over $500 billion in Canadian mortgages. This insurance allows lenders to extend credit with lower down payments — increasing the number of buyers who can enter the market. More buyers competing for limited supply drives prices up. The risk of default is borne by CMHC (and ultimately taxpayers), while the profits from rising property values accrue to homeowners and financial institutions. This is documented public policy that inflates demand without proportionally increasing supply. CMHC acknowledges that Canada needs 3.9 million additional housing units by 2031 to restore affordability — while simultaneously providing the mortgage insurance that fuels demand.
REIT Tax Treatment — Institutional Ownership Incentivised
Real Estate Investment Trusts (REITs) receive preferential tax treatment under Canadian tax law. REITs that distribute income to unitholders are not taxed at the entity level — meaning institutional ownership of residential property receives more favourable tax treatment than many small business structures. Canadian REITs own hundreds of thousands of residential rental units. Institutional ownership of rental housing creates a financial incentive to maximise rental income and property values — which directly conflicts with tenant affordability. The tax policy that enables this is a federal government decision.
Supply Constraints — Zoning and Construction Barriers
Municipal zoning restrictions limit density in many Canadian urban areas. Single-family zoning reserves large portions of major cities for low-density housing, limiting the construction of apartments and condominiums that could increase supply. Construction labour shortages, material costs, and development approval timelines further constrain supply. The federal government set a target of 3.87 million new homes by 2031 but construction capacity has not kept pace. The result: demand increases (through population growth, immigration, and CMHC-enabled credit) faster than supply can respond, driving prices continuously upward.
Immigration Targets vs. Housing Construction
Canada's immigration targets — exceeding 400,000 permanent residents annually plus temporary foreign workers and international students — create documented housing demand that outpaces construction. CMHC's own analysis identifies the demand-supply gap as a primary driver of unaffordability. Immigration policy is set by the federal government. Housing construction is constrained by municipal zoning, provincial building codes, and labour availability. The two policy areas operate independently, creating a structural mismatch between population growth and housing supply.
Capital Gains Treatment — Housing as Tax-Free Investment
The principal residence capital gains exemption means that gains on a primary home are tax-free — regardless of the amount. This creates a powerful incentive to invest in housing over other asset classes. Combined with CMHC-insured leverage (minimum 5% down payment), Canadian housing offers tax-free leveraged returns that no other investment vehicle matches. The result: housing functions as Canada's primary tax-advantaged investment vehicle, driving demand from investors as well as shelter-seekers. This tax policy is a federal government decision that directly contributes to unaffordability.
The Architecture of Unaffordability
Every mechanism driving housing unaffordability is a government policy decision. CMHC insurance: federal. REIT tax treatment: federal. Immigration targets: federal. Capital gains exemption: federal. The government controls all the inputs.
