Canada’s fixed mortgage market has a second policy lever beyond the Bank of Canada: Ottawa is buying up to C$30 billion of Canada Mortgage Bonds in 2026. (bankofcanada.ca) Canada Mortgage Bonds are securities backed by pools of insured mortgages. Canada Mortgage and Housing Corp. says approved lenders bundle eligible insured loans, and investors buy the bonds to fund residential mortgages. (cmhc-schl.gc.ca) The Bank of Canada said on Jan. 29, 2026 that the federal government would participate in all fixed-rate Canada Mortgage Bond syndications proposed for 2026, across five-year and 10-year tenors. The purchases are capped at C$30 billion for the calendar year and exclude floating-rate bonds. (bankofcanada.ca) That matters because five-year fixed mortgages in Canada are commonly priced off bond-market funding costs, not directly off the overnight rate. Canada Mortgage Bonds are one of the main wholesale funding channels for insured mortgage lending. (cmhc-schl.gc.ca, bankofcanada.ca) When the government buys a large share of new issuance, it can support demand for those bonds and influence the spread over Government of Canada bonds that lenders watch. CMHC says Canada Mortgage Bonds carry the full faith and credit of Canada and are issued in benchmark five-year and 10-year terms. (cmhc-schl.gc.ca) The program has grown as Ottawa has tied housing finance more closely to housing supply policy. Budget 2024 raised the annual Canada Mortgage Bond issuance limit from C$40 billion to up to C$60 billion, and Budget 2025 raised it again to C$80 billion starting in 2026. (budget.canada.ca, budget.canada.ca) CMHC’s investor fact sheet says the 2026 structure leaves up to C$30 billion for government purchases and the rest for private buyers. The agency said the program had about C$300.3 billion outstanding as of Feb. 28, 2026. (cmhc-schl.gc.ca) The Bank of Canada’s purchase page shows the government had already bought C$7.5 billion of 2026 fixed-rate issuance by March 13, 2026: C$2.25 billion in a 10-year deal on Feb. 12 and C$5.25 billion in a five-year deal on March 13. (bankofcanada.ca) The Parliamentary Budget Officer said in a 2025 report that Ottawa had bought C$50.8 billion of Canada Mortgage Bonds between February 2024 and Sept. 30, 2025, equal to 48.1% of total issuance over that period. The office also noted that Canada Mortgage Bonds have historically yielded more than Government of Canada bonds of the same maturity. (pbo-dpb.ca) The immediate question is not whether the program exists; it does. The question is how far sustained C$30 billion annual buying compresses funding spreads, and how much of that shows up in the fixed mortgage rates lenders post to borrowers.
