Key Takeaway

Fixed mortgage rates in Canada do not directly follow the Bank of Canada’s policy rate. Instead, fixed rates track the yields on Government of Canada bonds, particularly the five-year bond. When the BoC announces a rate change, your fixed mortgage rate may have already moved weeks earlier, moved in the opposite direction, or not moved at all. Variable-rate mortgages, by contrast, are directly tied to the BoC policy rate through the prime rate.

How the Bank of Canada Rate Works

The Bank of Canada sets the overnight rate, also known as the policy interest rate, which is the rate at which major financial institutions borrow and lend one-day funds among themselves. According to the Bank of Canada, this rate influences the prime rate that Canadian banks charge their most creditworthy customers. Variable-rate mortgages and home equity lines of credit (HELOCs) move in lockstep with prime: when the BoC raises its rate by 0.25 percentage points, prime typically rises by the same amount within days, and your variable rate follows.

This direct relationship makes variable rates predictable in direction, if not in timing. A BoC rate cut means lower variable mortgage payments; a rate hike means higher payments.

What Drives Fixed Mortgage Rates

Fixed mortgage rates, however, are priced against the bond market. Canadian lenders look at the yield on Government of Canada bonds when setting fixed rates, with the five-year bond yield serving as the benchmark for the popular five-year fixed mortgage. As covered in foundational finance texts such as Principles of Finance, bond yields reflect the market’s collective expectation of future inflation, economic growth, and central bank policy over the life of the bond.

Bond traders buy and sell based on what they think will happen months or years ahead. If the market expects the Bank of Canada to cut rates six months from now due to a slowing economy, bond yields fall today, and fixed mortgage rates drop before the BoC makes any move. Conversely, if inflation data suggests future rate hikes, bond yields and fixed rates can rise even while the BoC holds its policy rate steady.

Lenders add a spread on top of the bond yield to cover their costs, risk, and profit margin. The spread varies by lender, mortgage term, and competitive conditions, but the anchor is always the bond market, not the overnight rate.

Why the Disconnect Happens

The mismatch occurs because the two rates serve different purposes and respond to different signals. The BoC policy rate is a tool for managing short-term liquidity and inflation today. Bond yields are a forecast, pricing in what investors believe the BoC and the economy will do over the next several years.

In practical terms, this means fixed and variable rates can move in opposite directions. During the early months of 2023, for example, the BoC continued hiking its policy rate to combat inflation, pushing variable rates higher. At the same time, bond yields fell as markets anticipated a future recession and eventual rate cuts, and some fixed mortgage rates declined.

According to the Financial Consumer Agency of Canada, Canadian borrowers choosing between fixed and variable rates should understand that each mortgage type reacts to different economic indicators. A fixed rate locks in today’s bond market expectations; a variable rate floats with the BoC’s current policy stance.

What This Means for Your Mortgage Decision

If you are shopping for a mortgage or approaching renewal, do not assume a BoC rate announcement will automatically move fixed rates in the same direction or magnitude. Check current Government of Canada five-year bond yields, which are published daily and widely available on financial news sites, to get a sense of where fixed rates are headed.

When comparing fixed versus variable, consider your risk tolerance and the economic outlook. Variable rates offer immediate savings when the BoC cuts, but they expose you to payment increases if the BoC raises rates. Fixed rates protect you from payment shock but lock you into the bond market’s current forecast, which may or may not prove accurate.

Mortgage rates vary by lender, product, and your financial profile. As of October 2026, rates change frequently. Verify current terms with a licensed mortgage broker or your financial institution before deciding, and confirm prepayment options and penalties under each scenario. Mortgage decisions in Canada are also subject to the OSFI mortgage stress test, which requires you to qualify at a rate higher than your contract rate regardless of whether you choose fixed or variable.
