How are mortgage rates determined in Ontario?
What affects fixed mortgage rates?
Fixed mortgage rates are primarily driven by the bond market, specifically Government of Canada bond yields, since lenders use bonds to fund fixed-rate mortgages. When bond yields rise, fixed rates tend to follow; when they fall, fixed rates usually ease too.

What affects variable mortgage rates?
Variable mortgage rates are tied to each lender’s prime rate, which moves in lockstep with the Bank of Canada’s overnight rate (aka the “key interest rate” or “policy rate”). A variable rate is typically quoted as prime minus a discount (e.g., prime minus 0.75%).
Tariffs, tension and the effect on mortgage rates
This may surprise you: but your fixed mortgage rates can be affected by conflict overseas. Fixed rates are tied to bond yields, and bond yields respond to global instability. In this case, tension in the Middle East and disruption to a key shipping route have pushed energy prices up and rattled markets. Never mind the latest tariffs and inflation threats that will likely have an effect as well.
Even without a Bank of Canada rate hike, banks are pricing in extra caution right now: call it an “uncertainty premium.”
While our fixed rates have remained stable for a few months, the bigger pieces at play could have an affect at the next BoC meeting in September.
And that will have a direct impact on your mortgage renewal.
Other factors that affect mortgage rates in Ontario and Canada
The Bank of Canada’s policy rate is set at scheduled meetings throughout the year based on inflation, employment, and overall economic growth. This is the single biggest driver of variable rates and an indirect driver of fixed rates too.
Inflation is a core input for the Bank of Canada: when inflation runs hot, the central bank tends to raise (or hold) rates to cool spending; when inflation eases, it has more room to cut.
Employment and GDP growth feed into the Bank of Canada’s decisions. A slowing economy nudges toward rate cuts, whereas a strong economy can support rate holds or hikes.
Lender competition and risk appetite also play a role at the individual level — discounts off prime, and how aggressively a lender prices fixed rates, can vary based on their own funding costs and how much mortgage business they want to write. Housing market conditions feed back into the cycle too — a cooling housing market can factor into the Bank of Canada’s broader growth outlook, indirectly influencing future rate decisions.
Global events have an effect on mortgage renewals in Canada:
Global bond markets and geopolitical events (wars, trade disputes, supply chain shocks) can move Canadian bond yields even without any domestic policy change, since investors reprice risk across markets. This is what pushes fixed rates around independently of the Bank of Canada.
- War and conflict abroad can spike energy prices and rattle bond markets, and since fixed mortgage rates track bond yields, tension overseas can push fixed rates up even without any change from the Bank of Canada
- Trade disputes and tariffs create economic uncertainty, which lenders price into their rates as a kind of “risk premium,” the less certain the outlook, the more cushion banks build in
- Shipping and supply chain disruptions (like a blocked trade route) can drive up the cost of goods and inflation, which in turn pressures the Bank of Canada toward higher rates to keep prices in check
- Global recession fears or growth slowdowns can have the opposite effect, pulling variable rates down as the Bank of Canada looks to stimulate the economy
- Central bank decisions in other countries (especially the U.S. Federal Reserve) can indirectly move Canadian bond yields and fixed rates, since capital markets are closely linked across borders
- Net effect for renewers: even a stable domestic economy doesn’t guarantee stable rates. Global instability can show up in a mortgage renewal quote with little warning, which is exactly why locking in a rate hold early gives some protection either way
If you’re renewing your mortgage in 6-12 months:
Rate Holds
Rate holds are underused. If you’re open to switching lenders, you can typically lock in a rate hold for up to 120 days.
And if rates drop before your renewal date, you get the lower one. Staying with your current bank usually limits this to about 30 days out.
