How Often Do Mortgage Rates Change in Alberta?
Short answer
Fixed mortgage rates can change daily — sometimes multiple times — as bond yields move. Variable rates change when lenders adjust prime, usually after Bank of Canada policy announcements (eight times per year) but occasionally between meetings. Your locked contract rate does not change during your term regardless of market moves.
The plain-English version
Fixed-rate mortgages are repriced continuously based on funding costs in bond markets. A lender's rate sheet for a 5-year fixed might update several times in a volatile week. That is why a quote on Monday may differ by Friday. A rate hold protects you from increases during the hold period, not from market reality over a long shopping timeline.
Variable rates move less frequently but can still shift on any day if a lender changes prime — often in response to Bank of Canada decisions. Between policy dates, prime usually stays stable. Once you close, your variable rate adjusts with prime but your spread stays fixed for the term.
Alberta-specific considerations
- Alberta buyers in active spring markets should get rate holds early — daily fixed-rate moves can outpace a long home search.
- New-build purchases with 6–12 month closings need longer rate holds or extension policies — confirm terms upfront.
- Renewal shoppers face the same daily repricing — start comparing 120 days before maturity when offers arrive.
Example scenario
On a volatile week, 5-year fixed rates at one lender move from 5.19% on Monday to 5.34% on Thursday as bond yields rise 0.15%. A buyer who delayed locking a hold loses the lower rate. A buyer with a 120-day hold at 5.19% keeps that rate if they close within the hold period and meet all conditions.
Common mistakes to avoid
- Assuming a verbal rate quote from last month is still valid.
- Waiting for rates to drop further without a hold while actively shopping — markets move both ways.
- Thinking variable rates only change eight times a year — lenders can adjust prime between Bank of Canada dates.
- Ignoring that your existing mortgage rate is fixed for the term — market changes only affect new borrowing or renewal.
