Fixed vs variable in 2026
- Variable (~3.45% today) — cheaper now, payment moves with prime. You win if rates fall; you pay more if they rise. Penalties to break are usually 3 months' interest — much cheaper than fixed.
- Fixed (~4.14% today) — payment locked for the term. You pay a premium for certainty; breaking usually costs an interest-rate-differential penalty that can be large.
- 3-year fixed (~3.86%) — the middle path: cheaper than 5-year fixed, with a sooner chance to renegotiate.
Insured vs uninsured
Less than 20% down means CMHC insurance — and usually a lower rate, because the lender's risk is covered (4.14% best insured vs higher uninsured quotes). With 20%+ down you skip the insurance premium but typically pay 0.1–0.3 points more in rate. Run both scenarios through the Ontario affordability guide before deciding how much to put down.
How to actually get the best rate
- Never take the posted rate — discounts of 0.5+ points off posted are routine with negotiation or a broker.
- Get 3+ quotes — a bank, a broker, and a monoline lender. The spread between best and worst can exceed a full point.
- Improve what you can — bigger down payment, shorter amortization and stronger credit all widen your options.
- Time your lock — pre-approvals typically hold a rate 90–120 days; use the window, don't rush it.
- Read the penalty clause — the cheapest rate with a brutal IRD penalty can be the most expensive mortgage you ever sign.
Frequently asked questions
What is the best 5-year fixed mortgage rate in Ontario in October 2026?
The lowest published 5-year fixed rates are 4.14% (ATB Financial insured; Butler Mortgage broker quote) as of October 4, 2026, per NorthPeak's weekly tracker. Big-bank posted rates run higher, from about 4.59% to 5.14%.
What is the best 5-year variable mortgage rate in Canada right now?
About 3.45% as of early October 2026 (nesto and rates.ca published tables), with prime at 4.45%. Variable rates move with prime, so the discount you negotiate matters more than today's number.
Should I choose fixed or variable in 2026?
Variable (from 3.45%) is cheaper today but moves with prime; fixed (from 4.14%) costs more now but locks your payment for the term. With the Bank of Canada policy rate at 2.25%, borrowers betting on further cuts lean variable, while payment certainty favors fixed.
What is the difference between insured and uninsured mortgage rates?
Insured mortgages (less than 20% down, CMHC-insured) usually get lower rates because the lender's risk is covered. Uninsured mortgages (20%+ down) price slightly higher — the gap is typically 0.1 to 0.3 percentage points on comparable terms.
How often do mortgage rates change in Canada?
Lenders can reprice any day, but most movement follows Bank of Canada policy announcements and bond yields (for fixed rates). NorthPeak updates its tracker every Monday; check the current table before locking in.
