Your mortgage rate is the single biggest factor in how much your home costs you. Even a small rate difference adds up to tens of thousands of dollars over the life of the mortgage. Here is how to ensure you get the best rate possible.
What determines your mortgage rate
| Factor | Impact on Rate |
|---|---|
| Bank of Canada policy rate | Sets the baseline for all rates |
| Bond yields (5-year) | Directly affects fixed rates |
| Your credit score | Higher score = lower rate |
| Down payment size | 20%+ removes insurance, may lower rate |
| Property type | Single family homes get the best rates |
| Amortization period | 25 years or less gets better rates |
| Mortgage type | Insured mortgages often have lower rates |
| Lender competition | More quotes = more negotiating power |
Step 1: Optimize your credit score
Your credit score directly affects the rate you qualify for.
| Credit Score | Typical Rate Impact |
|---|---|
| 760+ | Best available rates |
| 720-759 | Near-best rates |
| 680-719 | Standard rates |
| 650-679 | Higher rates |
| Below 650 | May need alternative lenders (much higher rates) |
Before applying for a mortgage, check your score and work on improvements if needed. See our guide on how to improve your credit score.
Step 2: Use a mortgage broker
Mortgage brokers compare rates from 30+ lenders — banks, credit unions, monoline lenders, and alternative lenders. They frequently access rates lower than what banks offer directly.
Why use a broker:
- Free service (paid by the lender)
- Access to lenders you cannot go to directly
- Knowledge of promotional rates and special offers
- Handle paperwork and negotiate on your behalf
Top mortgage broker networks:
- CanWise (online, part of RATESDOTCA)
- True North Mortgage
- Nesto
- Your local independent broker
Step 3: Get at least 3-5 quotes
Never accept the first rate offered. Even if you prefer your bank, get competing quotes.
| Source | Pros | Cons |
|---|---|---|
| Big 5 banks | Branch access, bundled services | Often higher posted rates |
| Credit unions | Competitive rates, local service | Limited product selection |
| Monoline lenders | Lowest rates, mortgage-focused | No branch access |
| Mortgage broker | Compares 30+ lenders for you | No direct servicing |
| Online lenders | Low overhead = lower rates | Limited in-person support |
Step 4: Negotiate
Banks have discretion to lower rates. Use competing offers as leverage.
Negotiation script:
“I have been approved at [competitor rate] with [lender name]. I would prefer to work with your bank, but I need you to match or beat that rate. What can you do?”
Tips:
- Always have a written competing offer
- Negotiate at the end of the month (advisors have quotas)
- Ask about rate holds (lock in a rate for 90-120 days while shopping)
- Ask about cash-back offers or fee waivers as additional negotiating points
Step 5: Consider your mortgage structure
| Choice | Impact on Rate |
|---|---|
| Fixed rate | Usually higher than variable; payment certainty |
| Variable rate | Usually lower; payments fluctuate with prime |
| 5-year term | Most common; best rate selection |
| Shorter term (1-3 years) | Sometimes lower; renew sooner |
| 25-year amortization | Standard; better rates than 30 years |
| 30-year amortization | Higher rates; lower monthly payment |
| Insured (< 20% down) | Often lower rates (less risk to lender) |
| Uninsured (20%+ down) | Slightly higher rates but no insurance premium |
Step 6: Lock in your rate
Once you find a good rate, ask for a rate hold:
- Most lenders offer 90 to 120 day rate holds
- If rates drop before closing, many lenders will give you the lower rate
- If rates rise, you keep the locked rate
- Rate holds are free and non-binding
The cost of not shopping around
On a $500,000 mortgage, 25-year amortization:
| Rate | Monthly Payment | Total Interest (25 years) |
|---|---|---|
| 4.50% | $2,756 | $326,750 |
| 4.75% | $2,826 | $347,800 |
| 5.00% | $2,898 | $369,300 |
| 5.25% | $2,970 | $391,060 |
| 5.50% | $3,044 | $413,200 |
The difference between 4.50% and 5.50% is $288/month or $86,450 over 25 years.

Timing your mortgage
While you cannot perfectly time the market, understanding rate trends helps:
- Fixed rates follow the 5-year Government of Canada bond yield
- Variable rates follow the Bank of Canada overnight rate
- Check the current prime rate for variable rate benchmarks
- Consider rate direction when choosing fixed vs variable
How to get the best mortgage rate in Canada
1. Use a mortgage broker. Brokers access 50–100+ lenders and are paid by lenders, not you. They often find rates 0.1–0.5% below what banks quote directly. The best rates in Canada are rarely advertised by the Big 5.
2. Compare online lenders. nesto, Homewise, and Butler Mortgage consistently offer some of Canada’’s lowest rates. Get a quote from at least one online lender before accepting a bank offer.
3. Leverage competing offers. Get 2–3 competing rate quotes and present them to your preferred lender. Most lenders (including major banks) have discretion to beat a competing offer.
4. Increase your down payment. Moving from 5% to 10% down reduces your LTV and can improve rate offers. Moving to 20%+ eliminates CMHC insurance and may access lower rates from some lenders.
5. Improve your credit score. Scores above 720 typically access the best rate tiers. Pay down revolving credit, eliminate missed payments, and avoid applying for new credit 6 months before mortgage applications.
Frequently asked questions
How much difference does 0.5% make on a Canadian mortgage? On a $500,000 mortgage (25-year amortization):
- At 5.0%: $2,908/month; total interest over 25 years = $372,400
- At 5.5%: $3,048/month; total interest over 25 years = $414,400
The difference: $140/month and $42,000 in total interest. Rate shopping matters significantly.
Should I get a pre-approval or a rate hold first? A pre-approval includes a credit check and income verification — it holds a rate for 90–120 days and gives sellers confidence. A rate hold (rate lock without full qualification) is simpler but provides less certainty. In a rising rate environment, pre-approvals are worth the credit inquiry. In stable or declining rates, either works.
