What actually sets the interest rate on a loan
The rate you are quoted is a price for risk, set by the lender that will hold the loan. Benchmarks sit underneath it: the Bank of Canada publishes the policy interest rate, the prime rate, conventional mortgage rates and Government of Canada benchmark bond yields. Those are benchmarks, not offers, and no lender is obliged to lend at them.
On top of that, lending in Canada is licensed provincially, so the regulator and the rules differ depending on where a lender operates. That is why two lenders can quote you very different numbers for the same request — and why the borrower-side factors below are the ones you can actually work on.
File strength: what your credit file says about you
Canada has two national credit reporting bureaus, Equifax Canada and TransUnion Canada, and each keeps its own file on you. Lenders may look at one or both. What they see is a record of how you have handled credit, not a single score you can argue with.
Two items weigh on a file for a defined period. A consumer proposal stays on a credit report for 3 years after completion, or 6 years from filing, whichever comes first. A first bankruptcy stays on a credit report for 6 years after discharge. Only a licensed insolvency trustee can administer a consumer proposal or bankruptcy, so any other party offering to repair that history is not the right place to start.
File strength also includes the ordinary parts: whether your income is steady, how long you have held your accounts, and how much of your income is already promised to other debts. For mortgages at federally regulated lenders, total debt service ratio ceilings sit at about 44%, and an uninsured mortgage is qualified at the greater of the contract rate plus 2 percentage points and 5.25%, under OSFI Guideline B-20. Those rules mean the rate you are approved at and the rate you are qualified at are not always the same number.
Security: what the lender can fall back on
An unsecured loan has nothing behind it but your promise to pay, so its price reflects the lender's whole exposure to you. A secured loan or a home equity line of credit is backed by an asset, which reduces the lender's loss if things go wrong. At federally regulated lenders, a home equity line of credit is generally limited to 65% of appraised property value, with total secured lending usually capped at 80%.
Lower quoted rates on secured borrowing are common, but the trade is real: you are putting an asset at risk, and that asset can be your home. Whether that trade makes sense depends on your circumstances, and for a decision of that size it is worth getting regulated professional advice rather than working from a general guide.
Repayment term and product structure
Term and structure change both the rate and the total cost. A shorter repayment term often comes with a lower rate on a fixed product, because the lender is exposed for less time, but the payment is higher. A longer term lowers the payment and raises the total interest you pay across the life of the loan. Neither is automatically better.
Mortgages carry a quirk worth knowing: Canadian fixed-rate mortgages are compounded semi-annually by law, so the advertised rate is not the same as the effective annual rate. Personal loan pricing usually works differently, and the Financial Consumer Agency of Canada's personal loans page walks through what a loan agreement should tell you, including the cost of borrowing.
Comparing the routes: what each one asks of you
The table describes structures and constraints, not offers. No row is a rate anyone can promise you.
| Route | What backs it | What mainly moves the rate | Main structural limit |
|---|---|---|---|
| Unsecured personal loan | Nothing but your promise to pay | Your credit file, income stability and existing debt load | No asset at risk, but pricing reflects the lender's full exposure to you |
| Secured loan or home equity line of credit | An asset, often your home | Appraised value, loan-to-value and your file | At federally regulated lenders, a HELOC is generally limited to 65% of appraised value, with total secured lending usually capped at 80% |
| Mortgage, fixed rate | The property | Contract rate, term, down payment and how you qualify | Qualification uses the greater of the contract rate plus 2 points and 5.25%; total debt service ceiling of about 44%; semi-annual compounding by law |
| Payday loan | A post-dated cheque or pre-authorized debit | A flat cost per $100 advanced rather than a quoted annual rate | Generally up to $1,500 for a term of 62 days or less; where a province licenses payday lending, the federal cap is $14 per $100 advanced, and some provinces set a lower cap that applies instead |
| Existing credit line or balance transfer | Your existing limit and relationship | Terms already attached to that account | You are limited by the account's own terms and whatever offers that lender makes to you |
An existing relationship, and shopping around
A lender you already deal with holds information other lenders do not: how you have handled a chequing account, a previous loan or a mortgage. That internal history sometimes gives a lender room to price differently for you than for a stranger with a similar file. It is not a rule and it is not a promise, but it is a reason to ask before you assume.
Shopping around is the other lever. Compare the same amount, the same term and the same payment frequency across several lenders so the quotes are genuinely comparable, and ask for the total cost of borrowing rather than the headline rate alone. Ask each lender whether it is running a pre-qualification or a full application, because the two are not the same for your file. The credit bureaus do not publish their scoring models in full, so treat any confident claim about exactly how much one inquiry costs you as an estimate rather than a rule.
It is also worth asking who regulates the lender. Complaints about federally regulated financial institutions go to the Financial Consumer Agency of Canada, while provinces license and supervise most other lenders. Knowing which side a lender sits on tells you where a problem would actually be heard.
What you cannot control
Some of the number is not yours to move. The Criminal Code sets the criminal rate of interest at 35% per year under section 347, which is a ceiling rather than a benchmark anyone lends at. Payday lending sits in its own framework: where a province operates a licensed payday lending regime, the federal Payday Lending Regulations (SOR/2024-114) cap the cost of borrowing at $14 per $100 advanced, and some provinces set a cap lower than that, in which case the lower cap applies. Quebec does not license payday lending, which effectively prohibits the model there.
The Bank of Canada's policy rate, and the market rates that follow it, are set far away from your application, and you cannot negotiate those. What you can do is present a better file, choose a structure you can live with, and refuse to treat the first quote as final.
A checklist before you apply
- Get your reports from Equifax Canada and TransUnion Canada and correct anything that is wrong before a lender sees it.
- Write down your real income, your fixed obligations, and the payment you could still handle if your income dropped.
- Decide in advance whether you are willing to secure the loan, and understand what happens to the asset if you cannot pay.
- Collect quotes for the same amount, term and payment frequency so the comparison means something.
- Ask each lender whether the quote is a pre-qualification or a full application.
- Ask for the total cost of borrowing in writing, not just the rate.
- Confirm who regulates the lender, so you know where a complaint would go.
Where loanmoose.ca fits
loanmoose.ca is not a lender. It does not make loans, set rates or make credit decisions. It is a matching and comparison service: you describe what you need, and it connects you with lenders and licensed professionals who can quote you directly. Every rate in this guide is a factor to discuss with a lender, not something this page can offer you.
If you are searching under terms like low interest loans Canada, low interest personal loans or cheap interest loans, the honest version of the answer is that those phrases describe outcomes, not products. The lowest rates are only available to the most qualified applicants. Your job is to become a better applicant and to compare properly; the lender's job is to price you. The right answer depends on your circumstances, and for anything significant, on regulated professional advice.
