Search for how to improve a credit score in Canada and you will find the same picture on almost every page: a pie chart splitting your score into neat slices. Payment history thirty-five per cent. Amounts owed thirty per cent. Length of history fifteen. And so on, identical from site to site.
Those numbers are not Canadian. They come from American scoring documentation and get reproduced here without anyone checking. Canada's federal consumer agency states the position directly: credit bureaus and lenders use different formulas to calculate your score, and they do not share the exact details.
So this article contains no percentages. What it contains instead is the list of factors the federal agency does name, in the order it ranks them, and what each one means for somebody planning a mortgage application. That is less satisfying than a pie chart and considerably more useful.
What a Canadian credit score is
Scores usually run from three hundred to nine hundred, and higher is better. Two main credit bureaus operate in Canada, Equifax and TransUnion, and they only collect information about your credit activity in Canada. Your reports are updated at least once a month, which sets the pace of everything below: changes show up in weeks, not days.
One more thing worth knowing before you check anything. The score you see may differ from the score a lender sees, because a lender may give more weight to certain information when they calculate their own. A number from a free app is a direction of travel, not the figure your lender will act on.
And the most common worry can be settled in one sentence: checking your own credit report or score does not affect your score. More on why in the inquiries section below.
Payment history, which the federal agency ranks first
Your payment history shows how often you pay your bills on time, and the consumer agency calls it the most important part of your credit score. Not one factor among several. The most important part.
What it asks for is unglamorous:
- Always make your payments on time.
- If you cannot pay the full amount, make at least the minimum payment.
- Contact the lender right away if you think you will have trouble paying.
- Do not skip a payment even if you are disputing a charge.
That last one catches people. A disputed charge feels like a reason to withhold payment, and the dispute is a separate process from the payment record. Withholding registers as a missed payment regardless of whether you were right about the charge.
The practical fix most people overlook is automation. Many financial institutions can send an electronic alert when a payment is due or when available credit falls below a set amount. Setting those up takes a few minutes once and removes the failure mode entirely.
Credit utilization, and the part that surprises people
Your credit utilization rate, also called credit use, is how much credit you use compared to your credit limit. The federal guidance is to try to use less than thirty per cent of your total credit limit. Their example: a card with a five thousand dollar limit, normally used to a thousand dollars, is running at twenty per cent.
Here is the part that catches careful people out. Lenders look at your utilization rate to judge how you manage available credit, and if you regularly use a lot of it they may see you as higher risk. In the agency's own framing, this can happen even when you pay off your debts in full every month. Low credit use shows lenders you do not rely too heavily on borrowed money.
Read that again if you are the sort of person who puts everything on one card for the points and clears it every month. You are managing your money well and your utilization rate does not know that. It sees a card running near its limit each cycle.
Three things follow:
- Do not go over your credit limit.
- Aim to have a higher credit limit and use only a small portion of it.
- Keep your monthly utilization rate low even if you pay the full balance.
If you run everything through one card, the cheapest fix is spreading the same spending across two, or asking for a limit increase you do not intend to use.
The length of your history, and the balance transfer trap
Your credit history includes how long you have had credit accounts and whether you keep them active. Lenders want to see a long and stable history, which is the one factor you cannot accelerate. It only accrues.
Which is why the most common self-inflicted damage happens here. Suppose you open a new credit card to transfer a balance at a better rate. That new card counts as a new account, which lowers the average age of your accounts and can lower your score. Then you close the old card, because keeping it feels untidy. Closing it can hurt more than the opening did, and for two reasons at once: you lose the older credit history, and you reduce your available credit, which pushes your utilization rate up on everything that remains.
The consumer agency's own guidance is to consider keeping an old account open when it has no annual fee, it is easy for you to manage, and you can use it occasionally to keep it active. A dormant no-fee card with a small recurring charge on it is doing quiet work for you.
The obvious exception: if an old card carries a fee you cannot justify, or if keeping it available is a genuine risk to your spending, close it. A score is not worth a debt problem.
Inquiries, hard and soft
When a lender checks your credit report, the bureau records the inquiry. There are two kinds and the difference matters more than most people realise.
| Hard inquiries | Soft inquiries | |
|---|---|---|
| Where they show | On your credit report, visible to anyone who views it | Only on the version of the report you can see |
| Effect on score | They affect it | They do not affect it |
| Typical examples | Credit card applications, mortgage applications, credit and loan applications, some rental applications, some employment applications | Requesting your own credit report; a company you already have an account with updating its records, such as an internet or telephone provider |
So checking your own report is a soft inquiry and costs you nothing. Do it before you start a mortgage application rather than after, because a reporting error found in March is a solved problem and the same error found the week of your offer is a crisis.
Applying for credit occasionally is normal. Too many inquiries too close together can make lenders think you are urgently seeking credit or spending beyond your means. The guidance is to apply only when you need to, and to avoid sending multiple applications at once.
The exception that makes rate shopping safe
There is a carve-out written specifically for people doing what you are about to do. When shopping for a car loan or a mortgage, get quotes from different lenders within a two week period, and the credit bureaus treat those as a single inquiry.
This matters because the fear of damaging a score is the single most common reason buyers accept the first rate they are offered. It does not apply if you keep the shopping compressed. Gather your quotes inside two weeks and the whole exercise registers once. Spread the same quotes over two months and it does not.
That window is also why a broker application works the way it does: one conversation, one pull, several lenders. The mechanics of that are covered in the pre-approval guide.
Credit mix
Your credit history also includes the different types of credit you use. Having only one type of credit product may leave you with a lower score than having several managed well, such as a credit card, a car loan and a line of credit. The reasoning is straightforward: lenders want to see you can manage more than one type of credit responsibly.
The federal caveat attached to that guidance deserves equal billing. Only borrow money you are able to pay back, because taking on too much debt may harm your score. Opening a car loan you do not need in order to diversify your credit mix would be a genuinely bad trade, and worse, the new debt lands in your debt service ratios where it directly cuts how much mortgage you qualify for.
Who is allowed to check, and where that differs
In most provinces in Canada, a business or individual must have your consent before they can check your credit. Three provinces work differently: in Nova Scotia, Prince Edward Island and Saskatchewan, a business only has to tell you.
Worth knowing because a credit check is not only a lending event. Your report can affect whether you can rent a home or get a job, and your report shows inquiries from lenders who requested it in the last three years, so a string of applications stays visible for a while.
A realistic timeline
Because reports update at least monthly, nothing you do today shows up tomorrow. Here is how the factors actually sort by how fast they respond.
| What you change | Roughly how fast it shows |
|---|---|
| Paying down balances to cut utilization | Within a reporting cycle or two, once the lower balance is reported |
| Correcting an error on your report | Once the dispute resolves, so start early |
| Rebuilding payment history after a missed payment | Months of consistent on-time payments |
| Length of credit history | Not accelerable at all; only protectable by not closing old accounts |
Which gives you the order of operations if your application is a few months out. Pull your own report first, since it is free of score consequence and errors take the longest to fix. Then work on utilization, since it is the fastest-moving lever. Then leave your old accounts alone. Then stop opening anything new until you have closed on the house.
That last point is the one we repeat most often to clients, because the failure is so avoidable. Your credit is checked at application, and lenders commonly check again before closing. Financing a sofa between the two can change the answer.
What we do not tell people
We are asked constantly what score is needed to get a mortgage. We do not answer with a number, because there is no published federal minimum and every lender sets its own threshold against its own risk appetite. Anyone quoting you a specific figure as a rule is telling you about one lender's policy at one moment, or making it up.
What we can say is where your score sits in the decision. It is one of several inputs a lender uses to price your risk, alongside income stability, your down payment and the property. A stronger score improves the rate you are offered rather than simply deciding yes or no, and on a mortgage of any size that difference is measured in thousands of dollars a year. The arithmetic behind that is worked out in the interest rates guide.
The honest summary is unexciting. Pay on time, keep your usage well below your limits, leave your oldest accounts alone, compress your rate shopping into two weeks, and check your own report early enough that a mistake is an inconvenience rather than an emergency. There is no faster route, and anyone selling one is selling you something.
