If you are finishing medical school in Canada, your debt load is probably larger than almost anyone else your age who isn’t pursuing the medical field. According to the Association of Faculties of Medicine of Canada (AFMC), roughly 35% of graduating students carry $120,000 or more in debt by the time they finish.
That number can feel heavy, especially during residency when your income is modest and your hours are long. The good news is that medical school debt in Canada is manageable with a clear, unhurried plan.
This article looks at what makes medical school debt in Canada its own category, the one debt type that is genuinely specific to physicians, and a simple habit-first sequence you can follow once training ends.
Why medical school debt in Canada is its own category
Most graduates carry a mix of debt. What sets medical trainees apart is the size of the balance and the type of credit behind it.
Tuition for medicine is high, training runs for years, and residency income arrives slowly. Many students also borrow to cover living costs, exam fees, and licensing steps along the way — including the application and interview costs that come with matching to residency through the Canadian Resident Matching Service (CaRMS). The result is a balance that can dwarf what other new graduates owe.
Just as important is the kind of debt involved. Physicians often rely on a specialized line of credit rather than a government student loan. That single difference changes how repayment works, so it is worth understanding before you build any plan.
The one debt that's genuinely physician-specific: the professional student line of credit
Government student aid, such as the Ontario Student Assistance Program (OSAP), is available to many students across programs. The professional student line of credit is different. It is offered specifically to students in fields like medicine, and it behaves nothing like a government loan.
How the professional student line of credit works
A professional student line of credit is revolving credit. You draw on it as you need money, up to a set limit, and you can borrow again as you repay.
The rate is tied to prime, usually at prime or slightly below. Prime has been 4.45% since October 2025, so a line of credit priced at prime or prime-minus currently sits at roughly 4% to 4.5%. It floats — when prime moves, your cost of borrowing moves with it.
A few features stand out:
Interest starts the day you draw on it, not when you graduate or finish residency.
You're charged interest only on what you've actually drawn, not on your full limit.
Limits are usually tied to your year of study and step up as you progress.
Repayment terms are set by your lender, not a government program — so there's no repayment assistance plan if your income comes in lower than you expected.
Why it behaves nothing like a government student loan
Government student loans come with borrower protections. A professional student line of credit comes with none of them.
With a government loan such as OSAP, repayment is cushioned in ways a line of credit never is. The federal portion of an OSAP loan is interest-free — automatically, with nothing to apply for. There’s also a six-month grace period before payments begin, and income-tested repayment help if you qualify.
But even those protections have limits worth knowing. The Ontario portion of an OSAP loan isn’t interest-free: it accrues at prime plus 1% and that interest keeps building through the six-month “grace period,” even though no payment is due yet. Repayment assistance isn’t an automatic safety net either; it’s income-tested, you have to apply, and you have to reapply every six months. A professional student line of credit offers none of this — no interest-free portion, no grace period, no assistance program to fall back on.
The key differences are worth stating plainly:
No interest relief: interest accrues immediately on what you draw.
No repayment assistance program: there is no government backstop if income is low.
Revolving credit: the balance can rise and fall as you borrow and repay.
Floating rate: your cost moves with prime rather than staying fixed.
None of this makes the line of credit a poor tool. It is often the practical way to fund training. It simply means the discipline is on you, because the safeguards attached to government loans are not there.
A simple habit-first sequence for new physicians
Once training ends and income begins to rise, it helps to move in order rather than trying to do everything at once. The sequence below is about building habits. At this stage, the win is the habit itself, not the size of any investment return.
First, clear high-interest consumer debt
Before anything else, look at high-interest consumer debt, such as credit card balances or unsecured personal loans. These rates are often far higher than the rate on a professional student line of credit.
Clearing this debt first is usually the most effective early move, because the interest you avoid is guaranteed. Paying off a balance charging 20% or more gives you a certain return that no investment can promise.
Focus your extra payments here until these balances are gone. Then move on to the next step with a cleaner slate.
Next, build line-of-credit discipline
With high-interest consumer debt handled, turn to your professional student line of credit. The goal now is discipline rather than speed.
Because the line of credit is revolving, it is easy to keep drawing on it out of habit. Try to separate the balance you already owe from new spending, so the total stops growing. Make consistent payments that at least cover the interest, and add more when your income allows.
Small, steady habits matter more than dramatic gestures here. A regular payment you can sustain beats an aggressive plan you abandon after two months.
Then, open your first registered account
Once your debt habits are steady, consider opening a first registered account. In Canada, common registered account types include the Registered Retirement Savings Plan (RRSP) and the Tax-Free Savings Account (TFSA), each with its own tax treatment and rules. Which to prioritize depends on your income now versus what you expect to earn later — a question worth raising with an advisor, especially while a resident’s income is still well below what it will be.
At this early stage, the amount you contribute matters less than starting the habit. Even a modest, automatic contribution builds the routine of paying your future self.
The point is to establish the account and the habit while your debt plan is already running. You are not aiming for large returns yet. You are proving to yourself that saving and investing can sit alongside debt repayment.
When to shift from paying down debt to investing
At some point, many physicians ask whether extra money should go toward debt or toward investing. That decision depends on your interest rate, your timeline, your tax situation, and your comfort with risk.
This article does not try to settle that question, because it deserves its own careful treatment. If you want to work through the trade-offs in detail, here’s a dedicated guide on the debt-versus-invest decision for physicians. For now, the habit-first sequence above gives you a solid footing.
The habit matters more than the return
Medical school debt in Canada is large, but it is not a verdict on your financial future. The trainees who do well tend to be the ones who build steady habits early, not the ones who chase quick wins.
Clear high-interest debt, bring discipline to your line of credit, and start a registered account when you are ready. Do those things consistently, and the habit will carry you further than any single year's return ever could.
