A borrowing limit, not an income
A line of credit lets you borrow, repay and borrow again within an approved limit. Interest applies to the amount used, not the unused room. A $400,000 approval does not put $400,000 in your account or mean that amount fits your future budget. Some lenders release access in stages as you progress through school.
The useful question is how much you need this year after other funding, plus enough room for later tuition, interest and unexpected costs. A student with dependants, prior debt or a longer training path may need a very different plan from a classmate. Start with an annual spending plan before choosing a limit.
Compare what the banks offer
Selected public medical-student offers checked in 2026 are below. These are examples to compare, not a ranking or a promise of approval. Read the actual agreement, including annual access limits and conditions for keeping the preferred rate.
| Lender | Public offer | What to confirm |
|---|---|---|
| Scotiabank | Up to $400,000 at its prime rate minus 0.25 percentage points. | No required payments through the advertised school/residency period and 24 months afterward while within the credit limit. Interest still accrues. |
| CIBC | $400,000 medicine guideline at its prime rate minus 0.25 percentage points. | Interest payments are required. The page's headline and footnote describe the grace-period end differently; get your exact residency and repayment dates in writing. |
| RBC | Up to $400,000 for eligible students; up to $425,000 for residents. Preferred pricing requires Healthcare Advantage eligibility. | Annual access and minimum payments; continued revolving access differs for Canadian and foreign-school graduates. |
Also compare account fees, card rebates and what ends when your status changes. Optional creditor insurance is a separate decision. FCAC explains that loan insurance is not required for student-line approval. Ask for its price, exclusions and overlap with any coverage you already have.
How interest reaches your balance
Your rate usually combines the lender's prime rate and an agreed adjustment. The lender sets its prime rate; a Bank of Canada announcement does not itself rewrite your contract. A variable rate can change while you carry the debt. The site's 2026 calculator assumptions use prime of % and a line rate of %. These are not a live rate feed. Use your statement's rate for your own estimate.
Interest starts when you draw money. If your agreement permits unpaid interest to be added to the line, future interest applies to that larger balance. Other agreements require a monthly interest payment. Borrowing again to make that payment still increases your total debt; paying interest from earnings or savings is what stops interest alone from growing the balance.
Illustration: at a constant 5%, a $100,000 balance costs about $5,000 a year before compounding, balance changes and the lender's day-count method. A one-percentage-point increase adds about $1,000 a year on that balance. This makes a higher-rate scenario useful even if today's payment is comfortable.
The site's model illustrates borrowing $40,000 a year for four years at %: about at graduation, including of interest, and about after two further years with no payments. It assumes a borrowing schedule and constant rate, not your lender's exact statement calculation. Change the amounts and rate in the line of credit calculator.
Which funding to use first
- Check non-repayable funding. Apply for eligible grants, bursaries and scholarships. Read conditions such as academic progress, reporting duties or a service commitment.
- Compare government aid. New interest has not accrued on Canada Student Loans since April 2023. Provincial terms differ, and older federal interest can still be owing. Government debt may also offer assistance that a bank line does not.
- Borrow the remaining gap. Draw near the date an expense is due, while allowing time for transfers. Keep enough accessible cash for scheduled payments.
NSLSC confirms the federal interest change. Before refinancing government debt, compare the benefits you would surrender in the government-loan guide. A lower-looking payment is not proof of a better deal.
Plan for the next stage before it arrives
Do not assume your line of credit keeps its school terms automatically through residency, fellowship, parental leave or a training interruption. Send any required proof of enrolment or employment and ask for the next review date. A repayment grace period can mean no principal payments while interest remains payable or continues accumulating.
Before residency ends, request a written payment schedule showing the balance, rate, required payment and whether the line stays revolving or becomes a loan. Test that payment against expected take-home income and practice costs. A new staff income is not all available for debt: tax, licensing, insurance and delayed billings may also need cash.
Co-signers and credit are separate from the limit
A co-signer can become responsible if you cannot repay. Before involving someone, discuss the full exposure and get any release conditions in writing. Your income prospects do not remove their risk. FCAC's student-line overview explains this responsibility.
Keep every required payment current, including a bundled credit card. When planning a mortgage, disclose the line and ask how the lender will count it in qualification. A large approved limit and a strong score are not the same as affordable housing. See credit basics for the practical checks.
Six habits that make the balance easier to manage
- Set an annual borrowing target that includes interest.
- Transfer living money monthly; handle tuition and other large bills separately.
- Check balance, available room and posted interest each month.
- Compare actual borrowing with the plan before the next semester begins.
- Keep money needed for tuition or emergencies out of volatile investments.
- If you can pay interest from residency income, check that the balance actually stops rising.
Take these questions to the bank
- How much can I access now, and what unlocks the next year's amount?
- What payments are required at each stage, and can interest use up my available limit?
- Which rate, fees and account conditions apply after graduation and residency?
- What changes if I take leave, extend training, move abroad or leave medicine?
- What is the repayment or conversion date in my agreement, and can you show the projected payment?
- What conditions apply to a co-signer's release?
