The rate caps at a glance
The Canada Small Business Financing Act sets maximum interest rates that participating lenders may charge borrowers under the program. These are ceilings, not floors — a lender can charge less, but not more.
- Variable-rate term loan:Prime Rate + maximum 3% per year. Most lenders price at or near the cap. At a 4.95% prime (as of early 2026), the all-in rate would be 7.95%.
- Fixed-rate term loan:The lender’s residential mortgage rate for the equivalent term + maximum 3% per year. Borrowers who want payment certainty can lock in at conversion (once, at any point during the loan term). The fixed rate is set on the date of conversion.
- Working-capital line of credit (up to $150,000): Prime Rate + maximum 5% per year. The higher cap reflects the revolver structure — there’s no fixed amortization schedule and the line can be re-drawn after repayment.
The 1.25% annual administration fee is already inside the cap
CSBFP has two ongoing costs beyond the initial registration fee: the interest rate the borrower pays, and an annual administration fee the lender pays to Innovation, Science and Economic Development Canada (ISED). These interact in a way most borrowers never see.
The lender pays an administration fee of 1.25% of the outstanding loan balance each year to ISED. That fee is paid by the lender — not billed separately to the borrower. But the rate cap is set high enough to let the lender absorb the fee and still earn a margin. The practical effect: a lender charging Prime + 3% on a term loan is keeping approximately Prime + 1.75% for itself and remitting 1.25% to the government each year.
The borrower sees the cap as the all-in rate. The split between lender margin and ISED fee is invisible in the loan statement.
How CSBFP rates compare to conventional bank financing
A well-qualified conventional borrower — established business, clean financials, coverage above 1.25x DSCR — typically negotiates a conventional term loan at Prime + 1.5% to Prime + 2.5%, depending on the relationship and the asset class. CSBFP at Prime + 3% is therefore 50 – 150 basis points more expensive on the interest rate line.
The cost differential is the price of the government guarantee. CSBFP makes approvals available to borrowers who cannot get through a conventional credit committee — startups, thin operating history, leasehold-improvement financed projects — and at a 50 bps premium over the best conventional rate, it is among the cheapest risk-priced capital those businesses will find.
For a business that could qualify conventionally, the CSBFP rate premium is real, and the right conversation with a CPA is whether the government-guarantee benefits (lower equity requirement, statutory 25% personal-guarantee cap, access to a broader range of lenders) justify it.
The all-in cost: interest + registration fee + administration fee
The full cost of a CSBFP term loan has three components that need to be modelled together:
- Interest rate:Prime + up to 3% per year on the outstanding balance. This is the largest ongoing cost.
- Registration fee: 2% of the loan amount, one time, at closing. Usually financed into the loan itself (adding to the balance) rather than paid in cash at closing. On a $500,000 loan the fee is $10,000; on a $1,000,000 loan it is $20,000.
- Annual administration fee: 1.25% per year, bundled into the rate cap. Not separately itemized; already reflected in the interest rate the lender charges.
An illustrative example: a $500,000 CSBFP variable-rate term loan over 7 years, with Prime at 4.95%, would carry an interest rate of 7.95%, a one-time registration fee of $10,000 (typically financed), and an effective 1.25% annual administration fee already baked into the 7.95%. Total interest cost over the term, assuming a flat prime and monthly payments, would be approximately $135,000 on a fully-amortizing schedule. Add the registration fee and the actual total financing cost is roughly $145,000 on a $500,000 project.
The same borrower on a conventional Prime + 2% rate (7.95% vs. 6.95%) would save approximately $28,000 in interest over the same term — about 5.6% of the principal. Whether that saving justifies the tighter approval conditions and larger equity requirement of a conventional file is a CPA-modelled trade-off, not an obvious answer.
Rate stability and the variable-to-fixed conversion
CSBFP term loans start as variable-rate by default. Borrowers have one option, exercisable at any time during the loan term, to convert the outstanding balance to a fixed rate. The fixed rate on the conversion date is the lender’s residential mortgage rate for the remaining term + 3%. Once converted, the rate is fixed for the remaining amortization — there is no second conversion back to variable.
The conversion option is most valuable when prime is rising and the borrower has an existing variable-rate CSBFP loan. Locking in when prime is low reduces the risk of payment shock as prime rises. The one-conversion-only rule means timing matters: convert too early (when prime is still low) and the fixed rate is cheap; convert too late (after several prime increases) and the fixed rate is set on a higher base.
This is a cash-flow modelling conversation, not just a rate conversation — the CPA’s projection model needs to show debt service under both scenarios before the conversion option is exercised.
What the rates do not cover
The CSBFP rate caps are regulatory maximums on the loan itself. They are separate from:
- Capital Toolkit’s own professional service fees (disclosed before engagement, not bundled into the loan).
- Legal fees for loan closing (the borrower’s solicitor and, sometimes, the lender’s solicitor).
- Appraisal, environmental assessment, or survey fees required by the lender for real-property loans.
- Any early-repayment or break-cost penalties, which vary by lender (CSBFP does not cap prepayment penalties; they are commercially negotiated).
