Commercial Mortgage Refinance in Canada

Most commercial borrowers should begin the refinancing process six to twelve months before their mortgage matures. This timeline allows enough runway to assess the existing loan structure, obtain an updated appraisal, compare lenders, negotiate terms, and complete due diligence without the pressure of an imminent maturity date driving the decision.

Starting early matters for several practical reasons. Commercial mortgage approvals take longer than residential transactions. Appraisals, environmental assessments, building condition reports, and lender underwriting all take time, and unexpected conditions or documentation requests can extend the timeline further. Borrowers who begin with six months or more in hand can absorb these delays without losing negotiating leverage or being forced into a renewal on the existing lender’s terms simply because there is no time left to consider alternatives.

Rate lock timing is another consideration. Many lenders will allow borrowers to lock a rate within a defined window ahead of closing. Starting the process early gives borrowers more flexibility to choose when to lock, rather than accepting whatever rate is available in the final weeks before maturity.

The risk of waiting too long is real. A commercial mortgage that lapses past its maturity date typically converts to an open loan at a higher rate, which increases carrying costs while the refinancing process plays out. In some cases, lenders may also apply additional conditions or fees to loans that have passed their scheduled maturity.

For properties that require repositioning, lease-up, or capital improvements before they will qualify for conventional refinancing, the preparation timeline should be even longer. In those situations, planning the refinancing path twelve to twenty-four months out gives the asset time to reach the income and occupancy profile that institutional lenders require.

Commercial lenders in Canada assess refinancing applications primarily on the performance of the property rather than the borrower’s personal income. The key underwriting factors are the property’s net operating income, its current appraised value, the stability and profile of the tenancy, and the borrower’s net worth, liquidity, and relevant experience managing similar assets. Lenders calculate the debt service coverage ratio to confirm the property generates enough income to carry the proposed debt, and they apply a loan-to-value limit to determine the maximum loan amount relative to the appraised value. Environmental status, building condition, and lease expiry profiles are also reviewed, as these affect the lender’s assessment of income sustainability and asset risk over the loan term.

Debt service coverage ratio, commonly referred to as DSCR, is calculated by dividing the property’s net operating income by its total annual debt service obligations under the proposed financing. Net operating income is the income remaining after operating expenses are deducted from gross revenue, before mortgage payments. A DSCR of 1.0 means the property generates exactly enough income to cover its debt payments. Most Canadian commercial lenders require a minimum DSCR of 1.20 to 1.35 on a stabilized basis, meaning the property must produce at least 20 to 35 percent more income than is needed to service the debt. Lenders also stress test the DSCR at a rate slightly above the contract rate to confirm the property can carry the debt if conditions deteriorate.

Loan-to-value, or LTV, is the ratio of the proposed loan amount to the property’s current appraised value. If a property appraises at $5 million and the lender will advance up to 65 percent LTV, the maximum loan is $3.25 million. On a commercial mortgage refinance in Canada, conventional lenders typically cap LTV at 65 to 75 percent depending on the asset class, market, and borrower profile. The LTV ceiling directly determines how much equity can be accessed through a refinance and how much capital the borrower must leave in the property. Higher LTV means more proceeds but also more debt service and a narrower margin of safety if the property’s income or value declines. Borrowers seeking maximum proceeds should understand that higher leverage typically comes with higher rates and more restrictive covenant terms.

A straightforward commercial mortgage refinance with an institutional lender in Canada typically takes 45 to 90 days from initial engagement to funding. This timeline covers property valuation, lender underwriting, condition satisfaction, and legal closing. Transactions involving CMHC-insured financing, complex ownership structures, environmental concerns, or multiple lender consent requirements can take longer, sometimes four to six months. Alternative and private lender refinances can move faster, often closing in two to four weeks, because their underwriting process is less documentation-intensive. The most reliable way to manage the timeline is to begin the process well in advance of maturity and engage a commercial mortgage broker who can coordinate all parties and keep the file moving efficiently.

The documentation package for a commercial mortgage refinance in Canada typically includes a current appraisal of the subject property, trailing twelve-month operating statements, a current rent roll, copies of existing leases, a Phase I environmental site assessment, a building condition report, and the borrower’s financial statements and personal or corporate tax filings for the most recent two to three years. Lenders may also require a copy of the existing mortgage terms to confirm the maturity date, prepayment provisions, and any inter-creditor arrangements in place. For CMHC-insured refinances, additional program-specific documentation is required. Requirements vary by lender and deal complexity, and a commercial mortgage broker will confirm exactly what each lender needs before the file is submitted.

An interest rate differential, or IRD, penalty is a prepayment charge that applies when a borrower breaks a fixed-rate commercial mortgage before the end of its term. The penalty is calculated as the difference between the original contract rate and the current rate the lender can obtain for the remaining term, multiplied by the outstanding loan balance and the time remaining. If rates have fallen since the loan was arranged, the IRD can be substantial because the lender is compensating for the lost interest income over the remaining term. Commercial IRD calculations vary by lender and can be significantly larger than residential prepayment penalties. Before breaking a commercial mortgage early to refinance, borrowers should obtain a precise prepayment quote from the existing lender and model whether the savings on the new rate over the remaining term outweigh the cost of exiting early.

Most commercial borrowers should begin the refinancing process six to twelve months before their mortgage matures. This timeline provides sufficient runway to obtain an updated appraisal, compare lenders, complete due diligence, and close without the pressure of an imminent maturity date forcing a rushed decision. Starting early also preserves rate lock flexibility and gives borrowers time to absorb unexpected delays from third-party reports or lender conditions. For properties that require lease-up, capital improvements, or repositioning before they will qualify for conventional refinancing, planning should begin twelve to twenty-four months out to allow the asset time to reach the income and occupancy profile that institutional underwriting requires. Commercial mortgages that lapse past maturity typically convert to open loans at higher rates, making early engagement the most reliable way to protect the borrower’s financing position.

A fixed rate locks the interest rate for the full term of the loan, providing payment certainty regardless of how market rates move during that period. A variable rate is tied to the lender’s prime rate and fluctuates with changes in the Bank of Canada’s overnight rate, meaning payments can increase or decrease over the term depending on rate movements. Fixed rates are generally higher than variable rates at the time of commitment because the borrower is paying a premium for certainty. Variable rates carry more short-term risk but can produce lower total interest costs over the term if rates remain stable or decline. The right choice depends on the borrower’s risk tolerance, cash flow requirements, investment horizon, and view on the rate environment. A commercial mortgage broker can model both scenarios against the borrower’s specific property and financing structure to support an informed decision.

A property with significant vacancies or deferred maintenance will face challenges qualifying for conventional commercial mortgage refinancing in Canada, as institutional lenders base their underwriting on stabilized net operating income and expect the property to be in a condition consistent with its market value. However, alternative lenders and private commercial mortgage lenders can often accommodate these situations, particularly where the borrower has a credible plan to address the issues and the underlying asset value supports the loan amount at an acceptable loan-to-value ratio. In some cases, a bridge loan or private mortgage is the appropriate interim solution, providing capital to fund capital improvements or lease-up while the property moves toward a stabilized profile that qualifies for conventional refinancing. A commercial mortgage broker can assess where the property currently sits relative to lender thresholds and identify the most practical path to long-term financing.

Conventional commercial mortgage refinances in Canada are typically available with amortization periods of 20 to 30 years, depending on the lender, asset class, and borrower profile. Longer amortization reduces monthly debt service but increases total interest paid over the life of the loan. Shorter amortization builds equity faster but requires higher monthly payments. CMHC-insured multi-family refinances can qualify for amortization periods of up to 40 years under certain programs, which produces meaningfully lower debt service and improves cash flow on qualifying rental properties. The amortization period is an important structuring decision that should be considered alongside the term length, rate type, and the borrower’s investment horizon. Extending amortization at refinancing is one of the most effective ways to improve cash flow on a commercial property without reducing the loan amount.

A commercial mortgage refinance can improve, maintain, or reduce cash flow depending on how the new loan is structured relative to the existing one. Securing a lower interest rate on the same loan balance reduces monthly interest expense directly, which flows through to improved cash flow. Extending the amortization period lowers the principal and interest payment even if the rate remains similar. Accessing equity through a cash-out refinance increases the loan balance and therefore the debt service, which reduces cash flow unless the proceeds are deployed into income-generating improvements. Borrowers should model the impact of the proposed refinance on their net operating income, debt service, and cash-on-cash return before committing to a structure. A commercial mortgage broker can provide this analysis as part of the refinancing assessment to ensure the new structure serves the borrower’s income and investment objectives.

MLI Select is a CMHC multi-unit mortgage loan insurance program designed to incentivize the development and preservation of affordable, energy-efficient, and accessible rental housing in Canada. It replaced the previous MLI program and offers tiered benefits to borrowers whose properties meet defined criteria across three streams: affordability, accessibility, and energy efficiency. Properties that score sufficient points across these streams qualify for enhanced loan terms, including higher loan-to-value ratios, longer amortization periods, and lower insurance premiums than standard CMHC insured financing, which translates into lower interest rates and improved debt service on qualifying refinances. MLI Select applies to refinancing of existing multi-family rental properties with five or more units, making it a significant opportunity for owners of qualifying residential rental assets to access insured refinancing at terms that are not available through conventional channels. Eligibility assessment and file preparation for MLI Select requires familiarity with the program criteria, and working with a commercial mortgage broker who understands the program from the outset ensures the application is structured correctly.
