Track rent due, rent received and arrears
Record each tenancy’s monthly rent, due date, deposits held and every payment received. Comparing rent due with rent received each month shows arrears before they become a pattern. Note the lease start, renewal and any notice dates alongside the amounts.
Tenancy rules, notice periods, deposits and rent-increase limits are provincial. Use your province’s residential tenancy authority rather than a national summary; the links below cover Ontario, British Columbia and Alberta.
Log recurring costs as they happen
Property tax, landlord insurance, condo or strata fees, management fees, owner-paid utilities and routine maintenance make up most operating costs. Record the date, supplier, amount and property for each one, and attach the receipt or invoice the same day rather than reconstructing it at year end.
Separate repairs from capital improvements
Repairing a broken element to its original condition is generally treated differently from an improvement that extends the property’s life or upgrades it. CRA explains this distinction between current and capital expenses; capital work may be claimed through capital cost allowance rather than deducted in the year. Label each larger job when it happens and keep the quote, invoice and photos.
Split mortgage interest from principal
A mortgage payment combines interest and principal. Principal repayment reduces your debt and is not a rental expense; interest on money borrowed to earn rental income may be deductible. Download the annual lender statement and record term end, rate and balance, so a renewal never surprises your cash-flow budget.
Run a short monthly review
Each month, compare income and costs with your budget, note any arrears, check upcoming lease and mortgage dates and confirm the reserve balance. Ten minutes a month catches a rising strata fee or a slow-paying tenant far earlier than an annual review.
Keep personal and rental money apart where possible. If a property has personal use, or you rent part of your home, record how costs are shared so the split can be explained later.
Hand over accountant-ready records
At year end, provide total rent by property, categorized expenses with receipts, the mortgage interest statement, a list of capital work and any purchase or sale documents. This guide explains record-keeping, not tax treatment: confirm what is deductible with a Canadian tax professional.
