How accurate are they?

Our landlord & tenant calculators use up-to-date statutory rates, provincial and state data, and the same formulas lawyers and courts rely on. They are designed for planning and research — actual outcomes depend on your specific facts, jurisdiction, and judicial or agency discretion. Rates are reviewed and updated as laws change. For decisions that matter, confirm the numbers with a licensed lawyer.

Canada and United States coverage

Legal rules differ sharply between the two countries, so every landlord & tenant calculator is built in a Canadian version (using provincial rules) and a US version (using state-level rules). You are viewing the Canada edition; switch countries any time from the calculator hub.

Free to embed

Law firms and legal sites can embed any of these landlord & tenant calculators free — each has a one-click embed that drops an interactive widget onto your own site, with a "Powered by Lexscale.ai" link and no API key required.
