Ontario's small business rate drops to 2.2% effective July 1, 2026 (from 3.2%). Corporations with a fiscal year straddling that date get a blended rate. Rent-to-own arrangements only produce a CCA claim once you own the asset. A straight lease is a current expense with no write-off of the purchase price.
