How Do I Find My Tax Number in Ontario?
Quote from viponen on March 28, 2026, 5:31 pmHi everyone,
I’m trying to understand how the tax number Ontario system works and how individuals or small businesses can obtain or verify their tax number in Ontario, Canada. I recently moved here and I’m a bit confused about whether the tax number is the same as a business number or a separate identifier for filing taxes.
Can anyone explain the process for registering, where to apply, and what documents are needed? Also, how long does it usually take to receive it after application? Any personal experiences or step-by-step guidance would be really helpful for a beginner like me.
