This page lists the Canada Revenue Agency’s phone numbers and hours, the tax-centre addresses for mailed returns and correspondence, and the lines for reporting scams. It is part of the Dealing with the CRA directory.
The hours are the same all year. The one change is in peak filing weeks, when the CRA adds extended Saturday hours; the dates and times are posted on its website.
Statutory Holidays
CRA phone lines are closed on federal statutory holidays.

Use the Call-Back Service
When available, the CRA offers an automated call-back option:
Wait for the prompt
Enter your phone number
Hang up and wait
CRA calls you back when an agent is free
This is often faster than holding.
CRA My Account instead of calling
Many tasks don’t need a call at all: CRA My Account shows your returns and Notices of Assessment, slips, registered account room and benefit payments, and lets you update your address and direct deposit. What each part of the account does is covered in the CRA My Account guide, and registering, the Sign-In Partner and CRA user ID options, and getting back in when locked out are on the My Account registration and sign-in guide.
