Mail your paper T1 General return to one of three Canada Revenue Agency tax centres — Winnipeg, Sudbury, or Jonquière — based on where you lived on December 31 of the tax year. For non-residents, the address depends on both your country of residence and your last Canadian province.

Payments Go to a Different Address
If you owe tax, do not put the cheque in the same envelope as your return. Payments go to a separate address. Make your cheque or money order payable to the “Receiver General for Canada” and mail it to:3Canada Revenue Agency. Pay Through the Mail – Payments to the CRA

Include a T7DR remittance voucher so the CRA can match your payment to your account. If you do not have a voucher, write your Social Insurance Number on the cheque’s memo line or on a separate sheet inside the envelope.4Canada Revenue Agency. Remittance Vouchers and Payment Forms – Payments to the CRA Mailed payments can take up to 10 business days to post to your account, so send yours well ahead of the deadline to avoid interest.3Canada Revenue Agency.

What to Put in the Envelope
Your envelope should contain the completed T1 General return and any required schedules, such as Schedule 1 for the federal tax calculation. Forms are available on the CRA website, and paper packages can be requested by calling 1-855-330-3305.5Canada Revenue Agency. Get a T1 Income Tax Package
Attach one copy of each information slip you received, including T4 slips for employment income and T5 slips for investment income, along with receipts for any deductions or credits you are claiming. Electronic filers keep receipts at home; paper filers put them in the envelope.6Canada Revenue Agency. What Documents Do You Include With Your Return and What Records You Keep Print your Social Insurance Number and current mailing address clearly on page 1, since CRA staff key that information in by hand.
