Where to mail t4 ontario

In Ontario, Canada, the T4 slip is typically mailed to employees by their employer by the end of February each year. If you're looking to mail a T4 slip to the Canada Revenue Agency (CRA), you can send it to the following address:

Canada Revenue Agency T4 Processing 1400-555 René-Lévesque Blvd. West Montréal, QC H2Z 1X4

However, it's important to note that the CRA recommends filing your T4 slip electronically through the CRA's My Business Account or the Represent a Client service. This is a more secure and efficient way to submit your T4 slip, and it can help reduce the risk of errors and delays.

If you're unable to file electronically, you can mail your T4 slip to the address above. Make sure to use the correct postage and ensure that your slip is properly completed and signed.

It's also important to keep a copy of your T4 slip for your records, as you may need to provide it to the CRA or your employer in the future.
