Update your CRA information

Change your marital status

You must tell the Canada Revenue Agency (CRA) about your new marital status by the end of the following month after your status changed. For example, if your status changed in March, you must tell us by the end of April. 

Notify the CRA if:

If you have separated, wait until 90 consecutive days have passed before telling us.

We will recalculate your benefits based on your new marital status and adjusted family net income. The adjustment will start the month after your marital status changed.
