To avoid headaches in the future by way of reduced or withheld tax refunds, and extensive paperwork thereafter, you should inform the CRA if the following events happen (among others), with appropriate supporting documentation.
- Date of marital status change, either when you marry or, undergo a separation/divorce.
- Spousal and child support payments, as per court decreed/divorce settlement documents
- Change of address - New child information: as per birth certificate
