I am currently living in Montreal but I was living in Vancouver from November 2022 - February 2024. For my contact information, should I keep an address in Vancouver?

My lease in Montreal is up at the end of June. Should I use an address of a family member or friend in Vancouver or just keep it on this lease address for now?

Troubleshooting

You should use an address that you can receive mail at. Whichever address you use, please make sure that the CRA also has this address before you NETFILE your return.
