Can you still set up direct deposit after you filed your taxes for the year? I just filed them

Yes, but your refund may still come as a cheque. You will still get future payments deposited directly, so it's a good idea to do it.

This CRA web page lists ways you can set up direct deposit: https://www.canada.ca/en/revenue-agency/services/about-canada-revenue-agency-cra/direct-deposit.html
