I have incorporated many companies in Canada and have always marveled at the lack of vetting. You’d think they would want to see some identification on the incorporation docs. But no. You just fill in a web form and pay $20 or whatever.

You can incorporate federally and leave it at that. Extra-provincial registration is required if you carry on business within a specific province.
Provincial/territorial corps are all around $300+, but don't have the $20/year filing fee.
