Hi i applied student visa to canada on april 1st 2021 stating single and i got married on april22nd (urgent marriage)and got my study permit and landed in canada can i inform ircc now abt my marriage and call my wife on spouse work permit
your study permit was already issued with you as single -- you can only ammend the study permit if there was a mistake from IRCC. In your case, you should have raised a webform to alert IRCC about the status change and if they did not respond, you should have told the border agent (with proof of your webforms).
As of right now, if you try to get your spouse a work permit, its gonna look like you hid the relationship and it may not go down well for either of you. I suggest professional help --this is above almost anyone on this forum.
