To my knowledge, if someone employs you without checking a valid permit is also illegal and you should not claim it if you dont want to show that you did something without permits.
I have same issue i worked full time got paid but without permit, and of coz i can not show it now since if i do show it, it means i did something INVALID / ILLEGAL without permit and my employers never checked it.
Hi, just be cautious in this respect. If you were issued a T4 when you worked for this organization you must report it in your Tax Return. During the processing of your application, CIC reserves the right to talk to other government departments about your activities in Canada.
To check your Canadian work history they may verify what you have reported in your EE profile to the T4 information reported in your Canadian tax return. Not saying they will bit be prepared to answer questions just in case.
