Do not want to hurt you. Here in Canada, no one cares or ask about 20 hours work rule. You are just FREE to work as long as you want. You really need SIN number to work. Its very rare to find a REGULAR cash base job. You can find a lot of irregular (just for 3 or 4 days) cash based jobs.
What you are saying is completely out of the topic
I do have a SIN number of course
I have never talked about illegal options to work in Canada
It is really hard to try to understand what you are trying to say
