Thank you PMM, But would not it have negative impact on my application, because I am not suppose to work more than 20 hours per week on study visa, and if not will my experience count. Please advise
Your U.K. study visa and U.K. study permit is governed by U.K. law, and NOT Canada's law.
The fact that you worked for more hours than you were legally allowed to under U.K. laws has nothing to do with Canada's laws and thus, it will not have a negative impact on your Canada immigration application.
All Canada wants to see is your work experience and proof of it with reference letters from your employers.
