You need a different plan. When you study language in Canada, you almost always aren't legally allowed to work. All you are allowed to do is study.
If you want to be able to work in Canada while you study, then you need to take a real program - like a full time college diploma or university degree. And you'll need to obtain a study permit. To be approved for the study permit, you will need to show that you have enough money to pay for your tuition plus travel/living expenses. This mean you will have to show that you have a balance of at least $20K to pay for your education in Canada. You will also have to make sure that whatever program you take in Canada makes sense based on your previous work experience and education.
