Generally speaking it's extremely difficult to get a work permit. The first step is to find an employer who is willing to offer you a full time job. As a next steps, that employer must obtain an approved LMIA. This process requires the employer to advertise the job for at least a month first to prove that no Canadian could be found for the role. Next the employer must pay a $1,000 fee and then typically wait for 2-4 months for the LMIA application to be processed with no guarantee of approval. If the LMIA is approved, you can then apply for a work permit tied to that specific employer.
