Apply for jobs on Canadian job sites like Indeed. You need a job offer and your employer needs to file for and pay $1k for a LMIA. The LMIA shows that no Canadian or PR could be hired, only you. Then with LMIA, you apply for a closed work permit. For the permit, you show that you are experienced to do the job. Depending on the job requirements, you may need IELTS for language and ECA for education. You may need to be licensed too so look at provincial requirements.
