Hi there!
I wanna job offer letter from Canada.
Then apply to jobs. No jobs here. A job offer doesn’t let you work in Canada. 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. Most if not all jobs posted will say that you must be a citizen, PR or a person with work authorization to apply so no point in applying for those jobs.
