There are the usual ways of looking for work, like LinkedIn and other job platforms, but in Canada there's also what's known as the Job Bank which is a government of Canada website where employers may or may not advertise positions that they want to fill. Generally speaking, employers that are looking to hire foreign workers are required to advertise on the Job Bank. So that's one place for prospective applicants to look for jobs. There are also provincial government job websites where jobs that are available in a certain province, for example, in Quebec, can look for jobs.
