Nurse
Salary: $72,000 on average
Especially in Ontario, British Columbia and Alberta there is a high demand for registered nurses. You'll need a nursing qualification, preferably a degree, as well as licensing with the Canadian Nurses Association and (for some jobs) with the relevant provincial regulatory body. According to Workopolis, nursing is the top job where you can get hired straight out of university.
