How to meet the hours of work requirement
To be eligible for this stream, you must have worked in Canada for at least 12 months full-time, or an equal amount of part-time hours (at least 1,560 hours in total) in the 3 years before you apply.
You must have been allowed to work legally in Canada for these hours to count. This means you either had a valid work permit, or you were exempt from needing a work permit.
