There is no legally set of hours that dictates full time or part time hours.
Neither the Canadian Employment Code or the Alberta employment code.
However, there is a generally accepted cut off point that most employers adhere to?
How many hours are considered full time in Alberta?
In Alberta, and most of Canada, Full Time employment is defined as 30 or more hours worked in a week.
Part time employment is defined as less than 30 hours per week.
This is not legally set it stone. Individual employers can layout their employment agreements to determine where the cut off point is. Most employers follow the 30 hour rule in Canada.
