In the case of a divorce, alimony and child support are governed by the federal legislation. I know that, in Quebec, a special system is in line with the federal legislation when it comes to divorce. Consequently, for both married and unmarried couples, the scale for setting alimony and child support could be similar. Of course, if the bill is passed, that would be evenly shared. I assume that the alimony and child support amounts paid by both types of couples would be affected, since those amounts are also based on the parents' custody time.
