Canada separation: how is child support worked out?

Canada’s Federal Child Support Guidelines use tables based mainly on the paying parent’s income, the number of children and the applicable province or territory, with additional amounts possible for certain special or extraordinary expenses. Provincial or territorial rules can also matter depending on the family-law route. Official source: Department of Justice Canada Federal Child Support Guidelines.
