Child support is a minor child's entitlement to financial support from both separated parents for their day-to-day expenses. A parent's child support obligation is based on his/her gross annual income, and the amount payable can be found in the applicable province table within the Federal Child Support Guidelines (see the "Resources" section for a link to a Child Support Calculator). There may be circumstances in which the strict child support amount will not apply.
Extraordinary expenses refer to the child's expenses which are outside of everyday expenses and therefore are payable on top of regular child support. These expenses may include: daycare, music lessons, soccer team fees, hockey tournaments, and university/college tuition.
Spousal support refers to a person's potential entitlement to support from the other, and the obligation and amount payable are driven by case-specific factors, such as (but not limited to): Both people's age, duration of marriage, age(s) of child(ren) if any, both people's economic circumstances, employment, etc.
One thing to note is the existence of the Family Responsibility Office, which can be involved (voluntarily or court ordered) in the collection and payment of both child and spousal support.
