In many cases, the Child Support Guidelines can assist parties in determining the appropriate amount of child support payable. The child support table look-up (link to www.justice.gc.ca/eng/fl-df/child-enfant/look-rech.asp ) will help you find the base amount of child support payable. However, there are situations where this may not be the final payable support amount. Often, there are special and extraordinary expenses to be shared, such as child care expenses. Shared custody can also result in a varied child support amount. The table amount of child support payable may be adjusted to reflect the amount of time that each parent cares for the children.
