The respondent mother brought a motion to change parenting and child support terms established in prior orders.
The parties had a joint custody arrangement with the child's primary residence with the father, and the mother was ordered to pay $211 per month in child support.
After the mother returned to Ontario in 2009, the parties agreed to an equal time-sharing arrangement in March 2010.
The mother sought retroactive support from the father, claiming he earned significantly more income than disclosed.
The father opposed retroactive support and proposed only ongoing support of $500 per month.
The court found the father had improperly diverted income through his corporation and unreasonably deducted expenses.
The court imputed income to both parties and ordered the father to pay $1,050 per month ongoing support and $20,000 in retroactive support, with the mother's arrears rescinded.
