How is child support calculated in Ontario after separation?
For many parents, child support is one of the first financial questions that arises after a separation or divorce.
In Ontario, child support is generally calculated under the Child Support Guidelines, based on factors including income, the number of children and the applicable support tables. Parenting arrangements, special or extraordinary expenses, and other circumstances may also affect the amount payable.
At MFC Lawyers, our family lawyers help parents in Guelph, Milton and surrounding Ontario communities understand their child support rights and obligations.
We assist with:
• Child support calculations
• Determining income for support
• Shared parenting and child support
• Section 7 expenses
• Financial disclosure
• Retroactive or unpaid support
• Changes to existing support arrangements
Child support isn't just about reaching a number. It's about making sure the calculation is based on the **right income, accurate information and your family's circumstances**.
If you are separating or have questions about an existing child support arrangement, contact MFC Lawyers to speak with an Ontario family lawyer.
