Child support in Ontario is always calculated using the Federal Child Support Guidelines. If you have found yourself separating from your spouse and have a child or multiple children, then there will be obligations to support the children by means of child support and/or contribution toward special and extraordinary expenses.


Whether you are separated from your spouse or not, both parents possess a responsibility to financially support their offspring. Generally, and simply speaking, child support is primarily calculated based on income of the parent(s) and the number of children involved. There are many online child support calculators to give you an estimate or idea of what your child support will be based on your income level. Of course, there are special circumstances that can be taken into account when calculating child support that are not available to individuals using the online support calculator. Typically, there is a set list of shared responsibilities and factors to cover in a basic monthly amount of child support, which may include; payments for rent or mortgage to secure the child’s housing, grocery bills, clothing expenses, toiletry expenses, school expenses, and other physical and hygiene expenses. In many cases, parents will also be required to pay for special and extraordinary expenses, such as extracurricular activities, which contribute to the best interest of the child. In these cases, the extra expenses may be necessary and reasonable, reflecting the parents spending habits prior to separating.


In Canada, there is a separate table for each province and territory; therefore, the payor parent must ensure they are referring to the appropriate guidelines, based on where they reside. It is also important to note that the Ontario Child Support Table Guidelines are used if the child or children live in Ontario, but the payor parent lives outside of Canada.

The calculation of child support begins at discussions on where the children will be residing. The relevancy of the children’s residence will determine whose income will be used to determine how much child support is to be paid. Online child support calculators are available on some websites, which can be used as a child support estimator; however, they are not always the most accurate resource to utilize. When there is a shared custody arrangement, where the children are residing at least 40% of the time with both parents, both parents’ income are considered. When there is a primary residency arrangement, where the children are residing with a parent for more than 60% of the time, it’s the income of the non-residency parent that is inputted. It is the gross annual income before taxes and some deductions, which is used to calculate how much child support is.
A child support calculator can calculate how much child support will be paid; however, there are also table amount spreadsheets built within the Guidelines as well. Using software called DivorceMate, which directly takes the information from the Federal Child Support Guidelines, your mediator will be able to determine how much child support payments will be. This software is the most accurate child support calculator that is available in modern years.
In order to estimate what your child support may be, you can use online tools such as a child support estimator, calculator or go directly to the Federal Child Support Guidelines. There isn’t necessarily an average child support payment amount.

There are some very common misconceptions and questions involved with child support when living in Ontario, so here are a few important pieces information to consider. A payor parent may be confused about their obligations and boundaries, when conflicts or disagreements arise with child support. It is important to note that if a parent has limited or restricted visitation with a payor parent, then they are still required to maintain regular child support payments. Child support payments and legal visitation rights are completely different legal matters when co-parenting. Regardless of the access you are provided to your child or children, you must still faithfully provide financial support. To add, child support is not tax deductible; therefore, a payor parent may not claim these payments. It is also important to note that child support looks different in every province within Canada. It is crucial to do your own research and ensure you are fulfilling the support guidelines of the province that you reside. Importantly, both parents must provide financial support to their child or children, regardless of if they were married in the past or not. Therefore, it does not matter if parents were legally married when birthing a child or children, child support is still an obligation. In addition to this, if a payor parent declares bankruptcy at any point, they may still be obligated to provide child support payments to the other parent.
Child support payments must be paid religiously to ensure the success and wellbeing of the child or children, regardless of any personal financial struggles. Although in this instant, child support amounts would be altered in the upcoming years to better suit the financial stability to the payor parent. In many Separation Agreements it is indicated that child support payments be recalculated each year to better reflect the annual income of the payor parent. Therefore, the amount being paid can increase or decrease based on the gross annual income of that specific year. To add, in drastic circumstances any parent may request to the courts that child support payments be increased, decreased, or even eliminated.
