Question & AnswerHow can child support be changed?
Use the Child Support Service
In some cases, you may be able to use the online Child Support Service (CSS) to change where there has been a change to the parent’s income.
The government calculates the amount of child support to be paid using the new income information. They then mail you and your partner a that tells you how much child support must be paid.
But sometimes you cannot use the CSS to change child support. For example, if any of these are true:
- you used CSS to decide or change the child support amount less than 6 months ago
- you or your partner live outside of Ontario
- the payor parent earns more than 20% of their income from self-employment, rental income, or investment income
- you have or
Shared used to be called or . Split parenting time used to be called .
That payor parent can disagree if the information the other parent gave was wrong. If they do not respond within 25 days of the notice being sent, the CSS might change their support payment without their response. So it is important to respond to a notice from the Ministry of the Attorney General if you don’t agree with the change.
You can talk to a lawyer about whether you should use the CSS.
