Under Canada Revenue Agency (CRA) guidelines, if parents in Ontario share parenting time equally (roughly a 50/50 split), they must notify the government to have the Canada Child Benefit (CCB) divided. In a true shared parenting arrangement, each parent generally receives exactly 50% of what they would have received if they had the child full-time.
Navigating family law and taxes after a separation in Toronto, Ottawa, or Sudbury can be incredibly confusing. The Canada Child Benefit (CCB) is a tax-free monthly payment made to eligible families to help with the cost of raising children under 18 years of age. Historically, the parent who had “custody” received the entire benefit. However, under modernized divorce laws, courts now focus on “parenting time.” When parents share this time equally, the federal government requires that the financial benefits be shared as well.
Many parents mistakenly believe they can privately agree that one parent keeps 100% of the CCB in exchange for lower child support payments. 📍 This is highly dangerous. The CRA actively audits CCB claims, and if they discover you are claiming 100% of the benefit while your child lives with your ex-partner half the time, you may be forced to repay thousands of dollars in overpayments. Working with a local Ontario family lawyer ensures your separation agreement accurately reflects your parenting time and protects you from federal tax penalties.
Step-by-Step Process for Splitting the CCB in Ontario
Updating your CCB status is a federal process managed by the CRA, but it relies heavily on your provincial Ontario separation agreement or court order. Following these steps ensures both parents receive their legal entitlement without triggering a tax audit.
Step 1: Determine Your Exact Parenting Time Percentage
Before contacting the CRA, you must confirm that you actually have a “shared custody” arrangement for tax purposes. ⌛ The CRA generally defines shared custody as an arrangement where the child lives with each parent roughly equally (between 40% and 60% of the time). If your child only visits you every other weekend (e.g., 20% of the time), you are not eligible to claim the shared CCB. The parent with whom the child resides 80% of the time remains the primary caregiver and receives the full benefit.
Step 2: Finalize a Written Separation Agreement or Court Order
The CRA will eventually ask for proof of your living arrangement. You should have a formalized, written separation agreement or a court order from the Ontario Superior Court of Justice or the Ontario Court of Justice. This legal document must explicitly state the parenting schedule, such as a “week-on, week-off” rotation or a “2-2-3” schedule. The document should clearly show that the child resides with each parent at least 40% of the time.
Step 3: Submit the Shared Custody Notification to the CRA
Once your parenting time is established, you must immediately notify the CRA of the change in your child’s living arrangements. 📝 You can do this quickly through your online “My Account” on the CRA portal by updating your marital status and child information. Alternatively, you can fill out and mail Form RC66 (Canada Child Benefits Application) along with the RC66SCH (Status in Canada and Income Information) directly to your regional tax centre.
Step 4: Await the CRA Reassessment and Payment Adjustment
After receiving your notification, the CRA will recalculate your entitlement. In a 50/50 split, the CRA does not simply split one cheque in half. Instead, they calculate what Parent A would receive based on their individual household income, and give them 50% of that amount. Then, they calculate what Parent B would receive based on their distinct household income, and give them 50% of that amount. Because the CCB is income-tested, the lower-income parent will naturally receive a slightly higher monthly payment than the higher-income parent.
Step 5: Adjust Child Support Calculations Accordingly
Finally, your family lawyer must factor the CCB into your overall child support obligations. 💰 Under Section 9 of the Federal Child Support Guidelines, shared parenting allows for a set-off calculation (subtracting the lower income parent’s table amount from the higher income parent’s amount). The fact that both parents are receiving a portion of the CCB helps offset the daily living expenses for the child across both Ontario households.
How Much Does it Cost in Ontario?
Updating your CCB status with the federal government is free, but establishing the legal documents required to prove your arrangement involves legal fees.
| Service / Expense | Estimated Cost (CAD) | Description |
|---|---|---|
| CRA Notification Form (RC66) | $0 CAD | There is no government fee to update your parenting status with the Canada Revenue Agency. |
| Drafting a Separation Agreement | $2,000 – $5,000+ CAD | Lawyer fees to draft a legally binding parenting plan that outlines your exact 50/50 schedule. |
| Independent Legal Advice (ILA) | $400 – $1,000 CAD | The cost for the second parent to have their own lawyer review the agreement before signing. |
| Repayment Penalty (If Audited) | Varies (Thousands) | If you wrongly claimed 100% of the CCB during a 50/50 split, you must repay the overpaid CAD amounts. |
Investing in a properly drafted separation agreement ensures you do not face costly clawbacks from the CRA years down the road. 🔒
How Long Does the Process Take?
The timeline for resolving CCB claims depends on how quickly you and your ex-partner can agree on a parenting schedule. Drafting and signing a separation agreement with the help of Ontario family lawyers typically takes between 2 to 4 months.
Once you submit your Form RC66 or update your CRA “My Account” online, it generally takes the government about 8 to 11 weeks to process the change. 📅 If the CRA requires further information or decides to audit your claim (requiring letters from schools or doctors confirming the shared arrangement), the delay can extend an additional 2 to 3 months before your payments are correctly adjusted.
Frequently Asked Questions (FAQ)
Can we agree that one parent claims 100% of the CCB?
No. If you actually have a 40-60% shared parenting arrangement, the CRA explicitly states that you cannot choose to allocate 100% of the CCB to one parent, even if it is written in a legal separation agreement. The CRA strictly enforces the 50/50 benefit split based on the reality of the child’s living situation.
What happens if my ex refuses to notify the CRA?
If your ex refuses to update their status and continues claiming 100% of the benefit, you can notify the CRA yourself. Submit your shared parenting agreement to the CRA. They will investigate, request proof of the schedule from both parents, and eventually claw back the overpayments from your ex to pay you your rightful share.
Does a 60/40 split count for the shared CCB?
Yes. The CRA considers a child to be in a shared custody arrangement if they live with each parent at least 40% of the time. If the split is 60/40, both parents are required to split the CCB as shared parents.
Does my spousal support affect my CCB?
Yes, indirectly. Spousal support is generally considered taxable income for the recipient and a tax deduction for the payer. Because the CCB is calculated based on your net “Adjusted Family Net Income,” receiving high spousal support may increase your net income, thereby slightly reducing your monthly CCB entitlement.
What proof does the CRA need if they audit my parenting time?
If the CRA audits your shared custody claim, they will ask for letters from objective third parties who know your child’s routine. This includes letters from school principals, daycare providers, family doctors, or religious leaders confirming that both parents actively pick up, drop off, and care for the child.
