The first thing we duplicated was the toothbrush. The school bag still travels, along with whichever library book my daughter has decided is indispensable that week. When we settled into alternating weeks, I assumed her mother would receive the Canada Child Benefit and send me half.
That is not how the CRA calculates shared-custody payments. Each eligible parent has a separate entitlement, based on their own family circumstances.
Check the actual care arrangement
For CCB purposes, the CRA generally treats care as shared when a child lives with each parent 40% to 60% of the time, at different addresses, and each is primarily responsible while the child is with them. The ordinary CCB conditions still apply, including the child's age, the applicant's residence and immigration or citizenship requirements. CRA eligibility and custody rules.
A label in a parenting agreement does not replace the facts. If the child lives with one parent more than 60% of the time, that parent generally receives the full amount calculated for them; a parent with less than 40% is generally not eligible for that child. Keep a calendar reflecting the actual arrangement, including changes.
Calculate half of each parent's own entitlement
Each eligible shared-custody parent receives 50% of what they would receive with full custody, using their own adjusted family net income. The CRA does not divide one former household's payment into two equal deposits. It also will not use another percentage or send the whole shared-custody benefit to one parent by agreement. How shared custody changes the calculation.
Suppose the full-custody calculation would produce $500 a month for me and $350 for my daughter's mother. These amounts depend on each parent's income; they are not universal benefit rates.
| Parent | Shared-custody amount |
|---|---|
| Dany | 50% of $500 = $250 |
| Other parent | 50% of $350 = $175 |
The different deposits are consistent with the same custody schedule. For July 2026 through June 2027, the income reference is 2025. A new spouse or common-law partner can affect a parent's family-income calculation; the former couple's old combined income is not permanently attached to the child.
Update custody and marital status separately
Both parents must tell the CRA immediately when shared custody starts. The CRA lists an application through the account or Form RC66; a parent already receiving full benefits has additional update options. Do not leave the old full payment in place and privately redistribute it. Keeping the CCB file current.
The 90-day separation rule concerns marital status. After a relationship breakdown has lasted at least 90 consecutive days, the effective separation date is the first day of that period. It is not permission to leave a changed custody arrangement unreported for three months. Updating marital status.
Keep both tax-return files current, save the custody-update confirmation and read the new benefit notice. The separate eligible-dependant tax credit has different rules; receiving half the CCB does not establish a right to half that credit.
