CPP Pension Splitting in Ontario Divorces (2025 Edition)
When an Ontario marriage or common-law relationship ends, dividing Canada Pension Plan (CPP) credits can transfer tens of thousands dollars in lifetime, inflation-indexed retirement income from one spouse to the other. CPP credit splitting—legally called the Division of Unadjusted Pensionable Earnings (DUPE)—is automatic once either party applies, cannot be reversed, and operates outside the normal property-equalization rules. This guide explains every rule change effective in 2025, demonstrates how CPP pension splitting and the enhanced CPP2 tier affect higher earners, and provides step-by-step instructions for protecting your long-term financial security.
The Big Picture
- Automatic but not self-executing: Credits are split only after a formal application, yet once processed the reallocation is permanent and courts cannot undo it^1.
- Ontario’s non-waiver rule: Unlike Alberta, B.C., Saskatchewan, Quebec, and a handful of pre-1986 agreements in Manitoba, Ontario spouses cannot contract out of CPP credit splitting^2.
- Two-tier contributions for 2025:
- Timing matters: Married couples can apply at any time (unless the ex-spouse dies—then a 36-month limit applies). Common-law partners have 48 months to file unless both sign a waiver extending the deadline^1.
- Processing speed: Service Canada averages 6-12 weeks to render a decision, while each party has 30 days to dispute the other’s submitted facts^7.

CPP splitting evenly divides pensionable earnings accumulated during a marriage or common-law relationship
The Canada Pension Plan (CPP) credit splitting process involves calculating the total pensionable earnings that both partners accumulated during their time living together. The combined credits are then divided equally between both parties, regardless of who earned more during the relationship. This process, also known as CPP credit division, creates a permanent reallocation that can’t be reversed.
- Total up all CPP contributions made by both partners during cohabitation
- Divide the combined pensionable earnings by two
- Reallocate credits equally to each person’s CPP record
- Apply adjustments to each partner’s future CPP benefits
CPP credit splitting can provide significant financial benefits for lower-income spouses after separation or divorce
CPP credit splitting (also known as credit sharing) allows couples who are separated or divorced to equally divide the Canada Pension Plan credits they accumulated during their relationship. This process can be particularly advantageous for partners who earned less or took time away from work for family responsibilities.
The benefits of CPP splitting include:
- Increased pension benefits for the lower-income spouse
- Fair distribution of retirement savings accumulated during the relationship
- Potential qualification for benefits that might otherwise be unavailable
- No cost to apply for credit splitting
While the higher-earning spouse may see a reduction in their CPP benefits, the splitting process ensures a more equitable distribution of pension credits earned during the marriage or common-law relationship. The decision is typically most beneficial when there was a significant income disparity between partners.
CPP credit splitting is mandatory in Ontario following divorce or separation, but can be waived by mutual agreement.
The Canada Pension Plan (CPP) credit splitting process automatically divides pension credits earned during a marriage or common-law relationship when it ends. This division applies to couples in Ontario who separate or divorce, unless both parties specifically agree in writing to opt out.
- Credits are split equally for the period of cohabitation
- Both former spouses must apply to Service Canada within 48 months of separation
- The split applies even if one spouse never contributed to CPP
- Credit splitting cannot be reversed once approved
This mandatory provision helps ensure financial fairness by recognizing both partners’ contributions to the relationship, whether through paid employment or unpaid domestic responsibilities.
Ex-spouses can claim a share of CPP credits earned during the marriage through credit splitting
Under Canadian law, Canada Pension Plan (CPP) credits accumulated during a marriage or common-law relationship can be equally divided between former partners through a process called CPP credit splitting. This division applies regardless of who made the contributions.
- Credit splitting is available after divorce, legal separation, or end of a common-law relationship
- Either former spouse can apply for credit splitting within 48 months of separation
- The split applies only to credits earned while living together
- Once approved, the division is permanent and cannot be reversed
This process helps ensure fair pension distribution, particularly for spouses who may have reduced their work hours or left employment to care for family during the relationship.
CPP credits earned during marriage can be equally split between divorcing spouses through credit splitting
When couples divorce in Canada, the Canada Pension Plan (CPP) credits accumulated by both partners during their marriage or common-law relationship can be divided equally through a process called CPP credit splitting. This division occurs regardless of which spouse made the contributions.
The credit split can affect:
- Future CPP retirement pension amounts
- CPP disability benefits
- CPP survivor benefits
- Children’s benefits
To initiate credit splitting, either spouse can apply through Service Canada. The split applies only to credits earned while living together, and once approved, this division is permanent and cannot be cancelled, even if both parties agree.
