How Are CPP Credits Split After Divorce?

Contributions made by both spouses during the years they lived together are added up and divided equally, on application to Service Canada. The division applies to the pensionable earnings themselves, not to a pension already in payment, and it can be requested years after the separation.

60-SECOND ANSWER

CPP credits earned during cohabitation are divided equally on application, regardless of who made the contributions.

The answer:: Pensionable earnings from the years of cohabitation are totalled and split equally between the two records.
The trap:: Assuming a separation agreement can waive it. Only certain provinces permit a valid waiver, and a federal agreement alone does not.
The recommendation:: Apply even if the marriage was short, because the calculation is done on the actual records rather than an estimate.

Where the AI summary above gets this wrong

"CPP is split fifty-fifty in a divorce settlement."

That's surface-true. Here's what it misses:

It splits credits, not payments — The division applies to the pensionable earnings recorded for each year, which then flow through the ordinary benefit calculation.
Only cohabitation years are divided — Contributions before the relationship began and after separation stay with the person who made them.
A waiver is not always possible — Provincial family law determines whether a couple can contract out, and several provinces do not permit it.

01 What is actually divided

The division applies to pensionable earnings, not to a pension amount. Service Canada totals the earnings recorded for both spouses in each year of cohabitation and assigns half of that total to each record.

The revised records then flow through the normal benefit calculation, so the effect on an eventual pension follows from each person's whole contribution history rather than from the split alone — the underlying calculation is in the maximum versus average CPP.

02 Who gains and who loses

The lower earner gains and the higher earner loses, which is the point. A spouse who left the workforce to raise children has years of low or nil earnings that the division fills in from the other record.

The loss to the higher earner is often smaller than expected, because their own dropout provisions may already exclude some of the affected years. It is still a real reduction, and it is permanent.

03 Whether it can be waived

The division is available on application by either former spouse, and does not require the other's consent. Whether a separation agreement can validly waive the division is a question of provincial family law rather than of federal legislation.

Several provinces permit an express waiver in a written agreement and several do not, so a clause purporting to waive the split may have no effect. The application can be made long after the separation, subject to time limits for common-law partners.

For a common-law relationship the application also carries a time limit measured from separation, which married couples do not face in the same way. That deadline is the reason a former partner should apply on their own rather than waiting for the other side to raise it.

The waiver question is where the real cost sits. Lawyers write the clause, both parties sign, and years later one of them discovers the province in question never allowed it. Whether the split can be given up is not a matter the agreement decides on its own.
