One of the most misunderstood parts of Ontario property division: what happens to RRSPs and TFSAs in a divorce.
The common fear is that your entire retirement savings are on the table. The common misconception on the other side is that registered accounts are somehow protected. Both are wrong. The reality is more nuanced — and the details can shift the numbers significantly.
Ontario doesn't split assets 50/50. It equalizes the growth in each spouse's net worth during the marriage. RRSPs and TFSAs are included in that calculation, but only the portion that grew during the marriage. What you had before you married? That's yours to deduct — if you can prove it.
The Short Version
Are they divided? Yes — included in Net Family Property for married spouses
Is it 50/50? No — only the growth during the marriage is equalized, not the total balance
The gotcha: You need your RRSP and TFSA statements from your wedding day to claim the premarital deduction. No records = no deduction
Common law? No automatic rights to each other's RRSPs or TFSAs
How Ontario Property Division Actually Works
To understand RRSP and TFSA division, you first need to understand the Ontario equalization framework. This applies only to legally married spouses — common-law couples are handled differently and are covered below.
Ontario's Family Law Act is built on the idea that marriage is a financial partnership. When it ends, the law equalizes the growth in each spouse's net worth during the marriage — not the assets themselves, but the increase in value that happened while the partners were together.
Each spouse calculates their Net Family Property (NFP) using the same formula:
Minus Debts at date of separation
Minus Assets owned at the date of marriage
Minus Excluded property (qualifying gifts and inheritances)
The equalization payment is half the difference between the two spouses' NFPs. The spouse whose net worth grew more during the marriage pays the other half the gap.
RRSPs and TFSAs are included in this calculation as assets at the date of separation. But — and this is the part that matters — the value you had in those accounts on your wedding day can be deducted from your NFP. Only the growth that happened during the marriage enters the equalization.
RRSPs: What Gets Divided, What Doesn't
The Premarital Deduction
If you had an RRSP before you married, the value of that RRSP on your wedding day is deducted from your NFP. You've already established it — you can't be expected to share it with a spouse who had nothing to do with accumulating it.
The growth that happened during the marriage is a different story. That growth occurred while you were in the financial partnership of marriage, and it enters the equalization calculation.
Example: The RRSP Premarital Deduction
On the day James married, his RRSP was worth $40,000. At the date of separation, it is worth $190,000.
Without the deduction: The full $190,000 enters his NFP.
With the deduction: James deducts the $40,000 premarital value. Only $150,000 — the growth during the marriage — enters his NFP.
The difference: If James is entitled to this deduction, his NFP is $40,000 lower — which changes the equalization payment by $20,000 (half the difference goes to his spouse). That's real money. And it only works if James can prove what his RRSP was worth on his wedding day.
The Records Problem
Here's where people get hurt. To claim the premarital deduction for an RRSP, you need to be able to prove what that RRSP was worth on the date of your marriage. That means account statements from around the time you got married.
Most people don't have those statements. They're from years ago, sometimes decades ago. Banks and financial institutions typically only keep records for up to 7 years — after that, the data is often gone permanently. If you can't produce the documentation, you may not be able to claim the deduction — meaning the full current value of your RRSP enters your NFP instead of just the growth.
What to look for:
- Annual RRSP statements from the year you married (or the closest available)
- Old tax returns, which sometimes show RRSP contribution history and balances
- Contact your financial institution directly — some can retrieve historical account data further back than what's available online
TFSAs: The Same Rules Apply
TFSAs are treated the same way as RRSPs under Ontario's Net Family Property framework — they are included in the assets-at-separation calculation, and the premarital balance can be deducted.
TFSAs were introduced in 2009. If you married before 2009, any TFSA balance at the date of marriage would be zero — since TFSAs didn't exist yet — and the full balance at separation would enter your NFP. If you married after 2009, the date-of-marriage TFSA balance can be deducted, provided you have the statements to prove it.
Example: TFSA and NFP
Kim and David married in 2015. At the date of marriage, Kim had $12,000 in her TFSA. At the date of separation, her TFSA is worth $48,000.
With the deduction: Kim deducts the $12,000 premarital TFSA balance. Only $36,000 — the growth during the marriage — enters her NFP.
The requirement: Kim needs a TFSA statement from around the time of their 2015 marriage to prove the $12,000 figure. Without it, the full $48,000 enters her NFP.
What You Need to Document
For both RRSPs and TFSAs, financial disclosure in an Ontario divorce requires statements from two key dates:
| Document | Date of Marriage | Date of Separation |
|---|---|---|
| RRSP statements | To establish premarital value (deductible) | To establish current NFP value |
| RRIF statements | If RRSP was converted before marriage | To establish current NFP value |
| TFSA statements | To establish premarital value (deductible) | To establish current NFP value |
| Other investment accounts | All accounts must be disclosed | All accounts must be disclosed |
| Pension statements | If applicable | Required — valuation often complex |
Both parties have an obligation to make full financial disclosure. Failing to disclose accounts — including registered accounts — can be grounds to set aside a separation agreement entirely. If you later discover your spouse had RRSPs or TFSAs they didn't disclose during negotiations, you have grounds to challenge any agreement reached without that information.
RRSPs vs. TFSAs: Is There a Difference in How They're Treated?
Under Ontario's NFP framework, both are included as assets at the date of separation and both have the premarital portion deducted. The equalization calculation treats them similarly.
The practical difference is in the records. TFSAs are newer — if you've been married since before 2009, the date-of-marriage TFSA balance is zero by definition and there's no deduction to claim or document. For RRSP holders who were married before, say, 2005, tracking down 20-year-old statements is genuinely difficult and sometimes impossible.
Neither account type is "protected" from the equalization calculation. The idea that registered accounts are off-limits in divorce is a common misconception. They are not. They are assets with a value at the date of separation, and that value — net of any provable premarital balance — is part of the equalization.
Pensions: Also Property, but More Complex
While this article focuses on RRSPs and TFSAs, it's worth flagging that pensions are also treated as property under Ontario's equalization framework. A pension earned during the marriage has a value at the date of separation, and that value must be calculated and included in the owning spouse's NFP.
Pension valuation is significantly more complex than RRSP or TFSA valuation. It typically requires professional actuarial analysis — you can't simply use the current account balance as you would with an RRSP, because pension entitlements don't work the same way. If either spouse has a significant pension, professional advice is strongly recommended before any agreement is reached.
There is also a concept called "double dipping" that arises when a pension is divided as property through equalization and then also treated as income for spousal support purposes. Courts generally try to avoid this — focusing support on the portion of the pension not included in equalization — but in some needs-based situations, some overlap may be unavoidable.

The Common-Law Situation: No Automatic Rights
Everything above applies only to legally married spouses. Common-law partners in Ontario have an entirely different — and significantly weaker — set of property rights.
Common-law partners have no automatic right to share in each other's RRSPs or TFSAs. Ontario's Net Family Property equalization regime does not apply to them. When a common-law relationship ends, each partner generally keeps what is in their own name — including registered accounts held in their name.
A common-law partner might pursue an unjust enrichment claim if they contributed substantially to the other's wealth in a way that would be unfair to ignore. But this requires litigation, is uncertain in outcome, and is evaluated on the specific facts — not a formula.
The only way for common-law partners to establish clear rights to each other's RRSPs or TFSAs in advance is through a cohabitation agreement that specifically addresses registered accounts. Without one, those accounts belong to whoever's name is on them.
RRSP and TFSA Division vs. Spousal Support: Two Separate Things
A common question: if my ex gets a share of my RRSP through equalization, does that affect spousal support?
Equalization and spousal support are two independent calculations. One does not automatically reduce the other. They are determined separately, based on different factors.
That said, there can be some interaction in practice. A spouse who receives a substantial equalization payment — including a significant share of retirement savings — may be expected to generate investment income from those assets. Courts can consider that when assessing ongoing need for spousal support. But there is no formula that automatically reduces support because equalization happened.

Use the Property Division Calculator
Our property division calculator walks through the NFP formula with your actual numbers — including RRSP, TFSA, and other asset values at both dates. It gives you a baseline equalization estimate before you sit down with a lawyer.
Note: the property division calculator does not include pensions, which require professional valuation. If either spouse has a significant pension, the calculator's result will be incomplete — use it as a starting point, not a final answer.
Frequently Asked Questions
Are RRSPs divided in an Ontario divorce?
Yes, but not necessarily 50/50. In Ontario, RRSPs are included in the Net Family Property calculation. Only the growth in the RRSP during the marriage is part of the equalization — the amount you had in your RRSP on your wedding day can be deducted. You'll need your RRSP statements from the date of marriage to claim that deduction.
Are TFSAs divided in an Ontario divorce?
Yes. TFSAs are included in the Net Family Property calculation the same way RRSPs are. The premarital value of a TFSA can be deducted from NFP, meaning only the growth during the marriage is equalized. As with RRSPs, you need statements from your wedding date to prove the deduction.
Does my ex get half my RRSP in a divorce?
Probably not exactly half. Your RRSP is included in your Net Family Property, but Ontario's equalization system divides the growth in each spouse's net worth during the marriage — not the assets themselves 50/50. What your ex is entitled to depends on both spouses' full NFP calculations. The premarital portion of your RRSP is deducted before equalization.
What documents do I need for RRSP division in a divorce?
You need RRSP and RRIF statements from two dates: the date of separation and the date of marriage. The date-of-marriage statement is often the hardest to track down. You also need statements for any other accounts — TFSAs, bank accounts, investments, and pension information — as of both dates. If you can't prove what your RRSP was worth on your wedding day, you may lose the right to deduct that premarital value.
Do common-law partners split RRSPs and TFSAs in Ontario?
No — not automatically. Ontario's Net Family Property equalization regime applies only to legally married spouses. Common-law partners have no automatic right to share in each other's RRSPs or TFSAs. A common-law partner might pursue an unjust enrichment claim in some circumstances, but there is no automatic entitlement. A cohabitation agreement can establish RRSP or TFSA rights in advance.
