High-asset separation in Ontario

The law is the same for every Ontario family, but a high-asset separation tests it harder. More of the work is valuation (businesses, professional practices, investments, pensions and trusts), disclosure goes deeper into corporations and trusts, expert reports follow strict court rules, and support often moves past the ordinary formulas, with child support over $150,000 and spousal support above the $350,000 guideline ceiling. Many of these cases settle, or go to private family arbitration, rather than to trial.

How a high-asset separation usually unfolds, step by step

The basic property rules are on our property division page: each married spouse's net family property is calculated on the valuation date, and the spouse with more pays half the difference (Family Law Act, s. 5(1)). What changes with substantial wealth is the effort needed to reach reliable numbers and the strategy for paying.

Secure the facts early. Identify every entity, account, policy and property, in Canada and elsewhere. Rule 13(3.3) of the Family Law Rules requires, among other things, three years of financial statements for a sole proprietorship or practice, a partnership agreement and partnership statements, share information for every corporation and, for a privately held corporation, three years of its and its subsidiaries' statements, plus corporate tax returns for a majority interest, and trust settlement agreements with three years of trust statements (paras. 5 to 9).
Fix the valuation date and the wedding-day picture. The valuation date is usually the separation date (s. 4(1)). Proving what each spouse owned at the wedding, especially in a business that has grown, can be worth a great deal, and the spouse claiming a deduction must prove it (s. 4(3)). Our page on the valuation date covers how it is set.
Retain the right advisers. Business valuators, income analysts and sometimes actuaries or tax advisers. A litigation expert's duty to the court is to give fair, objective and non-partisan opinion evidence, and that duty prevails over any obligation to the party who hired them (r. 20.1(2) and (3)). A party who wants to call one at trial must serve the expert's signed report at least six days before the settlement conference (r. 20.2(2)).
Deal with tax as part of value. Net family property deducts "any applicable contingent tax liabilities" (s. 4(1.1)). Shares, investments and registered plans each carry a different tax profile, so two assets with the same face value may not be worth the same.
Work out income for support. Corporate income can be counted under s. 18 of the Child Support Guidelines, and child support above $150,000 follows s. 4. Spousal support above a payor income of $350,000 is decided case by case.
Protect what matters while the case runs. If assets are at risk, a preservation order can be sought (s. 12). Our page on preservation orders explains the process in Toronto.
Choose the forum. Negotiation, mediation, family arbitration or the Superior Court of Justice. In Toronto, the court sits at 361 University Avenue for family matters.

Where high-asset cases differ from ordinary ones

Issue	What is different	Main rule
Operating business or professional practice	Formal valuation; the court avoids ordering a sale or seriously impairing operations if there is a reasonable alternative	Family Law Act, s. 11
Disclosure	Corporate, partnership and trust documents for three years	Family Law Rules, r. 13(3.3), paras. 5 to 9
Expert evidence	Signed reports served at least six days before the settlement conference; duty to the court	r. 20.1 and 20.2
Contingent tax	Deducted where applicable	Family Law Act, s. 4(1.1)
Payment of equalization	Instalments up to ten years only to avoid hardship; security; share of profits or shares in a corporation	ss. 9 and 11(2)
Child support	Table amount unless inappropriate above $150,000	Child Support Guidelines, s. 4
Corporate income	All or part of pre-tax corporate income may be counted	Child Support Guidelines, s. 18
Spousal support	Formulas not automatic above $350,000 payor income	SSAG, chapter 11
Family arbitration	Award enforceable only if agreement is in writing, each party had independent legal advice, and other conditions are met	Family Law Act, s. 59.6

What changes the answer

A marriage contract. Property the spouses agreed in a domestic contract to exclude is not part of net family property (s. 4(2), para. 6), and a domestic contract generally prevails over the Act (s. 2(10)). A contract can be set aside in limited circumstances, including failure to disclose significant assets or debts (s. 56(4)). Our page on setting aside a marriage contract or separation agreement explains the grounds.
Gifts and inheritances. Family wealth received from a third party during the marriage, and property traceable to it, is excluded unless it went into a matrimonial home (s. 4(2), paras. 1 and 5). Our page on excluded property covers proof and tracing.
Trusts. A spouse who is a beneficiary must disclose the trust settlement agreement and three years of the trust's statements (r. 13(3.3), para. 9). For support, a court may impute income where a spouse receives or will receive income or benefits from a trust (Child Support Guidelines, s. 19(1)(i)).
Property outside Ontario. Spouses' property rights arising from the marriage are governed by the law of their last common habitual residence, or Ontario law if there was none (Family Law Act, s. 15). Where Ontario law applies, assets abroad still count in net family property, but enforcement can need steps elsewhere.
Conduct with assets. Intentional or reckless depletion, bad-faith debts or undisclosed marriage-date debts can support an unequal division if equalizing would be unconscionable (s. 5(6)). Our page on unequal division explains the high bar.
Private resolution. The Justice Canada user's guide to the Spousal Support Advisory Guidelines notes that many high-income cases in Ontario are resolved by arbitration or mediation-arbitration. A family arbitration agreement is unenforceable unless made after the dispute has arisen (s. 59.4).

A worked example

For example, imagine Priyanka and Mark separate after 16 years. This is a hypothetical. Mark owns 70 percent of an engineering firm through a holding company; Priyanka is a partner in a Bay Street accounting practice. They own a home in Rosedale, a cottage in Muskoka, investment accounts and RRSPs, and Priyanka has an inheritance from her grandmother held in a separate account.

Disclosure: Mark serves three years of statements for the operating and holding companies and the corporate tax returns; Priyanka serves her partnership agreement and three years of partnership statements (r. 13(3.3), paras. 6 to 8).
Valuation: each side retains a valuator for Mark's shares, including a wedding-day value; the reports are served at least six days before the settlement conference (r. 20.2(2)).
Exclusions: Priyanka's inheritance may be excluded if she received it after the marriage, can trace it, and it never went into a matrimonial home (s. 4(2)). If the cottage was ordinarily occupied as a family residence at separation, it may be a second matrimonial home with no wedding-day deduction (ss. 4(1) and 18(1)).
Payment: if Mark owes equalization, s. 11 points away from forcing a sale of the firm, so the parties look at the investments, a transfer of the cottage, or secured instalments if paying at once would cause hardship (s. 9(1)).
Support: if both incomes are high and there are no dependent children, spousal support may be modest or nil; if there are children, child support for income over $150,000 is calculated first.

The facts are invented. The pattern is typical: the legal rules are familiar, but the evidence behind each number is where the work lies.

Common mistakes in high-asset separations

Relying on book values. Accounting statements are not market values; a business or practice usually needs a valuation.
Ignoring tax. Two assets of equal face value can differ widely after contingent tax.
Late expert reports. Missing the six-day deadline before the settlement conference can limit what the expert may later say (r. 20.2).
Losing the wedding-day deduction. Without proof of marriage-date values, the deduction can be lost (s. 4(3)).
Moving money between companies after separation. It can invite a preservation order and can damage credibility.
Arbitration without the formalities. An award may not be enforceable if the agreement is not in writing or a party lacked independent legal advice (s. 59.6).

What to do this week

Make a list of every company, partnership, trust, property and account you or your spouse has an interest in.
Ask your accountant to assemble three years of statements and tax returns for each entity.
Search for marriage-date evidence: early statements, share registers, purchase agreements.
Find any marriage contract or cohabitation agreement and any independent legal advice certificates.
Avoid restructuring companies, paying unusual dividends or moving money until you have advice.
Book a free consultation to plan disclosure, experts and the forum before the first exchange of documents.

Frequently asked questions

Is my business divided in half?

No. Its value (less any wedding-day value and contingent tax) goes into your net family property. The business itself usually stays with you, and s. 11 directs the court away from a sale if there is a reasonable alternative. Our page on a business owned by one spouse explains valuation.

Do I need a business valuator?

Usually, when a significant business or practice is involved. A court-appointed expert is also possible under rule 20.3, and joint experts can reduce cost.

Is spousal support capped for high earners?

No. The $350,000 ceiling is where the formulas stop applying automatically, not a cap. Our page on spousal support above the guideline ceiling explains it.

Can we keep our case private?

Family arbitration is a private process governed by the Family Law Act and the Arbitration Act, 1991 (s. 59.1). It has formal requirements for the award to be enforceable (s. 59.6).

How is income from a holding company treated for child support?

Under s. 18 of the Child Support Guidelines, the court can include pre-tax income of the corporation and related corporations. Our page on corporate income and support explains how.

How do we split RRSPs and investments without triggering tax?

Registered plans can be transferred directly between spouses under an order or written separation agreement. Our page on RRSPs, TFSAs and investments sets out the rules.
