National guide. Then pick a province: legal propositions live in the 26 packs, not in this essay.

A Canadian marriage contract is a provincial (or territorial) domestic contract between people who are married or about to marry. It is not a U.S. prenuptial agreement under the Uniform Premarital Agreement Act, and it is not a Swedish äktenskapsförord. The federal Divorce Act can still matter later for support. Property defaults live in provincial statutes, and those statutes do not match each other.

Ontario equalization, British Columbia family property, Alberta family property, and Québec family patrimony are four different machines. A clause that waives 'community property' is the wrong story in most of Canada. A clause that tries to opt out of Québec family patrimony is asking a public-order question that Ontario s. 56(4) will not answer. First-class coverage in this product means every province and territory has its own marriage-contract pack rather than a national template with a dropdown.

Formality also splits. Ontario, Prince Edward Island, and Newfoundland and Labrador lean on written, signed, witnessed domestic contracts. Québec marriage contracts are typically notarial acts. Several Western and territorial statutes mix writing with acknowledgement language of their own. Independent legal advice letters are common evidence in common-law Canada; they are not a uniform statutory certificate, and they are not a notaire’s counseling model.

Common questions

Is a Canadian marriage contract the same as a prenup?

In conversation, people say prenup. In this catalog the instrument is a marriage contract (or Québec contrat de mariage). Formation, setting-aside, and the default property regime are provincial. Do not import California waiting periods or Skatteverket registration.

Can one national contract cover a couple who might move?

A governing-law clause is a conflicts question for a lawyer, not something this product decides. If the couple later lives in another province, a court may still look at that province’s family-property statute. Each live pack stays inside its own cited Act.

Does Québec play by the same opt-out rules?

No. Family patrimony is of public order. Spouses choose or default into a matrimonial regime (often partnership of acquests) by marriage contract, but they do not simply waive family patrimony the way an Ontario couple might contract around equalization.

What about the matrimonial or family home?

Most provinces give the home special possessory or accounting treatment. A blanket 'the house stays mine' clause is often the wrong question. Read the province pack’s property and limitations sources instead of assuming Texas homestead or Swedish samboegendom.

Can we waive child support?

Treat any child-support or parenting waiver as a lawyer issue. These packs catalogue that children are not ordinary contract subjects. They do not invent a federal child-support guideline result.

Does independent legal advice make the contract bulletproof?

No. ILA is often important evidence on understanding and fairness. It is not automatic validity. Missing ILA is not automatic invalidity. Québec notarial form is a different professional model.

Worked examples

An American 'prenup' PDF used for an Ontario wedding

If the file recites UPAA, community property, and a California notary block, the Ontario questions are still FLA domestic-contract form, equalization, and the matrimonial home. The product should not translate those U.S. labels into Ontario results.

A Québec couple who want to 'opt out of everything'

Family patrimony and the legal regime are not an Ontario-style waiver exercise. The notarial marriage contract and public-order limits are the sourced questions. English marketing copy that says prenup does not change the Code.

A BC marriage agreement signed a week before the wedding

Timing is a voluntariness and s. 93 / Hartshorne-style fairness fact, not a U.S. waiting-period checkbox. The pack will not declare the agreement void because it was late.
