It forms part of that spouse's estate, but family law rights and an equalisation election can still reach it.
The Canadian position
It forms part of that spouse's estate, but family law rights and an equalisation election can still reach it.
Provincial law governs the detail, so confirm the position where the estate will be administered.
The Islamic position
The fixed shares apply to the net estate after funeral expenses, debts and any bequest capped at one third.
Where a Canadian instrument has no classical counterpart, treat it as a contemporary question for a qualified scholar.
Where the four schools differ
This question turns on one issue in our madhhab register: Marital property and the estate — what part of the marital property was the deceased’s to leave?

Contemporary, not classical. Two recognised bodies have addressed money the spouses built up together; neither has adopted a statutory matrimonial-property regime as such, and that is itself the finding. The International Islamic Fiqh Academy (Resolution 144 (16/2), 16th session, Dubai, 9–14 April 2005) put separate estates first: “the wife has full legal capacity and a complete, independent financial personality … the husband has no authority over her property”. Its sixth head is the one that bites: “if the wife has actually contributed, out of her own property or the earnings of her work, to the acquisition of a dwelling, a property or a commercial venture, she has a right to share in the ownership of it in proportion to the money she contributed”. That is proportionate co-ownership on proof of contribution — not an equal division, and not a rule about death. The Assembly of Muslim Jurists of America, in the recommendations of its 20th Annual Imams’ Conference (2024), goes to the death case under the name haqq al-kadd wa’l-si‘aya, the right of effort and contribution: it is “not determined as a fixed portion, such as half or a third” but assessed on what she actually put in; housework is expressly outside it; and “the wife’s right to kadd wa-si‘ayah is fulfilled from her deceased husband’s estate, along with the settlement of his debts, and before executing any wills or distributing the inheritance”. So a contribution claim is handled as a debt-level charge on the estate, ahead of the shares — but its size has to be proved, and no body reviewed here converts it into a fixed fraction.
