Making a Will in Mississauga, Ontario
Last updated 2026-06 · Ontario

Mississauga, with around 718,000 residents, is one of Canada's most diverse cities — and many newcomer families assume their home-country rules carry over. They don't: Ontario law governs every will made here.
What a valid will requires in Mississauga
Under the Succession Law Reform Act, a Mississauga will must be in writing, signed at the end, and witnessed by two non-beneficiary adults present together. You must be 18 and capable. A fully handwritten holograph will needs no witnesses, but it's the riskiest form. Fully electronic wills aren't clearly valid in Ontario — print and sign.
Probate and cost in Mississauga
Mississauga estates are probated through the Ontario Superior Court of Justice serving Peel Region (Brampton courthouse). Ontario's Estate Administration Tax runs about 1.5% above $50,000 — roughly $14,250 on a $1,000,000 estate. With Mississauga's high property values, beneficiary designations on registered accounts and insurance, plus joint tenancy where appropriate, can trim the probated estate substantially.
If you die without a will in Mississauga
Ontario intestacy gives a married spouse the first $350,000 plus a share; a common-law partner inherits nothing. Blended and multigenerational households — common in Mississauga — especially need a will to avoid an unintended split.
Getting started
A simple estate can use a reputable Ontario online will signed with two witnesses; blended families, businesses, or larger estates should see a lawyer. Add Powers of Attorney for Property and Personal Care.
