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

Oakville, about 214,000 residents, is one of Ontario's most affluent communities, with high home values and many executives and business owners. For estates of this size, the 1.5% probate tax is a real number — and planning pays off.
What a valid will requires in Oakville
Under the Succession Law Reform Act, an Oakville 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 is valid without witnesses; fully electronic wills aren't clearly valid — print and sign.
Probate and cost in Oakville
Oakville estates are probated through the Ontario Superior Court of Justice for Halton Region (Milton). Ontario's Estate Administration Tax is about 1.5% above $50,000 — roughly $14,250 on a $1,000,000 estate, and more for the larger estates common in Oakville. Beneficiary designations, joint tenancy where appropriate, multiple wills for business owners, and sometimes trusts can keep significant value out of probate.
If you die without a will in Oakville
Intestacy gives a married spouse the first $350,000 plus a share, and a common-law partner nothing. For higher-value, blended-family estates, the default formula rarely matches intentions — a will is essential.
Getting started
Given typical Oakville estate values, many residents benefit from a lawyer's advice; simpler estates can still use a reputable Ontario online will signed with two witnesses. Add Powers of Attorney for Property and Personal Care.
