What probate actually costs in Ontario
Executors usually budget for the tax and are blindsided by everything around it.

How much is probate in Ontario?
Ontario charges an estate administration tax on the value of the estate, with the first tranche exempt and a flat rate applied to the value above it. It is charged on assets passing through the estate only — jointly held property with right of survivorship, and assets with a named beneficiary such as registered accounts and life insurance, generally pass outside it. Our calculator carries the current rate and exemption with the date they were verified.
The tax is charged on the estate, not on everything the person owned
This distinction decides most of the bill, and it is where planning happens.
Assets that pass outside the estate are not counted. Property held in joint tenancy with right of survivorship passes to the survivor automatically. Registered accounts and life insurance with a named beneficiary pass directly to that beneficiary. Assets in certain trusts likewise sit outside.
What remains — solely held property, bank accounts without a beneficiary designation, investments in a personal name — forms the estate the tax is calculated on.
This is why two people with identical net worth can face very different probate bills.
Planning around it has real trade-offs
Because the base is avoidable, a whole industry exists to reduce it. Each technique carries costs the tax saving may not justify.
Adding an adult child as a joint owner of a property removes it from the estate — and exposes it to that child's creditors, their divorce, and a potential capital gains liability, while raising the legal question of whether it was a gift or held in trust. That litigation is not rare.
Beneficiary designations are cleaner but need reviewing after every major life change. A designation naming a former spouse survives the relationship unless it is changed.
The saving is a percentage of the estate value. Weigh it against what the arrangement costs in flexibility and risk.
The delay costs more than the tax
Executors consistently underestimate the time rather than the money.
Until a certificate of appointment issues, a financial institution will generally not release funds, a house cannot be sold, and investments cannot be transferred. The estate is frozen while bills — property tax, insurance, utilities, mortgage — continue.
Processing times vary considerably by court location and by how complete the application is. An incomplete filing goes to the back of the queue, so accuracy first time matters more than speed of submission.
Executors often need to fund carrying costs personally in the interim and be reimbursed later.
Valuation is the executor's problem, and it is a legal duty
The tax is calculated on the value of the estate as at the date of death, and the executor is personally responsible for the accuracy of that figure.
Real property needs a defensible valuation. So do private company shares, collections and anything else without a market price. Estimating low to reduce the tax is a poor idea: an estate information return is required after the certificate issues, and the Ministry of Finance can assess the estate and hold the executor accountable for an understatement.
Get appraisals for anything material and keep the documentation.
Executor liability is personal. That is reason enough to do the valuation properly rather than quickly.
Not every estate needs probate at all
Probate is not automatically required. It is required when someone — usually a bank, a land registry or a transfer agent — needs proof of the executor's authority.
A small estate held entirely in joint accounts, with a home in joint tenancy and registered accounts carrying beneficiary designations, may pass without any application. Ontario also has a simplified procedure for small estates below a threshold.
Whether it is needed depends on what the estate holds and on the policies of the institutions involved, which can differ.
Ask each institution what it requires before assuming a full application is necessary.
