Is a Will Drafted in Alberta or BC Valid in Ontario?

💡

Generally, a will drafted and properly witnessed in another Canadian province, such as Alberta or British Columbia, is legally valid in Ontario. However, to probate the document, the Ontario Superior Court of Justice will usually require an Affidavit of Execution from the original out-of-province witnesses, which can cause severe delays if those witnesses cannot be located.

Canadians move across the country every day. If you recently relocated from Calgary or Vancouver to start a new life in Ontario, you might be wondering if your estate plan made the journey with you. 🚚 It is a common misconception that crossing provincial borders automatically invalidates your legal documents. Under the Ontario Succession Law Reform Act, inter-provincial estate planning is highly respected, but it is not entirely seamless.

While your Alberta or BC will is likely valid, the administrative reality of using an out-of-province document can be a nightmare for your loved ones. Whether you have settled in Toronto, Hamilton, or London, differences in probate taxes, executor bonding requirements, and witness affidavits can slow down your estate administration. This guide explores cross-provincial estate law and why consulting a local Ontario lawyer from our directory to update your will is often the smartest choice.

Step-by-Step Process for Out-of-Province Wills in Ontario

If an executor needs to use an Alberta or BC will to manage an estate in Ontario, they must follow specific procedures to satisfy the local courts. Here is the step-by-step process of how inter-provincial wills are handled.

Step 1: Confirm the Formal Validity of the Will

Ontario law states that a will is valid as long as it was executed in compliance with the laws of the province where it was signed. 🔍 For example, if you lived in British Columbia and signed your will perfectly according to the BC Wills, Estates and Succession Act (WESA), Ontario will generally recognize it as a legally binding document.

Step 2: Locate the Affidavit of Execution

This is the most common stumbling block. To apply for probate in Ontario, the Superior Court of Justice requires an Affidavit of Execution-a sworn statement by one of the witnesses who watched you sign the will. If your Alberta lawyer did not draft and attach this affidavit years ago, your executor will have to track down those original witnesses in Alberta, which can take months and cost thousands in private investigator fees.

Step 3: Assess Executor Bonding Requirements

If your named executor still lives in BC or Alberta, they may face hurdles in Ontario. An out-of-province executor applying for a Certificate of Appointment of Estate Trustee in Ontario is sometimes required by the court to post an administration bond. 💰 This acts as insurance to protect the estate, though an Ontario judge can dispense with this requirement if all beneficiaries consent in writing.

Step 4: Consult an Ontario Estate Lawyer

Even if the will is valid, your executor should consult a local Ontario estate lawyer. The lawyer will review the terminology used in the western province’s will to ensure it does not conflict with Ontario family law (such as equalization claims for spouses) or real estate property laws.

Step 5: Draft a New Ontario Will if Necessary

Given the administrative headaches of witness affidavits and out-of-province executors, the most highly recommended step is to simply draft a new will in Ontario. 📝 Drafting a fresh document under Ontario jurisdiction ensures a smooth, localized probate process for your family when the time comes.

How Much Does it Cost in Ontario?

Managing an out-of-province will can sometimes cost more in legal administration than simply drafting a new one upon your arrival in Ontario.

  • Drafting a New Ontario Will: A straightforward new will in Ontario generally costs between $400 and $800 CAD.
  • Tracking Down Witnesses: If an Affidavit of Execution is missing from an old BC will, hiring a lawyer or investigator to find the witnesses out West can easily cost $1,000 to $3,000+ CAD.
  • Administration Bond: If the out-of-province executor is required to post a bond, premiums can cost thousands of dollars, paid directly from the estate.

How Long Does the Process Take?

Using an out-of-province will often extends the timeline of estate administration due to extra verification steps.

  • Reviewing the Will: An Ontario lawyer can review your Alberta or BC will for validity in just a few days.
  • Probate with a Valid Affidavit: If the out-of-province will has a perfect Affidavit of Execution, applying for probate takes the standard 4 to 8 months.
  • Drafting a Replacement Will: Securing a fresh, Ontario-compliant estate plan takes only 2 to 4 weeks and saves significant future delays.

Frequently Asked Questions (FAQ)

Do I have to pay probate taxes in both Ontario and Alberta?

Generally, no. You typically apply for probate in the province where the deceased ordinarily resided at the time of death. However, if you own real estate (land) in Alberta, you may need an ancillary probate grant in Alberta just for that property.

Can an Alberta lawyer apply for probate in Ontario?

No. Lawyers must be licensed by the Law Society of Ontario to practice law and apply to the Superior Court of Justice in Ontario. Your executor will need to hire local Ontario counsel.

Are BC holograph (handwritten) wills valid in Ontario?

Yes. Ontario recognizes holograph wills (wills written entirely in your own handwriting and signed, without witnesses). If your handwritten BC will meets those standards, it is generally accepted in Ontario.

What about my BC Power of Attorney? Is it valid here?

While out-of-province Powers of Attorney are technically valid if they complied with the law where they were made, Ontario banks and hospitals are notoriously hesitant to accept them. It is highly recommended to draft new Ontario Powers of Attorney.
