In Ontario, law firms typically offer flat-fee packages for married couples seeking Mirror Wills, ranging from $1,000 to $2,500 CAD. This package usually includes two reciprocal Wills and Powers of Attorney. However, if you own a private corporation or blended family assets, complex planning will trigger hourly billing at $300 to $500 per hour.
When married or common-law couples in Ontario sit down to plan their estates, their wishes are usually identical. Whether they live in a suburban home in Mississauga, a condo in London, or a rural property near Kingston, the instruction is almost always: “If I die, leave everything to my spouse. If we both die, leave everything equally to our children.”
To achieve this, Ontario estate lawyers use “Mirror Wills.” 📍 Mirror Wills are two separate legal documents-one for each spouse-that contain virtually identical (reciprocal) terms. Because the lawyer is drafting the same core structure twice, law firms typically bundle them into a cost-effective flat-fee package. However, not every couple qualifies for a simple package. This guide explores how Mirror Wills work, what is included in standard legal packages, and when complex assets require a more expensive, custom-tailored approach.
Step-by-Step Process for Mirror Wills in Ontario
Drafting Mirror Wills is a highly streamlined process for standard estates. Because both spouses must agree on the distribution of their assets, the law firm will represent you jointly.
Step 1: The Estate Intake Questionnaire
Before meeting the lawyer, you will fill out a detailed family questionnaire. 📝 You must list all your major assets (homes, RRSPs, TFSAs, life insurance policies) and liabilities. Crucially, you must inform the lawyer how the assets are owned-for example, if your home is owned as “Joint Tenants,” it automatically passes to the surviving spouse outside of the Will.
Step 2: The Joint Legal Consultation
Both spouses will meet with the lawyer together. The lawyer will explain the implications of a joint retainer. If a conflict of interest arises later (for example, if one spouse secretly asks to change their Will to exclude the other), the lawyer must withdraw from representing both of you. During this meeting, you will confirm your primary beneficiaries and backup beneficiaries.
Step 3: Choosing Estate Trustees and Guardians
You must select an Estate Trustee (Executor). Usually, spouses name each other as the primary executor. You must also name a backup executor (like a trusted sibling or adult child) in case you pass away together. 👪 If you have minor children, you will legally appoint a Guardian who will take physical custody of your kids if both parents die.
Step 4: Drafting and Legal Review
The law firm will draft the two Mirror Wills, along with Continuing Powers of Attorney for Property and Powers of Attorney for Personal Care (medical decisions). You will review the drafts at home to ensure all names are spelled correctly and the financial percentages align with your wishes.
Step 5: The Signing Ceremony
To be legally valid under Ontario’s Succession Law Reform Act, a Will must be signed in the physical or virtual presence of two adult witnesses who are not beneficiaries. 📣 You will attend a signing ceremony at the law office, where the lawyer will formalize the documents with Affidavits of Execution.
How Much Does it Cost in Ontario?
The beauty of Mirror Wills is the predictability of costs. Because the legal logic is mirrored, the second Will takes the lawyer significantly less time to draft, resulting in a bundled discount.
| Legal Service / Package | Estimated Cost (CAD) | What is Typically Included |
|---|---|---|
| Basic Mirror Wills (No POAs) | $800 – $1,500 | Drafting two identical Wills leaving assets to each other, then to children. |
| Full Estate Package (Wills + POAs) | $1,500 – $2,500 | Two Mirror Wills plus four Powers of Attorney (Property and Personal Care for both spouses). |
| Blended Family Trust Add-on | $2,500 – $4,000+ | If you have children from a previous marriage, standard Mirror Wills are dangerous; custom spousal trusts are required. |
| Corporate Will (Dual Wills) | $3,000 – $6,000+ | If you own a private Ontario corporation, the lawyer will draft a Primary and Secondary Will to avoid massive probate taxes. |
Be aware that if you need complex tax planning, Henson Trusts for disabled children, or corporate restructuring, lawyers will abandon the flat-fee package and bill you at their hourly rate (typically $300 to $500 per hour). 💵
How Long Does the Process Take?
For a standard family with no corporate assets, the Mirror Will process is highly efficient and rarely takes more than a month.
- Initial Consultation to Drafts: After meeting with your lawyer, expect to receive the first drafts of your documents via email within 2 to 3 weeks.
- Review and Revisions: Minor changes, such as updating an executor’s address, usually take 2 to 4 days to finalize.
- Final Execution: Once approved, the signing ceremony takes about 30 minutes. The entire process from start to finish is usually completed in 3 to 4 weeks.
Frequently Asked Questions (FAQ)
Are Mirror Wills the same thing as a Joint Will?
No. A Joint Will is a single legal document signed by both spouses. Joint Wills are rarely used in Ontario anymore because they are inflexible and difficult to probate. Mirror Wills are two completely separate, individual legal documents that simply happen to contain the same instructions.
Can the surviving spouse change their Will later?
Yes. Because they are individual documents, the surviving spouse has the legal right to rip up their Mirror Will and write a new one after you die. If you want to legally lock your spouse from changing their Will (e.g., to ensure they don’t leave your money to a new partner), you need a contract called a “Mutual Will Agreement.”
What happens if we get divorced?
Under recent updates to Ontario law, if you get formally divorced, the clauses in your Will that leave gifts to your ex-spouse, or appoint them as an executor, are automatically revoked. However, merely separating does not revoke the Will. Always write a new Will immediately upon separation.
Do we have to leave everything equally to our kids?
No, you have testamentary freedom in Ontario. You can leave 80% to one child and 20% to another. However, if you have dependents (like minor children or a disabled spouse) and fail to provide for them adequately, they can sue your estate under the Succession Law Reform Act.
Why are blended families considered “complex”?
If you have a child from a previous marriage and you sign a basic Mirror Will leaving everything to your new spouse, there is no guarantee your biological child will ever get a dime. When you die, your new spouse inherits everything and could rewrite their Will to leave it all to their own children. Complex spousal trusts are required to prevent this.
