Estate Planning Checklist Ontario 2026: 15 Steps Before It's Too Late

More than half of Canadian adults don't have a will. Among those who do, many have outdated documents, missing powers of attorney, or beneficiary designations that haven't been reviewed in years. In Ontario, the consequences of an incomplete estate plan are severe: your family could face $14,500+ in probate fees on a $1 million estate, months of court delays, and the province deciding who inherits your assets.

This checklist gives you the 15 essential steps to a complete Ontario estate plan in 2026 — organized so you can work through them systematically. Whether you're starting from scratch or reviewing an existing plan, use this as your roadmap.

Step 1: Create or Update Your Will

Your will is the single most important estate planning document. It names your estate trustee (executor), specifies who inherits your assets, and — critically — names guardians for your minor children.

Ontario will requirements:

• You must be 18 years of age or older
• The will must be in writing (typed or handwritten)
• It must be signed by you (the testator) at the end of the document
• It must be witnessed by 2 people who are present at the same time and who are not beneficiaries (or spouses of beneficiaries) under the will

A holograph will — entirely in your own handwriting and signed by you — is valid in Ontario without witnesses, but is more easily challenged in court and is not recommended for complex estates.

Key decisions for your will:

• Estate trustee (executor): Who will administer your estate? Name an alternate in case your first choice can't serve.
• Guardian for minor children: If both parents die, who raises your children? This is arguably the most important clause in a young family's will.
• Asset distribution: Who gets what, in what proportions, and under what conditions?
• Trusts within the will: Should assets for young beneficiaries be held in trust until they reach a certain age?
• Digital assets: Who has access to your cryptocurrency wallets, online accounts, and digital files?

Step 2: Create a Power of Attorney for Property

A Continuing Power of Attorney for Property authorizes someone you trust — called your "attorney" (not a lawyer, just the person you appoint) — to manage your financial affairs if you become mentally incapable. This includes:

• Paying your bills and managing your bank accounts
• Managing your investments and real estate
• Filing your tax returns
• Running or selling your business
• Applying for government benefits on your behalf

Without this document, your family would need to apply to the court for guardianship — a process that typically takes 3 to 6 months and costs $10,000 or more in legal fees. During that time, no one has legal authority to access your accounts or pay your bills.

The word "continuing" is critical: it means the power of attorney remains valid even after you become mentally incapable. A general power of attorney (without the "continuing" designation) terminates when you lose capacity — which is exactly when you need it most.

Step 3: Create a Power of Attorney for Personal Care

A Power of Attorney for Personal Care — governed by Ontario's Health Care Consent Act — authorizes someone to make decisions about your:

• Medical treatment and medication
• Housing and living arrangements
• Nutrition, hygiene, and clothing
• Safety and end-of-life care

This is separate from the Power of Attorney for Property. You need both. You may appoint the same person for both roles or different people — for example, a financially savvy sibling for property and a compassionate family member for personal care.

Consider including a living will or advance care directive within this document. While not a separate legal instrument in Ontario, you can include specific instructions about your wishes regarding life support, resuscitation, and palliative care. These instructions guide your attorney when making difficult medical decisions.

Step 4: Organize and Securely Store Your Documents

Estate documents are useless if no one can find them. Create a comprehensive estate planning binder that includes:

• Original will (store with your lawyer or in a fireproof safe — not a safety deposit box, which can be sealed at death)
• Both Powers of Attorney (originals)
• List of all bank accounts, investment accounts, and insurance policies with account numbers
• Beneficiary designation records for each account
• Location of safety deposit box and key
• Digital asset inventory: email accounts, cryptocurrency wallets (with seed phrases stored separately and securely), online banking, social media accounts
• Business agreements: shareholder agreements, partnership agreements, buy-sell agreements
• Contact information for your lawyer, accountant, financial advisor, and insurance agent

Tell your estate trustee and at least one family member where this binder is located. Consider giving your estate lawyer a copy.

Step 5: Review All Beneficiary Designations

Beneficiary designations on registered accounts override your will. If your RRSP names your ex-spouse as beneficiary but your will leaves everything to your current partner, your ex-spouse gets the RRSP. The designation always wins.

Review and update beneficiary designations on:

• RRSPs and RRIFs — Name your spouse as beneficiary for a tax-free rollover, or name children/others (but the account value will be taxed as income on your final return)
• TFSAs — Name your spouse as successor holder (not just beneficiary) so they inherit the account and keep all contribution room
• FHSAs (First Home Savings Accounts) — Designate a beneficiary to avoid the balance flowing through probate
• Life insurance policies — Name a person, never "my estate." Naming the estate pulls the death benefit into probate.
• Employer pension plans — Ensure your current spouse or desired beneficiary is named
• Non-registered investment accounts — Ask your institution if beneficiary designations (transfer on death) are available

Every account with a named beneficiary (other than "estate") bypasses probate entirely — saving 1.5% of its value in Ontario Estate Administration Tax.

Step 6: Optimize Real Estate Ownership Structure

Real estate is typically the largest asset in an Ontario estate. How it's titled determines whether it goes through probate:

• Joint tenancy with right of survivorship: The property passes automatically to the surviving joint owner — completely outside the will, no probate. This is the standard structure for married couples.
• Tenants in common: Each owner's share forms part of their estate and goes through probate. Used when co-owners want their share to go to different people (e.g., business partners, blended families).
• Sole ownership: The property must go through probate. The full value is included in the probatable estate.

Caution about adding adult children to title: Adding a child as a joint tenant on your property can trigger a deemed disposition for capital gains tax purposes (on non-principal-residence properties), expose the property to the child's creditors or divorce proceedings, and create land transfer tax obligations. Always consult an estate lawyer before changing property ownership.

Step 7: Designate Guardians for Minor Children

If you have children under 18, your will should name a guardian — the person who will raise your children if both parents die. Without this designation, the courts decide, and they may not choose the person you would have wanted.

Consider these factors when choosing a guardian:

• Parenting values and lifestyle alignment
• Financial stability and willingness to serve
• Geographic proximity to your children's school and community
• Age and health of the potential guardian
• Whether to separate guardian duties (person) from trustee duties (money) — you can name different people for each role

Always name an alternate guardian in case your first choice is unable or unwilling to serve. Discuss your wishes with the person before naming them.

Step 8: Address Digital Assets and Online Accounts

Digital assets are an increasingly important — and often overlooked — part of estate planning. Your digital estate may include:

• Cryptocurrency: Bitcoin, Ethereum, and other holdings in wallets or exchanges. Without private keys or seed phrases, these assets can be permanently inaccessible.
• Online financial accounts: Brokerage accounts, PayPal, online banking
• Business assets: Domain names, websites, online stores, intellectual property
• Social media and email: Facebook, Google, Apple accounts (each platform has different legacy/memorial policies)
• Loyalty points and rewards: Aeroplan, credit card points (some are transferable, some expire at death)

Create a digital asset inventory listing all accounts, stored separately from your will (which becomes a public document through probate). Include access instructions or reference a secure password manager. Your Power of Attorney for Property should explicitly grant authority over digital assets.

Step 9: Understand the Deemed Disposition at Death

Canada does not have a traditional inheritance or estate tax. Instead, when you die, the CRA treats you as having sold all your assets at fair market value immediately before death. This is called a "deemed disposition." Any unrealized capital gains are triggered on your final tax return.

In 2026, the capital gains inclusion rate is 50% — meaning half of any capital gain is added to your income and taxed at your marginal rate. For someone in Ontario's top tax bracket (53.53%), the effective tax on capital gains is approximately 26.76%.

Key exceptions and planning opportunities:

• Spousal rollover: Assets transferred to a surviving spouse (or a spousal trust) are transferred at adjusted cost base — no immediate tax. The tax is deferred until the surviving spouse dies or sells the asset.
• Principal residence exemption: Your family home is generally exempt from capital gains tax, even at death.
• Lifetime Capital Gains Exemption (LCGE): In 2026, up to $1.25 million in capital gains on qualified small business corporation shares can be sheltered from tax. This is a major benefit for business owners.
• Charitable donations: Donations made through your will (or by designating a charity as beneficiary on registered accounts) can generate tax credits of up to 33% on amounts over $200, offsetting tax on the final return.

Step 10: Consider a Multiple-Will Strategy

Ontario courts — following the landmark Granovsky Estate v. Ontario (1998) decision — recognize that a person can have two valid wills:

• Primary will: Covers assets that require probate to transfer (real estate, bank accounts, public company shares). This will is submitted for probate and subject to the Estate Administration Tax.
• Secondary will: Covers assets that do not require probate (private company shares, shareholder loans, personal property, art, collectibles). This will is never probated, so no Estate Administration Tax applies to these assets.

For a business owner with $2 million in private company shares, a secondary will can save $30,000 in probate fees alone. This strategy requires an experienced estate lawyer — the two wills must be carefully drafted to avoid one revoking the other.

Step 11: Evaluate Trust Structures

Trusts are powerful estate planning tools that can serve multiple purposes:

• Inter vivos (living) trust: Created during your lifetime. Assets transferred into the trust are no longer in your estate — they bypass probate entirely. Useful for investment portfolios, vacation properties, and business succession.
• Testamentary trust (created in your will): Comes into effect at death. Can hold assets for minor children, spendthrift beneficiaries, or beneficiaries with disabilities. Each testamentary trust is taxed at graduated rates (not the top marginal rate), providing income-splitting benefits.
• Qualified Disability Trust: For beneficiaries eligible for the Disability Tax Credit. Provides ongoing graduated tax rates and protects eligibility for provincial disability benefits.

Important: Transferring appreciated assets into an inter vivos trust triggers a deemed disposition — you may owe capital gains tax at the time of transfer. The 21-year deemed disposition rule also applies to trust-held assets. Work with both a tax professional and an estate lawyer when implementing trust strategies.

Step 12: Plan for Life Insurance as a Tax and Liquidity Tool

Life insurance plays two critical roles in estate planning:

• Tax-free liquidity: The death benefit — paid directly to named beneficiaries — provides immediate cash to cover funeral costs, debts, income tax on the final return, and probate fees. Your family doesn't have to sell assets at a bad time to pay estate taxes.
• Estate equalization: If you're leaving a business or property to one child, life insurance can provide an equivalent value to other children — preventing family conflict.

Life insurance with a named beneficiary (not "the estate") bypasses probate, is protected from estate creditors, and is paid quickly — often within days of the claim. For business owners, corporate-owned life insurance can fund a buy-sell agreement or create a capital dividend account that allows tax-free distributions to shareholders.

Always name a specific person as beneficiary. Naming "my estate" as beneficiary pulls the entire death benefit into the probatable estate — adding up to 1.5% in unnecessary fees.

Step 13: Schedule Regular Reviews

Set a reminder to review your entire estate plan every 3 to 5 years — and immediately after any of these life events:

• Marriage or divorce (marriage revokes your will in Ontario; divorce revokes gifts to your ex-spouse)
• Birth or adoption of a child (update guardian designations and asset distribution)
• Death of a beneficiary, executor, or guardian (update all documents naming that person)
• Significant change in assets (inheritance, sale of business, real estate purchase)
• Move to a different province (estate laws vary significantly between provinces)
• Change in tax law (capital gains rates, RRSP rules, probate fee changes)
• Retirement (triggers new financial structures: RRIF conversions, pension elections, OAS planning)

During each review, check all beneficiary designations, confirm your estate trustee and POA appointees are still appropriate, and update your asset inventory and digital asset list.

Step 14: Communicate Your Plan to Key People

An estate plan that exists only in a filing cabinet helps no one. Make sure the following people know about your plan — and where to find the documents:

• Your estate trustee (executor): They need to know they've been named, where the will is, and have a general understanding of your assets and wishes.
• Your Power of Attorney appointees: Both your property attorney and personal care attorney should have copies of their respective documents and know your wishes — especially regarding medical care.
• Your spouse or partner: They should know the full picture — assets, debts, insurance policies, account locations, and your overall plan.
• Your adult children (if applicable): At minimum, they should know the plan exists and who the executor and POA holders are. Whether you share specific details about asset distribution is a personal decision.
• Your lawyer and financial advisor: They should have copies of key documents and be available to assist your executor.

Step 15: Build Your Professional Team

A comprehensive estate plan involves several professionals working together:

• Estate lawyer: Drafts your will, powers of attorney, and any trust documents. Ensures all documents comply with Ontario law.
• Certified Financial Planner (CFP): Coordinates the financial aspects — beneficiary designations, asset ownership, insurance needs analysis, retirement income planning, and tax projections.
• Accountant (CPA): Handles tax implications of estate structures, final tax return planning, and trust tax filings.
• Insurance advisor: Determines appropriate life insurance coverage for estate liquidity, equalization, and tax funding needs.

These professionals should be communicating with each other. A change to your will may affect your insurance needs. A change to your investment structure may require updated beneficiary designations. Your CFP is often the best person to coordinate across all professionals and ensure nothing falls through the cracks.
