Year-End 2026 Estate Planning Checklist: 9 Steps Ontario Residents Over 55 Must Complete Before December 31

Why December 31 — Not March 1 — Is the Deadline That Matters

Most Canadians think of March as tax season. The RRSP contribution deadline for the 2026 tax year is March 1, 2027, and that date dominates financial planning conversations every winter. But for estate planning, December 31 is the deadline that matters. Capital gains and losses, charitable donations, beneficiary designation changes, and most legal documents all operate on the calendar year. Miss December 31 and you wait 365 days for the next opportunity — or, if you die in the interim, the opportunity is gone permanently.

This checklist is built for Ontario residents over 55 who own property, hold registered accounts, and have family members who will eventually inherit their estate. Each of the nine steps has a specific action, a specific deadline, and a specific consequence for inaction.

Step 1: Review Beneficiary Designations on RRSPs, TFSAs, and Life Insurance

Beneficiary designations override your will. This is not a suggestion or a guideline — it is the law in Ontario under the Succession Law Reform Act. If your RRSP names your ex-spouse from a marriage that ended in 2015, that ex-spouse receives the RRSP proceeds when you die, regardless of what your will says. Your executor cannot redirect the funds. Your current spouse cannot claim them. The designation on the account wins.

Before December 31, confirm the beneficiary on every registered account and every life insurance policy:

• RRSPs and RRIFs: Name your spouse as beneficiary for the tax-free rollover under ITA 60(l). If you name your estate instead, the RRSP value is included in your terminal return as income and also passes through probate — double cost
• TFSAs: Name your spouse as successor holder (not just beneficiary) to preserve the tax-free status of the account. A beneficiary receives the value; a successor holder receives the account itself
• Life insurance: Confirm the beneficiary is current. A $500,000 policy naming a deceased parent creates a legal and administrative nightmare for the estate. For more on how insurance and registered accounts are treated differently at death, see our life insurance vs. inherited RRSP comparison
• Pension plans: Employer pensions, DBRS, and DCRS often have their own beneficiary designation forms separate from personal accounts — check with your plan administrator

Step 2: Harvest Capital Losses Before December 31

If your non-registered investment portfolio holds positions with unrealized losses, selling them before December 31 creates capital losses that can offset gains — both current-year gains and, critically, gains triggered by the deemed disposition at death.

Here is why this matters for estate planning specifically: under ITA 111(2), in the year of death and the immediately preceding year, net capital losses carried forward from prior years can be applied against any income — not just capital gains. A $50,000 capital loss harvested in 2026 that sits unused can offset $50,000 of RRSP/RRIF income, pension income, or employment income on your terminal T1 return if you die in 2027 or later. No other year gives capital losses this flexibility.

The 2026 inclusion rate and the $250,000 threshold

The capital gains inclusion rate for 2026 is 50% on the first $250,000 of net capital gains and 66.67% on amounts above that threshold. Loss harvesting that reduces your net gain below $250,000 saves an extra 8.33 cents per dollar of gain — the difference between the two inclusion tiers. On a $400,000 deemed disposition at death, harvesting $150,000 in losses reduces the net gain to $250,000, keeping everything in the lower tier and saving approximately $12,500 in additional tax.

Step 3: Update Your Power of Attorney for Property

The power of attorney for property is the document Ontario executors and families most frequently discover is missing or outdated. Unlike a will — which takes effect at death — the POA for property governs your finances during incapacity. Without one, no family member has legal authority to access your bank accounts, manage your investments, sell property, or pay your bills.

The alternative is a guardianship application to the Ontario Superior Court under the Substitute Decisions Act: $5,000 to $15,000 in legal fees, 3 to 6 months of delay, and ongoing court oversight of every financial decision. During that gap, bills go unpaid, investment portfolios drift, and time-sensitive decisions — like selling a business or responding to a tax assessment — cannot be made.

Before December 31, confirm:

• You have a signed, witnessed POA for property (not just for personal care)
• The named attorney is alive, willing, capable, and geographically accessible
• The document reflects your current financial situation — an old POA that does not reference a corporation, a rental property, or a brokerage account may create gaps
• You have considered naming an alternate attorney in case the primary is unavailable

Step 4: Review the Principal Residence Exemption Strategy

If you own both a primary home and a cottage (or any second property that qualifies as a principal residence), you must decide how to allocate the principal residence exemption (PRE) years between them. Only one property per family unit can be designated as a principal residence per year.

The optimal allocation depends on which property has the higher per-year gain:

In this example, the Toronto home has the higher per-year gain ($28,571 vs. $25,000), so the PRE should be allocated to the home for the maximum number of years. The cottage gains that are not sheltered by the PRE will be subject to the deemed disposition at death. For Ontario residents, this can trigger tens of thousands in tax on an inherited cottage — see our Ontario cottage deemed disposition guide for the full analysis.

Step 5: Build or Update Your Digital Asset Inventory

Digital assets are the fastest-growing blind spot in estate planning. Your executor needs to know about — and be able to access — every account that holds monetary value or requires action after death.

The inventory should cover four categories:

• Financial accounts: Online banking, brokerage platforms, cryptocurrency wallets (including seed phrases and private keys), PayPal, Interac e-Transfer auto-deposit settings
• Recurring subscriptions: Streaming services, software licenses, domain registrations, cloud storage, and any auto-renewing service the executor must cancel
• Digital property: Websites, blogs, social media accounts with monetization, digital photo libraries, email accounts, and online business assets (Shopify stores, Amazon seller accounts)
• Access method: A password manager with the master password provided to the executor in a sealed envelope stored separately from the will (wills become public through probate — never list passwords in a will)

Step 6: Review Life Insurance Coverage and Beneficiaries

Life insurance is the only asset that creates immediate, tax-free liquidity at death. While the beneficiary designation check in Step 1 covers who receives the proceeds, this step asks a different question: is the coverage amount still appropriate for your estate's needs?

The coverage review should consider:

• Estate tax liability: If the deemed disposition on death will trigger $100,000+ in tax (common for Ontario residents with a home, cottage, and registered accounts), life insurance can provide the cash to pay the tax without forcing a fire sale of assets
• Equalization: If one child inherits the family business and the other receives cash, life insurance can equalize the inheritance without requiring the business child to buy out the other
• Probate fee coverage: Ontario's estate administration tax is 1.5% on estate assets over $50,000. On a $1.5M estate, that is approximately $21,750. Life insurance paid to a named beneficiary bypasses probate entirely
• Term vs. permanent: If you hold a term policy approaching renewal (common for policies purchased in your 40s or 50s), the renewal premium can increase 5x to 10x. Evaluate whether to renew, convert to permanent, or let it lapse based on whether the coverage need still exists

Step 7: Confirm Your Will Reflects Current Tax Rules

If your will was drafted before the 2024 capital gains inclusion rate change — when the $250,000 threshold and the 66.67% rate above it were introduced — the tax assumptions built into your estate plan may be wrong. Wills that direct executors to "minimize tax" or "maximize after-tax value" need to account for the two-tier inclusion rate, the graduated rate estate (GRE) rules, and the current RRSP/RRIF rollover requirements.

Specific items to review with your estate lawyer:

• Does the will include a GRE designation to access graduated rates for up to 36 months after death? See our GRE guide for the full savings calculation
• Does the will direct registered assets (RRSPs, RRIFs) to the surviving spouse personally — not to a trust?
• Are the executor provisions current? Is the named executor willing and able to serve?
• Does the will address the two-tier capital gains inclusion rate in its tax minimization clauses?

Step 8: Make Charitable Donations Before December 31

Charitable donations made before December 31, 2026 generate a tax credit on your 2026 return. For estate planning, strategic charitable giving in the final years of life can significantly reduce the tax burden at death.

Two approaches are particularly powerful:

• Donate publicly traded securities directly: If you donate shares with an unrealized gain directly to a registered charity (not sold first), the capital gain is completely exempt from tax. You receive the donation tax credit based on the full fair market value of the shares, and you pay zero tax on the gain. On a $50,000 donation of shares with a $30,000 ACB, you avoid approximately $5,350 in capital gains tax (on the $20,000 gain at 50% inclusion and 53.53% rate) and receive a donation credit worth approximately $21,500
• Testamentary donation planning: Your will can direct charitable gifts at death, and the donation credit can be claimed on the terminal return or the preceding year's return. But year-end giving during your lifetime lets you see the tax benefit immediately and reduces your estate's overall value for probate purposes

Step 9: Complete the Year-End Action Grid

This is the summary. Print it, check each box, and confirm the completion date. Every item has a December 31, 2026 deadline unless otherwise noted.

The Cost of Waiting: What Happens If You Miss December 31

Estate planning procrastination has a specific dollar cost. If you die in 2027 without completing these steps in 2026:

• Missed capital loss harvesting: Unrealized losses in your portfolio die with you — your estate cannot sell them at a loss. The loss simply disappears. A $50,000 unrealized loss that could have offset estate gains at death is worth approximately $13,000 to $17,000 in tax savings, depending on the inclusion rate tier
• Outdated beneficiary designation: A $200,000 RRSP naming the wrong person redirects $200,000 with no recourse. The executor cannot override the designation
• Missing POA for property: A guardianship application costs $5,000 to $15,000 and takes months. Investment decisions cannot be made during the application period
• Wrong PRE allocation: If the executor claims the exemption on the wrong property, the resulting tax on the cottage or home can exceed $50,000 — and the election, once made on the terminal return, is difficult to amend

The One Action That Ties Everything Together

If you do only one thing from this checklist before December 31, make it Step 1: review every beneficiary designation. It takes two hours. Call your bank, your insurance company, and your employer's pension administrator. Confirm that the named beneficiary on every account matches your current wishes. This single action prevents more estate disputes, unintended tax consequences, and family conflicts than any other step on the list.

For the other eight steps, schedule a meeting with your estate lawyer, your accountant, and your financial advisor before mid-November — December appointments fill quickly, and some of these actions (capital loss harvesting, charitable donations of securities) require processing time that firms cannot guarantee if you wait until the last week of the year.

For Ontario residents with estates in the $1M to $3M range, the intersection of estate planning and tax-year deadlines creates both risk and opportunity. Our inheritance financial planning team works with families across the GTA to coordinate these year-end actions with the broader estate plan — ensuring that the December 31 deadline works for your estate, not against it.
