The most common estate planning mistakes include failing to create a will, not updating documents after major life changes, and overlooking powers of attorney. In many cases, families also misunderstand how probate works in Ontario; those gaps can lead to delays, disputes, or unintended outcomes. Getting proper legal guidance early usually makes all the difference.

Fast Facts

• Roughly 57% of Canadians do not have a current, valid will, according to surveys conducted in recent years
• In Ontario, an estate without a will is distributed according to the Succession Law Reform Act, which may not reflect your wishes at all
• Powers of attorney for property and personal care are separate documents; many families only prepare one, or neither
• Beneficiary designations on registered accounts like RRSPs and TFSAs can override what your will says, which catches a lot of people off guard
• Families in Mississauga, Etobicoke, and Brampton frequently contact wills and estate lawyers Toronto-wide only after a crisis has already started

Why So Many Families Put Estate Planning Off

Talking about death and incapacity is uncomfortable. That’s probably the most honest reason estate planning gets delayed, sometimes for years. But from what we’ve seen, the families who wait the longest are often the ones who face the most complicated situations afterward. A parent in Brampton who passes without a will, an aging spouse in Etobicoke who can no longer manage finances without a power of attorney in place; these situations create real legal and emotional strain. The paperwork feels abstract until it suddenly isn’t, and by then, options are limited.

Mistake 1: Not Having a Will at All

This is the most straightforward mistake, and also the most common. No will means no control. Assets are divided by the province using a formula that doesn’t account for your relationships, your intentions, or your family’s specific needs. Common-law partners are particularly vulnerable here, since Ontario’s intestacy rules don’t treat them the same as married spouses. A basic will isn’t expensive to prepare. But the cost of dying without one, in legal fees, family conflict, and time, can be significant. Worth doing sooner.

Mistake 2: Writing a Will and Never Updating It

A will that was accurate ten years ago may be completely wrong today. Divorce, remarriage, new children or grandchildren, a major asset purchase, a falling out with a named executor; any of these changes can make an old will problematic. In many cases, people assume their will is fine because nothing dramatic has happened. But life changes quietly, bit by bit, and the document doesn’t update itself. It’s generally considered good practice by estate lawyers across Ontario to have a will reviewed every three to five years, or after any significant life event.

Mistake 3: Overlooking Powers of Attorney

Powers of attorney are often treated as an afterthought, even though they’re arguably just as important as a will. Two kinds exist in Ontario: one for property, which covers financial decisions, and one for personal care, which covers health and living decisions. Both are needed. Neither is automatically covered by the other. A family in Mississauga once contacted our office after their elderly mother had a stroke, only to discover no power of attorney had been put in place. Legal authority to help her took months to be established. That delay was painful and, I suppose, entirely avoidable.

Mistake 4: Ignoring Beneficiary Designations

Registered accounts like RRSPs, RRIFs, and TFSAs allow a beneficiary to be named directly. That designation passes outside of your will entirely. So if your will says one thing and your RRSP says another, the account wins. This catches families off guard more often than you’d expect. An ex-spouse listed as beneficiary on a registered account can legally receive those funds even if a newer will exists. Beneficiary designations should be reviewed regularly, especially after major life changes; it’s a step that’s easy to skip and costly to miss. Anyway, that’s usually where it clicks for people.

Mistake 5: Choosing the Wrong Executor

Naming an executor is a decision that deserves real thought. The executor is responsible for managing the estate, filing taxes, communicating with beneficiaries, and navigating probate if required. It’s a significant role, and not everyone named is actually suited for it. Sometimes a well-meaning family member is chosen out of habit or loyalty, but lacks the organizational capacity or emotional distance to handle the job well. In other cases, the named executor has predeceased the testator, and no alternate was listed. Both situations create complications. The best executor is someone organized, trustworthy, and ideally willing to seek legal guidance when it’s needed.

Mistake 6: Misunderstanding How Probate Works in Ontario

Probate is the court process through which a will’s validity is confirmed and the executor is given formal legal authority. Not every estate requires it, but many do, particularly when real property is involved or financial institutions request it. In Ontario, an Estate Administration Tax is applied during probate, sometimes called a probate fee, and it’s calculated as a percentage of the estate’s value. Families are often surprised by this cost. Understanding what probate involves, and planning for it, is part of what a wills and estate lawyer helps with; it’s not something to be figured out after the fact.

Mistake 7: Trying to Do It Without Legal Guidance

Online will kits and template documents are widely available. And while they might seem like a practical shortcut, they carry real risk. A will that isn’t properly signed and witnessed in Ontario can be found invalid. A trust that isn’t structured correctly may not achieve what was intended. Powers of attorney that use vague language can create disputes. The legal requirements around estate documents are specific, and the consequences of getting them wrong tend to fall on the people who were meant to be protected. Working with a qualified wills and estate lawyer in the Greater Toronto Area is, in most cases, the most reliable path forward.

Mini-FAQ

Q: What happens if someone dies without a will in Ontario?

When a person dies without a will, their estate is considered intestate. A fixed formula is then applied by the province to distribute assets, regardless of what the deceased may have wanted. Close friends, common-law partners of shorter duration, and certain family members may receive nothing. Not a comfortable situation for anyone left behind. That still surprises people.

Q: Is estate planning the same as probate?

Fair point to raise, because these two things are often confused. Estate planning is what happens while you’re still alive, with wills, trusts, and powers of attorney being prepared for the future. Probate, on the other hand, is a court process that validates a will after death and gives the executor legal authority to act. Different stages, different professionals involved. A wills and estate lawyer can help with both, though the timing and purpose are quite distinct.

Q: Do I really need to update my will after remarrying?

Look, this is one of the most commonly skipped steps we see. In Ontario, an existing will isn’t automatically revoked by marriage the way it once was under older legislation, but the dynamics of blended families create real complications if documents aren’t reviewed. An outdated will can unintentionally exclude a new spouse or leave stepchildren in a difficult position. Worth revisiting sooner rather than later.

Q: What is a power of attorney and why does it matter?

A power of attorney is a legal document that gives someone you trust the authority to make decisions on your behalf, either for finances or for personal care and health. Both are needed. Many families assume one document covers everything, which it doesn’t. If you become incapacitated without these in place, a court application may be required just to manage your own affairs. Avoidable, with the right preparation.
