Usually not. A will does nothing while you are alive, so a power of attorney and health-care directive are equally important, and beneficiary designations operate independently of the will entirely.

Do my retirement accounts follow my will?

Typically no — they pass by beneficiary designation. An outdated designation can override your will completely, which is a frequent and painful surprise for families.

What happens if I become incapable without a power of attorney?

Someone must apply to court to be appointed. It is slower, costlier and public, and the person appointed may not be who you would have chosen.

Only for a reason — a minor beneficiary, a beneficiary with a disability, controlling inheritance timing, or holding a business interest. Trusts carry real administrative and tax complexity.

Does my plan still work if I move?

Not necessarily. Validity and procedure are jurisdiction-specific, so review your documents after moving to another province, state or country.

Estate Planning: What You Actually Need

8 min readUpdated January 15, 2026

Most people think estate planning means a will. A will only handles what happens after you die, and only for assets that actually pass under it — which is often less than people assume. Planning for incapacity while you are alive is the part most commonly missing, and the part families feel most acutely.

This guide covers what a complete plan includes and the traps that undo them. It is general information; the rules are jurisdiction-specific, and Quebec follows civil-law procedures distinct from the rest of Canada.

The core documents

A complete plan usually includes a will, a power of attorney for property (a mandate in Quebec), a health-care directive or personal-care appointment, and up-to-date beneficiary designations. If you have minor children, it also names a guardian.

Each does a distinct job. A will is powerless while you are alive; a power of attorney is powerless after you die. Having only one leaves a real gap.

What passes outside your will

Retirement accounts, insurance policies, and some investment accounts typically pass by beneficiary designation. Jointly held property with a right of survivorship passes to the survivor. None of that is controlled by your will.

This is the single most common failure in estate planning: a designation naming an ex-spouse, or made decades ago and never revisited, quietly overriding a carefully drafted will. Review designations whenever you review the will.

Planning for incapacity

You must have capacity to grant a power of attorney, so this has to be done before it is needed. Once capacity is lost, the alternative is a court-appointed guardianship — tutorship or curatorship in Quebec — which is slower, public, more expensive, and may not appoint the person you would have chosen.

Choose separately for finances and personal care, name alternates, and consider safeguards such as accounting requirements. Broad, unmonitored authority over someone's finances is where most elder financial abuse occurs.

Probate, taxes and trusts

Probate validates the will and the executor's authority; whether it is required depends on the assets and jurisdiction, and fees may apply. Estate tax treatment differs substantially — the US has federal estate tax with thresholds that change, while Canada instead generally treats death as a deemed disposition triggering capital gains.

Trusts are worth considering for specific purposes: providing for a minor, supporting a beneficiary with a disability without affecting benefits, controlling timing of inheritances, or holding a business interest. They add cost and complexity, so the purpose should justify them.
