Windfall or Inheritance in Canada

By Shea Sanche, CFP® · Last reviewed: April 2026

The First Rule: Slow Down

The most important thing you can do after receiving a windfall is nothing. Resist every pressure - internal and external - to make immediate decisions. The financial decisions you make in the first 90 days after a windfall are the ones most likely to be regretted. Give yourself time.

Understand the Tax Picture First

In Canada, inheritances are generally not taxable to the recipient - but the estate paid tax on the deceased's final return before you received anything. If you inherit assets rather than cash (a cottage, a portfolio of stocks), the adjusted cost base matters for any future disposition. Get professional tax advice before making any transfers or sales.

The Prioritization Framework

Before making any investment decisions, work through this sequence: address any high-interest debt; fully fund your emergency reserve (3-6 months of expenses); maximize TFSA contribution room; review and update your Will and Powers of Attorney to reflect the new reality; and only then begin the investment discussion.

Common Mistakes That Are Hard to Reverse

Making large gifts to family members before understanding the tax implications; making major lifestyle purchases (a property, a boat) before a plan is established; investing too quickly based on enthusiasm; and failing to update estate documents are the four most common - and most costly - windfall mistakes.

The Psychological Dimension

Inheritances often carry grief, guilt, and obligation. The desire to 'honour' the person who left you the money can lead to emotionally driven financial decisions. A structured planning process - separate from the emotional processing - protects you from making permanent financial decisions during a temporary emotional state.

Common Questions

Answers to the questions people actually ask.

Do I still need a will in Canada if assets are joint?

Yes. Joint ownership can simplify transfers, but it can also create fairness, control, and tax issues. A will plus clean ownership and beneficiary structure protects intent.

What is probate in Canada?

Probate is the legal process that validates a will and allows an executor to distribute assets. Avoiding probate should not create worse tax or family outcomes.

What does an executor do?

An executor administers the estate: collects assets, pays debts and taxes, files returns, and distributes the remainder according to the will. Preparation reduces delays. ← Back to all articles
