I sat across a pharmacist last year. Sharp. Successful. Making well over $150,000 annually. She had a financial advisor, an accountant, and a full benefits package. But, she had never heard of tax-efficient investing. Not even the term. Her entire TFSA was holding a GIC earning 3.5%. Her RRSP held a growth ETF that she has been building for six years. She had it all backwards, and no one told her. Here's what tax-efficient investing means: Every account you hold in Canada has a different tax treatment. Your TFSA shelters growth permanently. Your RRSP defers tax. Your non-registered account taxes dividends, interest, and gains differently. The asset you put inside each account should be based on how that account is taxed. For example, Growth assets (highest potential gains) belong in the TFSA. Interest-generating assets belong in the RRSP. Canadian dividend-paying stocks usually work well in non-registered accounts because of the dividend tax credit. In summary, in Canada, when you put assets in the right account, you keep more of what you earn. For the Pharmacist? A single restructuring conversation could have changed her after-tax retirement income. ย Curios, what account structure are you currently using and have you ever reviewed whether it's the right fit for where you are now?
