A single $7,000 Tax-Free Savings Account (TFSA) contribution growing at 8% annually could become roughly $70,400 after 30 years. No heroic market timing. No mysterious crypto wallet. Just a very patient dollar learning to multiply.
The TFSA makes that compounding especially powerful because interest, dividends, and capital gains generally remain tax-free. Withdrawals also won’t increase taxable income or reduce federal income-tested benefits, giving investors considerably more control over their future cash flow.
The 2026 contribution limit is $7,000. Someone eligible every year since 2009 who has never contributed could have $109,000 of accumulated room, although younger Canadians, new residents, and existing contributors will have different amounts. Unused room carries forward, while withdrawals return as new room the following calendar year.
Those benefits make investing inside a TFSA ideal for buy-and-hold stocks. Losses can’t be claimed against taxable gains, however, so this isn’t the account for tossing darts at speculative companies and hoping one develops artificial intelligence (AI) by Thursday. That said, which companies should be held long term?

SHOP
Shopify (TSX: SHOP) provides the portfolio’s growth engine. Its platform helps businesses sell online, in stores, and through social media while supplying payments, financing, shipping, and other commerce tools.
First-quarter revenue grew 34%, while the free-cash-flow margin reached 15%. Shopify stock is also positioning its enormous merchant network for agentic commerce, where AI assistants can discover products and complete purchases for shoppers.
The opportunity comes with an enthusiastic price tag. Shopify stock trades around 66 times forecast earnings, leaving little room for disappointing growth. Competition, tariffs, weaker consumer spending, or poorly executed AI investments could hurt, making gradual purchases far more sensible than one grand entrance.
CNR
Canadian National Railway (TSX: CNR) adds something Shopify stock can’t provide: thousands of kilometres of track that a new competitor can’t easily recreate.
CNR stock transports grain, energy products, vehicles, consumer goods, and industrial materials across a network connecting three coasts. First-quarter revenue ton miles rose 3% to a company record, while free cash flow jumped 44% to $900 million as network speed and efficiency improved.
The shares trade near 24 times trailing earnings, which looks fair rather than cheap. A recession, trade disruption, accidents, or rising costs could weaken results, yet CNR stock’s irreplaceable network and pricing power make it one of the sturdier Canadian stocks to buy for several decades.
RY
Royal Bank of Canada (TSX: RY) supplies the financial ballast. It earns through Canadian banking, wealth management, insurance, capital markets, and operations in the United States, reducing its dependence on any single revenue source.
Second-quarter net income climbed 25% year over year to $5.5 billion. RBC stock’s 13.5% common-equity tier-one ratio also provides a substantial capital buffer, supporting lending, dividend increases, and share repurchases.
At roughly 19 times trailing earnings, RBC stock carries a premium valuation. Rising loan losses, a housing downturn, or weaker capital markets could slow growth, so even Canada’s largest bank shouldn’t occupy the entire TFSA.
Bottom line
These stocks won’t rise neatly every year, because apparently markets enjoy some drama, though investors may not. Regular contributions, reinvested returns, and decades of patience can nevertheless allow their businesses to compound while every dollar of future TFSA growth remains available for the investor who waited.
