A Tax-Free Savings Account (TFSA) can be completely full and still barely be doing its job.
That sounds odd until you remember the âSâ stands for savings, not stocks. Canadians can hold cash inside a TFSA, and plenty do while waiting for interest rates, markets, elections, recessions, or literally anything else. The problem is time.
Suppose $7,000 sits in cash earning 2% for 20 years. It would grow to about $10,400. At an illustrative 8% annual return, the same amount would reach roughly $32,600. Thatâs more than $22,000 of potential difference from one contribution alone.
An 8% stock market return certainly isnât guaranteed. Yet it shows why waiting indefinitely can become an investment decision of its own.
The value of a TFSA
The 2026 TFSA dollar limit is $7,000. Unused contribution room carries forward, so Canadians who havenât always maxed out their accounts may have considerably more available. Withdrawals generally return as contribution room in the following calendar year.
Thereâs another important wrinkle. Investment growth doesnât consume additional room. If $7,000 invested inside a TFSA eventually becomes $20,000, that extra $13,000 hasnât created an over-contribution problem. Itâs simply growth occurring inside a TFSA, generally tax-free.
Cash absolutely belongs there when youâll need the money soon. For money intended to remain untouched for 10 or 20 years, Iâd want a better reason than âIâm waiting for the market to feel safer.â
WCP
Whitecap Resources (TSX: WCP) is one stock Iâd consider putting that long-term TFSA cash to work in. WCP stock produces oil and natural gas across Western Canada. The business became considerably larger after combining with Veren, creating one of Canadaâs biggest oil and gas producers with a broader collection of assets across Alberta, Saskatchewan, and British Columbia.
That deal is now starting to show up where investors want it: cash. Whitecap generated a record $925 million in free cash flow during the second quarter. At the same time, net debt fell to $2.5 billion, equal to only about 0.5 times annualized funds flow. That gives management room to develop its assets, reduce debt, and keep sending cash to shareholders.
Meanwhile, WCP stock currently pays $0.0608 per share every month, or $0.7296 annually. At a recent price around $16.89, that produces a yield of roughly 4.3%. Hereâs what putting a $7,000 TFSA contribution into the shares could look like today.
That works out to roughly $25.17 per month at the current dividend rate. Those payments can be taken as cash, but investors who donât need the income yet can reinvest them into more shares. More shares produce more dividends, which can buy still more shares. Thatâs how Canadian dividend stocks can become increasingly useful when theyâre given enough time.
Foolish takeaway
WCP stock is an energy producer, not a utility. Oil and natural gas prices can move violently, dragging cash flow and the share price with them. The dividend isnât guaranteed, and a prolonged commodity downturn could force management to rethink spending or shareholder returns.
That risk is why I wouldnât put every TFSA dollar into WCP stock. Still, the balance sheet is stronger, the Veren combination is producing cost savings, and the company is generating substantial free cash flow while paying shareholders every month.
Cash can make a TFSA feel safe. Over a decade or two, however, safety from volatility can become exposure to something else: barely growing at all.
For long-term money, Iâd rather give a business like Whitecap time to produce cash, dividends, and potential capital growth than leave that TFSA contribution sitting around waiting for the perfect moment that may never arrive.
