Turning $20,000 into $100,000 by 2030 sounds like the sort of goal normally followed by a rocket emoji and an expensive lesson. Yet it isn’t mathematically impossible. It simply requires more than choosing a stock, staring at it encouragingly, and waiting for five bags of money to appear.
Today, let’s look at how investors can get started and one stock to get you there.
Start with the room
The 2026 Tax-Free Savings Account (TFSA) dollar limit is $7,000, so contributing $20,000 today requires unused room from earlier years. Unused room carries forward, while withdrawals generally return as new room the following calendar year. Investors should check their own records before contributing because the CRA’s online total may not yet include recent transactions.
Once money is inside a TFSA, interest, dividends, and capital gains are generally tax-free. Withdrawals also don’t affect federal income-tested benefits such as Old Age Security (OAS). That protection makes a TFSA a wonderful compounding machine, although it still requires something worthwhile to compound.
The math needs help
An untouched $20,000 would need to earn approximately 44.3% annually from August 2026 through December 2030 to reach $100,000. That isn’t a sensible base-case forecast. It’s the investing equivalent of planning every commute around green lights.
Contributions make the target less dramatic. Adding $7,000 at the beginning of each year from 2027 through 2030 would bring total contributions to $48,000. The portfolio would then require an annualized return of roughly 23.8% to reach $100,000. Future TFSA limits may change, and every contribution still requires available room.
Growth needs a business
A 23.8% return remains ambitious, so a savings account won’t be doing the heavy lifting. One candidate for the growth portion is Shopify (TSX:SHOP), the Canadian commerce platform that helps businesses sell online, in stores, through social media, and increasingly through artificial intelligence (AI) assistants.
Shopify stock earns subscription revenue and takes a share of the payments and services flowing through its platform. AI shopping could therefore expand its opportunity rather than replace it. Connecting merchants with customers using AI tools can produce more orders, which gives Shopify stock more chances to collect revenue without opening a single warehouse.
Growth already arrived
Second-quarter revenue climbed 34%, while free cash flow reached an 18% margin. Management expects revenue to grow in the low-30% range again during the third quarter. That combination of rapid sales growth and expanding cash generation gives Shopify stock a more convincing path than a tiny speculative stock hoping to become useful sometime after lunch.
Quality isn’t hiding in the bargain bin. At writing, Shopify stock trades near 103 times trailing earnings. Slower consumer spending, rising AI infrastructure costs, or stronger competition could quickly compress that valuation. A wonderful company bought at a heroic price can still produce painfully ordinary returns.
Bottom line
I wouldn’t place an entire TFSA into Shopify stock merely because a spreadsheet wants $100,000. Investors could make it one higher-growth holding among diversified Canadian growth stocks, add gradually, and keep contributing regardless of the market’s mood.
The account may not reach exactly $100,000 by exactly 2030, and no return is guaranteed. Continued contributions combined with Shopify stock’s expanding AI-commerce opportunity could still move a $20,000 TFSA considerably closer, while giving the compounding process time to finish the job after the calendar stops cooperating.
