Starting to invest is easier than ever. You can open a brokerage account, transfer money and buy an ETF before you’ve figured out what you’re doing. That convenience can push beginners straight to what should I buy? Which ETF? Which stock? Those are fair questions, but there are several things worth understanding before you press the buy button. Canadian investors also have another layer to consider: registered accounts, tax rules, contribution limits and a domestic market concentrated in a few sectors.
Here are the 10 things I’d understand before getting started.

#10 — Get Your Financial Foundation in Order
What It Means
Investing shouldn’t leave you unable to handle normal life. Before putting every spare dollar into the market, think about emergency savings and expensive debt.
Why It Matters
Markets don’t care when your furnace breaks or your vehicle needs repairs. If an unexpected expense forces you to sell during a downturn, your financial situation has made the decision for you. Paying 20% interest on a credit card while hoping investments earn 7% or 8% is also hard to overcome.
Put It Into Practice
Know what you owe, what interest you’re paying and how much accessible cash you have. I like investing more when the money feels investable.
#9 — Know When You’ll Need the Money
What It Means
Your time horizon should influence how much risk you take. Money for a house next year has a different job than money you’re investing for retirement 25 years from now.
Why It Matters
Markets can fall at inconvenient times. Stocks may make sense over decades, but not for money you absolutely need next summer.
Put It Into Practice
Ask yourself: When might I realistically need this money back? That answer can eliminate a lot of poor choices.
#8 — Your Real Risk Tolerance May Be Lower Than You Think
What It Means
Everyone likes higher returns. The harder question is how you’ll react when earning them requires sitting through a 20% or 30% decline.
Why It Matters
A theoretically perfect portfolio is useless if you abandon it during a serious downturn. Imagine watching $50,000 become $40,000. Would you hold, buy more or sell?
Put It Into Practice
Be realistic about both your financial and emotional ability to handle losses. There’s no prize for taking more risk than you can live with.
#7 — Understand What You Actually Own
What It Means
You don’t need to become an analyst before buying an ETF, but you should understand where its risk and return come from. An ETF isn’t automatically well diversified just because it owns multiple stocks.
Why It Matters
It’s easy to own several funds and assume you’ve diversified when many of them hold the same companies or sectors.
Put It Into Practice
Look underneath the ticker. What does it own? Which countries and sectors? How concentrated is it? If you can’t explain the investment simply, research it more.
#6 — Diversification Is More Than Owning Several Stocks
What It Means
Real diversification spreads exposure across companies, industries, geographies and, where appropriate, asset classes.
Why It Matters
This matters for Canadians because it’s easy to build a portfolio concentrated in familiar TSX sectors such as financials, energy and materials. I own Canadian companies too, but Canada is only one part of the global economy.
Put It Into Practice
Instead of counting holdings, look at what those holdings expose you to. Ten Canadian stocks from three sectors may be less diversified than one broad global ETF.
#5 — Fees Matter More Than They Look
What It Means
Investment costs include more than trading commissions. Funds can have management expense ratios, while brokerages may charge currency-conversion, account or transaction fees.
Why It Matters
Small annual costs matter over decades because money lost to fees also loses the chance to compound. “Commission-free” doesn’t necessarily mean cost-free.
Put It Into Practice
Check the MER, trading costs and account fees. If you’re buying U.S.-listed investments, look at currency-conversion costs too. Know what you’re paying and why.
#4 — The Account You Use Matters
What It Means
In Canada, choosing the investment is only half the decision. You also need to decide where to hold it.
For 2026, the TFSA annual dollar limit is $7,000. The RRSP dollar limit is $33,810, although your personal room depends on income, unused room and other factors. Eligible first-time home buyers can receive $8,000 of FHSA participation room in their first year, with a $40,000 lifetime limit.
Why It Matters
These accounts aren’t interchangeable. TFSA growth and withdrawals are generally tax-free, while deductible RRSP contributions can reduce taxable income and RRSP withdrawals are generally taxable. RESPs can also attract government education grants for eligible beneficiaries.
Put It Into Practice
Before defaulting to a taxable account, understand which registered account best matches what you’re trying to accomplish.
#3 — Contribution Room Is Your Responsibility
What It Means
Registered accounts come with rules, and exceeding your room can cost you. A common TFSA mistake is withdrawing money and recontributing it in the same calendar year without enough unused room. Withdrawals are normally added back the following January 1, not immediately.
Why It Matters
Your brokerage allowing a contribution doesn’t mean CRA rules allow it. Excess TFSA amounts can generally be taxed at 1% per month while the excess remains.
Put It Into Practice
Track contributions yourself, especially across multiple institutions. Avoiding a CRA problem is a good return on a few minutes of record-keeping.
#2 — Expect the Market to Test You
What It Means
Investing doesn’t move neatly upward. Good companies fall, broad markets decline and popular investments go out of favour.
Why It Matters
Many investing mistakes are behavioural. Investors chase rallies, panic after declines, switch strategies repeatedly or wait forever for the “perfect” entry point. The investment can be reasonable while the investor’s behaviour ruins the result.
Put It Into Practice
Decide what would actually cause you to sell before the market gives you a reason to become emotional. I pay much more attention to this now than when I started.
#1 — Have a Plan Before You Place Your First Trade
What It Means
You don’t need a 40-page financial plan. You do need to know what you’re trying to accomplish. How much will you invest? How often? Which accounts will you use? What will you own? When would you change course?
Why It Matters
Without a plan, every headline becomes a potential decision. A hot stock appears and you chase it. Markets fall and you wonder whether you should sell. A basic framework gives you something more reliable to measure decisions against.
Put It Into Practice
Write down your goal, time horizon, contribution schedule, general portfolio structure and reasons you would change the plan. Your thinking will evolve.
The Outsider Take
When I look back at this list, very little of it is about finding the next great stock. That’s intentional. Researching investments matters, and it’s one of the parts of investing I enjoy most. But the longer I spend around markets, the more I think good long-term investing is built on everything surrounding those investments: understanding risk, controlling costs, using the right accounts, staying diversified and managing your behaviour.
Canadian investors have useful tools available to us. TFSAs, RRSPs, FHSAs and RESPs can all play valuable roles when they’re used for the right purpose, but none of them can replace a sound process. Reasonable investors could rank these points differently. Your goals, timeline and experience will change which ones matter most. Understand what you’re trying to accomplish. Understand what you own. Understand what could go wrong. Then build a strategy you can actually stick with. Your first investment matters far less than the investing habits you build after it.
