How is a non-registered investment account taxed in Canada?
A non-registered account has no contribution limit and no tax shelter. You invest after-tax dollars and pay tax along the way: interest is taxed most heavily, eligible dividends receive a credit, and capital gains are taxed on only part of the gain when you sell. Capital losses can offset gains, and tracking your adjusted cost base keeps the paperwork honest.
It is a good problem to have, and I mean that. You have filled your TFSA, you have used your RRSP room, and you still have money you want to put to work. Then comes the question I hear all the time: now what? That is where a non-registered account comes in. It is less glamorous than the TFSA and it does not come with a tax refund like the RRSP, but it quietly does a lot of heavy lifting once the registered room is gone.
What a non-registered account actually is
A non-registered account is simply an investment account that is not registered with the government the way a TFSA, RRSP, RESP, or RDSP is. There is no contribution limit, no annual room to track, and no special shelter around it. You invest with after-tax dollars, money you have already paid tax on, and you pay tax along the way as your investments earn income or grow.
That also brings freedom. You can put in as much as you want, take it out whenever you want, and use it for any goal. Think of it as the overflow account: registered accounts are the first buckets to fill, this one is what you use when they are full.

How tax works: three kinds of income, three different treatments
This surprises most people. Not all investment income is taxed the same way, and the difference can shape what you choose to hold.
Interest is the simplest and least favourably taxed. Interest from GICs, bonds, and savings accounts is fully taxed as income every year at your marginal tax rate, even if you leave the money in the account.
Eligible Canadian dividends get better treatment through the dividend tax credit system. The corporation has already paid some tax on its profits, so you get a measure of credit when the dividend reaches you. A dollar of eligible Canadian dividends is generally taxed more lightly than a dollar of interest.
Capital gains are generally the most favourably taxed. A capital gain happens when you sell for more than you paid. Only part of a capital gain is taxed as income, check the current inclusion rate, because that rate has been politically debated and it can change. You also usually control the timing, since the gain is only realized when you sell.
Capital losses are not all bad news
Nobody likes watching an investment drop, but a loss can still do useful work. If you sell for less than you paid, that capital loss can offset capital gains.
Losses can be carried back three years to offset gains you already reported, or carried forward indefinitely to offset future gains. Follow the rules carefully, including the rules around buying the same investment back too quickly. Never go looking for losses, but if one happens, it can count for something.
The paperwork nobody warns you about: your adjusted cost base
The key responsibility here is record keeping, and the key number is your adjusted cost base, or ACB. It is basically what your investment cost you, adjusted for additional purchases and reinvested distributions. When you sell, your gain or loss is the difference between what you sold for and your ACB.
Hear this clearly: institutions do not always get your ACB right, especially with reinvested distributions or when you hold the same investment in more than one place. If your ACB is too low, you could pay tax on more gain than you actually made. Keep your confirmations and statements, and track reinvested distributions as they happen. A simple spreadsheet updated once or twice a year serves most people well.
What you hold where, and who this account fits
Does it matter what you hold in each account? At a high level, yes. Interest, dividends, and capital gains are taxed differently outside a registered account, while TFSA income is not taxed at all and RRSP withdrawals are fully taxed as income. That is why asset location matters alongside asset allocation. Allocation is what you own, location is where you hold it. The right answer depends on your income, province, and goals, but small tax efficiencies repeated year after year can add up.
Who does this fit? People who have maximized registered room and are still saving. Business owners investing personally after paying themselves from their corporation. Anyone saving for a goal registered accounts do not fit, from helping adult kids to building a bridge to an earlier retirement. There is no room to lose, no deadline, and no penalty for taking money out when life changes.
If your TFSA and RRSP are full, do not see this account as an afterthought. It is a flexible, powerful next step that rewards a bit of knowledge and organization. Get clear on how the three kinds of income are taxed, track your ACB, and think about what belongs where, and you are already ahead of most people.
