Canada most active stocks and ETFs are the Canadian-listed securities that traded the most shares in a session. Because Canadian trading is split across several exchanges and alternative venues, the list is a useful snapshot of where attention sits, but it says nothing about quality, price direction or suitability. This page covers how to read the list, what is specific to Canadian markets, and how the same trades look to a Canadian resident, a U.S. taxpayer and an NRI or other Indian resident.
What do Canada most active stocks and ETFs show?
The list is built from end-of-day or delayed data and covers stocks and ETFs together; check the name or the fund's description to tell them apart. Canadian listings include a large group of small resource and technology companies on the TSXV next to large TSX issuers, and TMX's own sector profiles name energy, mining, technology, real estate, clean technology and life sciences issuers, plus ETFs and closed-end funds.

How to read it
- Volume versus value. A $1 stock needs far more shares than a $100 stock to move the same dollars, so check price before drawing conclusions.
- Currency. Many securities trade in Canadian dollars, and some in U.S. dollars. Settlement of U.S.-dollar issues has special rules on U.S. holidays.
- Change %. The move against the prior close, which can be large on thin trading.
- Technical rating. A third-party summary of indicators and not a recommendation.

CIPF's stated limits for individuals are generally $1 million for all general accounts combined, such as cash, margin, TFSA and FHSA accounts, plus $1 million for registered retirement accounts and $1 million for RESPs where the client is the subscriber. Claims must be filed within 180 days of the firm's insolvency.
ETFs in Canada
Canadian ETFs generally file a plain-language ETF Facts document, while ETFs listed outside Canada follow the rules of their home country and may not. Foreign-listed ETFs also trade mainly in foreign currencies, may face foreign withholding taxes on distributions and may expose you to foreign estate tax, according to the investor education site GetSmarterAboutMoney.ca. Look at the fund company's own documents before you rely on a ticker.
One list, three readers
| Reader | What changes |
|---|---|
| Canadian resident | Report gains in Canadian dollars. Inside an RRSP or TFSA the account rules apply instead; see RRSP, TFSA, FHSA and RESP explained and retirement and savings accounts compared. |
| U.S. citizen or resident | A Canadian brokerage account counts toward FBAR and Form 8938. Canadian ETFs and mutual funds are usually passive foreign investment companies; see Canadian mutual funds, ETFs and PFIC. |
| NRI or Indian resident | A resident buying Canadian securities uses the Liberalised Remittance Scheme and reports the holding in the Indian return. See LRS explained. |
Tax notes for investors
- Dividends to non-residents. The CRA says the usual Part XIII tax rate is 25% unless a treaty reduces it, and tax correctly withheld is the final Canadian tax on that income. See Part XIII tax for non-residents.
- Gains of non-residents. The CRA links a non-resident's Canadian tax on capital gains to dispositions of certain Canadian property, such as taxable Canadian property, and handles dividends separately through Part XIII withholding. Ask whether a particular holding is covered.
- Reporting. If you are a Canadian resident with large holdings outside Canada, read the T1135 guide.

Frequently asked questions
Are TSX and TSXV volumes combined in one list?
That depends on the data provider. Check whether the list includes all Canadian venues or only primary-exchange trading.
Is the most active list the same as the biggest companies?
No. Market capitalization reflects company size; volume reflects shares changing hands.
Do Canadian ETFs have the same protections as U.S. ETFs?
They sit under Canadian securities rules, with ETF Facts disclosure. Foreign-listed ETFs follow their home jurisdiction. Neither protects against losses from price declines.
Does CIPF cover a fall in my investments' value?
No. CIPF's role is custodial: it helps return property held for you if a member firm becomes insolvent, within limits.
I live in the U.S. and hold Canadian ETFs. Is that a problem?
Often yes, because of PFIC rules and Form 8621. Talk to a CPA before you buy.
