A HISA ETF investor who bought in before the fall of 2023 and checked back a few months later would have found the same fund paying a noticeably lower yield, without ever selling a single unit. Nothing about their own holding changed. The regulator overseeing Canada’s banks did, and the ripple effect touched every HISA ETF in the country at once, which makes this one of the rare Canadian financial products whose fundamental economics were reshaped by a single regulatory decision rather than by market conditions alone.

A HISA ETF, or high-interest savings account exchange-traded fund, is an investment fund that holds cash deposits at Canadian banks, and since early 2024 often a mix of deposits and short-term government treasury bills, structured so its units trade on a stock exchange like any other ETF while aiming to pass along a yield close to what those underlying deposits actually earn. It behaves like a savings account in spirit, cash parked safely with modest, steady growth, but it’s legally and structurally an investment product rather than a deposit, a distinction that matters for both protection and tax treatment.
What a HISA ETF Actually Holds
The fund itself is structured as a trust, pooling investor money and placing the bulk of it as deposits held directly with one or more Canadian banks, with National Bank of Canada identified as the largest single deposit taker for these funds, followed by Scotiabank, CIBC, and BMO. The fund earns interest on those deposits and passes most of it through to unitholders, minus a management fee. Since the regulatory change described below, several HISA ETFs have adjusted their holdings to include Government of Canada treasury bills alongside bank deposits, since both qualify as the kind of highly liquid asset the new rules were built around, which means the exact composition of a specific fund is worth checking rather than assuming it’s purely bank deposits the way it might have been a few years ago.
Why OSFI Changed the Rules in 2024
This is the detail that actually explains why HISA ETF yields moved the way they did, and it’s worth understanding in some depth rather than treating it as background noise. The Office of the Superintendent of Financial Institutions launched a public consultation on HISA ETFs in May 2023, driven by concerns about systemic contagion risk, the potential for regulatory arbitrage, and the fact that these deposits carry none of the guarantees or deposit insurance an ordinary savings account has. OSFI concluded that despite the product’s retail-like appearance to end investors, the deposits themselves are placed directly by large fund managers for reasons that aren’t tied to ordinary day-to-day banking, which meant banks holding this money needed to treat it as a specific category called unsecured wholesale funding, carrying a 100 percent liquidity run-off factor. In plain terms, a bank accepting HISA ETF deposits now has to hold enough highly liquid assets, like government bonds, to cover the full amount if every dollar were withdrawn within 30 days, a much stricter requirement than what applies to typical retail deposits.
What the Rule Change Actually Meant for Yields
Banks facing that stricter liquidity requirement responded by paying less for HISA ETF deposits, since holding extra liquid assets against that funding source costs the bank something. Gross HISA ETF yields sat between 5.3 and 5.5 percent when OSFI announced the change in October 2023, and by the time the new treatment took full effect on January 31, 2024, yields across most major funds had compressed toward the Bank of Canada’s overnight rate at the time. This wasn’t a one-time adjustment tied to a specific fund’s decisions. It applied to every Canadian deposit-taking institution accepting this kind of funding, which is why the effect showed up across the entire HISA ETF category at roughly the same time rather than at just one fund.
The Protection Gap OSFI Itself Pointed To
This is worth stating plainly since it’s easy to assume a HISA ETF works like a regular HISA simply because the name overlaps so heavily. OSFI’s own consultation documents describe HISA ETF units as lacking government guarantees or deposit insurance entirely, a direct acknowledgment from the same regulator that oversees the banks holding the underlying deposits. Mutual funds and ETFs in Canada, HISA ETFs included, aren’t eligible CDIC deposits the way an ordinary savings account is, since owning fund units means owning a claim on the fund’s assets rather than holding a deposit directly. If a CIRO member dealer holding the account became insolvent, protection would flow through the Canadian Investor Protection Fund rather than CDIC, a completely different framework built around dealer insolvency rather than bank failure.
How the Distributions Actually Get Taxed
A HISA ETF’s income gets reported to unitholders on a T3 slip rather than the T5 an ordinary bank account generates, since the fund is structured as a trust rather than a direct deposit relationship, a distinction the Canada Revenue Agency’s own T3 slip guidance draws for any trust-structured fund distributing income to investors. The substance of the tax treatment lands in the same place either way. Interest income distributed by a HISA ETF is fully taxable at the same marginal rate as interest earned directly in a savings account, with no preferential treatment, when held outside a registered account. Holding the ETF inside a TFSA shelters that distributed interest from tax entirely, the same sheltering effect a TFSA-held HISA would provide.
Buying and Selling Works Differently From an Actual HISA
This is a real, practical difference worth knowing before assuming a HISA ETF is a perfect stand-in for a savings account. Since units trade on an exchange, buying or selling involves a brokerage trade that settles over one or two business days, rather than the same-day or next-day access an actual bank transfer from a HISA typically provides. A brokerage commission may also apply depending on the platform used, something an ordinary savings account withdrawal never involves. The fuller comparison between a HISA ETF and an actual savings account is worth reading in full for anyone deciding between the two, since the settlement delay and trading mechanics matter most for money that might be needed on short notice.
Well-Known HISA ETFs Worth Knowing About
Purpose Investments, Evolve ETFs, and CI Global Asset Management all run large, well-established HISA ETFs in Canada, each holding billions of dollars in assets and each affected by the same OSFI rule change described above. Evolve’s own High Interest Savings Account Fund and Purpose’s Renaissance-related fund lineup are worth looking at individually for their specific current holdings and yield, since the exact composition and payout can differ meaningfully between fund managers even though they’re all responding to the same regulatory environment.
What to Actually Check Before Buying One
Confirm the fund’s current yield and holdings composition directly through the fund manager’s own fact sheet, since both shifted meaningfully after the 2024 rule change and continue to move with interest rates generally. Confirm whether the account holding the ETF is inside a TFSA or a non-registered brokerage account, since that decision determines whether the distributed interest is sheltered from tax or fully taxable each year. And before treating a HISA ETF as functionally identical to a savings account, confirm how quickly the specific brokerage settles trades and whether that timeline actually works for money that might need to be accessed on short notice.
Frequently Asked Questions
Did the 2024 OSFI change cause any HISA ETF to actually lose money for investors? No, the change affected the yield these funds could offer going forward, not the value of units already held, and none of the major funds reported a loss of principal tied to the rule change itself.
Can a HISA ETF be held inside an RRSP the same way it can inside a TFSA? Yes, HISA ETFs are eligible investments inside both TFSAs and RRSPs, with the RRSP version deferring tax on the distributed interest until withdrawal rather than sheltering it permanently the way a TFSA does.
Are all HISA ETFs affected equally by the OSFI liquidity rule? Yes, the rule applies to any Canadian deposit-taking institution accepting this type of wholesale funding, regardless of which fund manager’s ETF the deposit originated from, so the underlying pressure on yields applied across the category rather than to specific funds alone.
Does a HISA ETF pay interest daily the way a savings account does? Interest accrues within the fund and gets distributed to unitholders on the schedule set by that specific fund, commonly monthly, rather than accruing directly to the investor’s own account daily the way a bank HISA’s interest does.
