CPAs in Canada are bound by a professional code of conduct written and enforced by their provincial body, and they must also log ethics learning: CPABC and CPA Alberta both require four hours of verifiable ethics CPD over a rolling three-year period. Those are the ethics requirements you can point to if you ever doubt your accountant.
What does the CPA code of conduct ask for?
Each province publishes its own code. CPA Ontario’s came into effect on 26 February 2016, and the codes we looked at are built around the same handful of principles: professional behaviour, integrity and due care, objectivity, professional competence and confidentiality.
In plain terms, your accountant shouldn’t mislead you, shouldn’t let a conflict of interest bend their advice, must be competent for the work they take on, and must keep your information private unless they have proper authority to share it. Wording and detail differ by province, and we couldn’t read every code in full, so read the one for your province if a dispute is serious.
How many ethics hours must a CPA complete?
| Body | Ethics requirement | Period |
|---|---|---|
| CPABC | 4 hours of verifiable ethics CPD | Rolling three calendar years |
| CPA Alberta | 4 hours of verifiable ethics within 120 hours of total CPD | Three-year rolling cycle |
| Other provinces | Check the provincial body | Not confirmed here |
CPABC says the learning has to go beyond knowing the rules. It has to deal with applying ethical principles to the member’s own work, so reading a bulletin about a bylaw change doesn’t meet it on its own. Topics it lists include independence and conflicts of interest, ethical decision making and anti-money-laundering.
Four hours over three years isn’t much, and you can argue about whether it’s enough. But it’s a real, checkable requirement.
Why do ethics rules matter to your tax bill?
Here’s where it gets practical. Suppose you earn $85,000 in Ontario. Your income tax is about $15,551. Now imagine a preparer who adds a $5,000 deduction you can’t support. On our numbers that would cut your tax by $1,482.50, which is the marginal rate at your income of about 29.65% applied to the extra deduction.
That’s the temptation, and it’s why a good accountant says no. The saving isn’t yours to keep if the CRA later refuses the claim. Try it yourself in the income tax calculator, and use the tax refund calculator to see whether a promised refund is believable.
If a promised refund looks too big for your income, ask where it comes from.
What if you think your CPA crossed a line?
Go to the provincial body. CPA Alberta says it has a conduct and discipline section and handles questions about a registrant’s history in writing. Other provinces have similar processes, but we haven’t confirmed the steps for each, so look for “complaints” or “conduct” on the body’s website.
Before you file one, write down what happened and when. Keep the engagement letter, your emails and the returns. Confidentiality works in your favour here, since your accountant can’t casually discuss your affairs with others, but it doesn’t stop you from sharing your own file with the regulator.
Mistakes and limits
Ethics rules don’t set prices or promise results. They also don’t cover people who aren’t CPAs, because the CPA codes apply to CPA members and firms. If you’re unsure, run your credits through the tax credits calculator and ask your preparer to explain any gap. It covers federal credits only.
And note what we haven’t verified: the ethics CPD hours in provinces other than Alberta and British Columbia, and the current complaint steps in each province.
Where the numbers come from
The ethics hours come from the CPABC and CPA Alberta CPD pages. The principles and the 2016 date come from CPA Ontario’s published code. Tax examples use 2026 federal and Ontario rates from the CRA. We aren’t connected with any CPA body or government.
Frequently asked questions
How many ethics hours must CPAs do?
CPABC requires 4 hours of verifiable ethics CPD in a rolling three-year period. CPA Alberta requires 4 hours within 120 hours of CPD over three years. We didn't confirm the other provinces.
What principles does the CPA code cover?
Professional behaviour, integrity and due care, objectivity, professional competence and confidentiality, as published in CPA Ontario's code.
Does the code cover tax preparers who aren't CPAs?
No. The CPA codes apply to CPA members and firms. A preparer without the designation isn't covered by them.
Who do I complain to about a CPA?
The provincial CPA body where they're registered. CPA Alberta describes a conduct and discipline section and written inquiries about a registrant's history.
Can an accountant share my tax details with anyone?
The code treats confidentiality as a duty, so they need proper cause and authority. Read your province's code for the exceptions.
