Updated Checked by the Tax-Services.ca editorial team How we check
If you’re heading to the CRA office in Toronto with a shoebox of receipts, stop. The Toronto Centre Tax Services Office at 25 St. Clair Avenue East doesn’t offer walk-in counter service, according to the CRA’s own page. What works instead is the phone, your CRA account and, for some people, a free volunteer tax clinic.
What is at 25 St. Clair Avenue East?
It’s an address, mainly. The CRA’s office locations page lists Toronto’s office location at 25 St. Clair Avenue East, Toronto ON M4T 1M4, and the mailing address as Suite 100 at the same building, postal code M4T 0A7. Yes, the two postal codes differ. Copy the mailing one if you’re addressing an envelope.
The office page also gives a fax number, 416-360-8908, and names Sudbury as the tax centre attached to it. It says nothing about what the office does for individuals day to day.

Where can you get help in Toronto without an appointment?
Nowhere at the CRA itself, as far as we can find. The agency’s tax help page points to the Community Volunteer Income Tax Program for free clinics, and to online or in-person help for self-employed people and small business owners through its Liaison Officer Initiative.
The CRA pages disagree on income limits for the clinics, so we’ve left the figures out. Read the current rules on the CRA page. Then find a clinic that matches your situation.
What should you do before you phone?
Torontonians have the easiest time zone of anyone, since the CRA’s hours are Eastern and so are yours. Even so, the lines get jammed at the busy times. Picture Leila, a barista in the Annex, who rings at lunch and gets the automated service. Try off-peak if you can, and not in the weeks around tax time. Have your social insurance number and last notice of assessment ready. Write down the date and the agent’s ID number at the end of the call. If the agent promises something, such as a letter or a corrected assessment, note when it should arrive. That makes a follow-up call far shorter, and it gives you a few words to quote if the answer later changes.
What if you owe money and can’t get through?
Busy lines are a fact of life, and the CRA doesn’t post wait times for these lines, so we won’t guess at them.
Don’t wait for a callback to act. Interest builds on a balance whether the phone is busy or not. Check your amount in your CRA account, and pay from there if you can.
If you’re a self-employed Torontonian, ask yourself if you should be paying in instalments. The tax instalments calculator shows how it works: if you expect $9,000 owing for the year, the equal-payment plan asks for four payments of $2,250. The CRA’s $3,000 threshold applies (it’s lower for Quebec residents, which doesn’t matter in Ontario). The tool offers only the equal-payments method, though the CRA allows other ones.
To see what you might owe or get back, run the income tax calculator with Ontario selected, or the tax refund calculator if you expect money back. Neither replaces the assessment.
How do you spot a fake call claiming to be the CRA?
You can’t always tell by the voice, so don’t try. Hang up and dial 1-800-959-8281 yourself, or sign in to your account and look for the notice. The CRA also lists a fraud and identity theft line, 1-833-995-2336, for Monday to Friday, 6:30 am to 7 pm Eastern.
A caller who tells you to come to the Toronto office should raise a flag, since the agency’s pages say nobody is served at a counter there. That alone makes a demand to show up “at the office” suspicious. We can’t say what every scam looks like, so stick to numbers printed on canada.ca.

Office addresses, the fax number, phone lines and hours come from the Canada Revenue Agency‘s office location, Toronto Centre tax services office, contact and tax help pages, read in October 2026. We aren’t a government service and we don’t speak for one.
