What Is the CRA? Understanding Their Letters and What to Actually Do

A lot of newcomers get their first letter from the Canada Revenue Agency and freeze. The envelope is brown. The letter inside uses words like assessment and reassessment and contribution room. There’s a number at the bottom that might be money you owe — or money you’re getting. It’s hard to tell.

If English is your second language, it’s even harder. The CRA writes in a tone that sounds official and slightly threatening, even when the letter is just saying hello. I’ve translated dozens of these letters for family members over the years. Nine times out of ten, the letter was routine. The panic was the worst part.

So let’s slow down and explain what the CRA actually is, what their letters mean, and how to tell a real one from the scams that target newcomers every single day.

What the CRA Actually Is

The CRA — Canada Revenue Agency — is the federal department that collects taxes and sends out benefits. Think of it like the tax bureau back home, but with two jobs instead of one. They take money in (income tax, GST/HST, payroll taxes) and they send money out (Canada Child Benefit, GST credit, climate rebates, refunds).

That second part is important. Many newcomers assume the CRA only takes. They don’t realize that filing taxes — even with zero income in your first year — is often how you get money. The GST credit, the Canada Child Benefit, the climate action incentive — none of them show up unless you file a tax return. Skip the return and you skip the money.

So the CRA isn’t your enemy. They’re the gatekeeper for both directions of money between you and the government.

The Letters You’ll Actually Get

Most CRA mail falls into a few categories. Once you know the names, the panic drops by half.

Notice of Assessment (NOA)

This is the most common one. After you file your tax return, the CRA processes it and sends back a summary. It shows what they think you earned, what tax you owed, what you already paid, and whether you’re getting a refund or owe more.

Almost everyone gets a Notice of Assessment every year. It’s not a problem — it’s a receipt. Look at the bottom line: refund, balance owing, or zero. That’s the number that matters.

Notice of Reassessment

This one means the CRA went back and changed something on a return you already filed. Maybe an employer sent in a corrected T4. Maybe they disallowed a deduction you claimed. The letter will explain what changed and the new amount.

If you disagree, you have the right to object — usually within 90 days. Don’t ignore it.

Benefit Notices

If you qualify for the Canada Child Benefit, GST/HST credit, or other benefits, the CRA sends a letter explaining how much you’ll receive and when. These are good letters. Save them — you may need them later when applying for daycare subsidies, housing programs, or immigration paperwork.

Review and Verification Requests

Sometimes the CRA wants proof of something you claimed — donation receipts, childcare expenses, medical bills. They’ll ask you to send documents. This is not an audit. It’s just a check.

Send what they ask for, by the deadline, through the upload tool in My Account if you can. Keep copies of everything.

Collections Letters

These show up if you owe money and haven’t paid. They escalate over time — first reminders, then warnings, then more serious action. Interest builds daily on any unpaid balance, so the longer you wait, the worse it gets.

If you can’t pay the full amount, call the CRA and ask for a payment arrangement. They’ll usually work with you. They want the money — not the fight.

How to Tell a Real CRA Letter From a Scam

This is the part I wish someone had told my mom twenty years ago. Scammers target newcomers more than anyone else because they know the system is unfamiliar and the fear is real.

Here’s how to spot the difference.

Real CRA contact looks like this:

• A letter in the mail, in a plain envelope, on official letterhead
• A message in your CRA My Account online portal
• Occasionally a phone call from a real agent — but they’ll already know your file and won’t pressure you
• Reference numbers, your full legal name, and your SIN partially masked

Scams look like this:

• Text messages claiming you have a refund and need to click a link
• WhatsApp messages from anyone claiming to be the CRA
• Phone calls threatening arrest, deportation, or police if you don’t pay immediately
• Demands for payment in gift cards, bitcoin, e-transfers, or wire transfers
• Emails with links asking you to “verify your information”
• Pressure to act in the next hour, or the next day

If you ever get a call and you’re not sure, hang up and call the CRA directly at 1-800-959-8281. A real agent can look up your file and tell you if there’s actually anything going on. There’s no shame in calling back — it’s the safest thing you can do.

What to Do When a Real Letter Arrives

Open it the same week it arrives. I know it’s tempting to put it on the counter and deal with it later. Don’t. The clock starts the day the letter is dated, and CRA deadlines are real.

Read the first paragraph and the last paragraph. The first tells you what it’s about. The last tells you what to do and by when.

If you don’t understand it, ask for help. A free tax clinic through the Community Volunteer Income Tax Program (CVITP) can read it with you. Search “CVITP near me” on canada.ca. These are real volunteers, often run through community centres and churches, and they help thousands of newcomers every year.

If the letter asks for money, don’t panic about the number. Look at whether it’s a final amount or a proposed amount. Look at the deadline. If you can’t pay in full, call and arrange a payment plan. Interest compounds daily, but the CRA is far more patient with people who communicate than with people who hide.

Set Up CRA My Account — Even If You Don’t Think You Need It

This is the single most useful thing you can do after landing in Canada. CRA My Account is an online portal where you can see every letter the CRA has ever sent you, check your tax filings, see your benefit payments, and upload documents when they ask for proof.

It also means that if a letter gets lost in the mail (which happens more often than you’d think), you still have a digital copy.

To sign up, go to canada.ca and search “CRA My Account.” You’ll need your SIN, your date of birth, your postal code, and an amount from a recent tax return. They’ll mail you a security code within about two weeks to finish setting it up. It’s annoying but it only happens once.

For our parents’ generation, this is a hard sell. They don’t trust online accounts with the government. I understand that — but the trade-off is real. Without My Account, every letter is a surprise. With it, you can check your own status anytime you want.

The Mindset Shift

Back home, the tax authority was often a place you avoided. You paid what was demanded, you didn’t ask questions, and you hoped to be left alone. That instinct travels with people when they immigrate. The brown envelope feels like the same kind of letter.

But Canadian taxes are different in one important way: the system is designed to be navigated. There are deadlines, appeal rights, payment arrangements, free help, and a whole online portal that lets you see exactly what’s going on. Almost every problem with the CRA is fixable if you don’t ignore it.

Our parents’ caution wasn’t wrong. They were careful because the systems they grew up with weren’t fair. But the careful thing to do here is the opposite of hiding — it’s responding early, reading the letter, and asking for help if you need it.

With proper guidance, the CRA isn’t scary. It’s just paperwork. And paperwork can be handled.
