Canadians who open a US LLC, invoice US clients, use certain US banks, or file a US return without a Social Security Number eventually hear the same instruction: get an ITIN. You do not need to live in the United States to apply. You do need a real IRS reason, a Form W-7 package, and a decision about whether to mail an original passport to the IRS or use a Certifying Acceptance Agent (CAA) from Canada.
MLL works this stack constantly for Canadians who also want a Wyoming LLC, a broader Escape Canada structure, or US banking access. The pattern: people delay the ITIN until a bank or payment platform blocks them — then discover the IRS timeline is measured in months, not days.

Important: Cross-border tax outcomes (Canada departure, treaty claims, US filing obligations) depend on your facts. This guide covers the ITIN application path for Canadians — not Canadian exit tax advice and not a promise that an ITIN creates US tax residency or work rights.
Why Canadians Need an ITIN
An ITIN is a US tax-processing number for people who are not eligible for a US Social Security Number. Common Canadian triggers:
- US LLC ownership — personal tax ID needs for filings or platforms after Wyoming LLC formation (company still gets an EIN separately).
- US-source income that creates a US filing requirement without SSN eligibility.
- US bank or brokerage KYC that accepts ITIN in place of SSN (approval still bank-specific).
- US real estate or investment reporting as a non-resident.
- Spouse / dependent paths on a US return when a family member needs a number — see also ITIN for children.
An ITIN does not make you a US tax resident by itself, does not replace a Canadian SIN, and does not authorize US employment.
ITIN vs SIN vs EIN (Do Not Mix These Up)
| ID | Country / issuer | What it is |
|---|---|---|
| SIN | Canada | Canadian tax / benefits ID — not a US ITIN |
| SSN | US (SSA) | US personal tax / work ID — Canadians usually do not get one without US work authorization path |
| ITIN | US (IRS) | US personal tax-processing number without SSN |
| EIN | US (IRS) | Business tax ID for an LLC/corp — not your personal ITIN |
Most Canadian founders need EIN for the company and, later, ITIN for the person when banking or personal filings require it. They are not interchangeable.
Can You Apply from Canada?
Yes. You do not need a US residential address as a residency requirement for “being Canadian,” but you do need a reliable mailing address for IRS correspondence (CP565 assignment notice). Many applicants use a stable address they control — not a temporary Airbnb that will bounce IRS mail.
You also need a documented reason the IRS accepts. Canadians cannot get an ITIN purely because it “might be useful for flag theory later” with no exception or filing connection.
Two Paths from Canada
Full general walkthrough: how to get an ITIN. Canada-specific emphasis:
Path 1 — DIY: prepare Form W-7 and supporting docs yourself; mail originals to the IRS ITIN unit or appear at a US Taxpayer Assistance Center if you can travel. Mailing a Canadian passport across the border for months is the pain point — especially if you still need to travel, renew status, or open local accounts that require the physical passport.
Path 2 — CAA from Canada: a Certifying Acceptance Agent verifies identity documents so the standard remote path does not require mailing your original passport to the IRS. Package is filed; you wait out IRS processing. This is the route behind US ITIN Assistance.
Field note: for Canadians already mid-move to Paraguay, Mexico, or Panama, the CAA path is usually the only sane option — passports are too operationally important to put in a multi-month IRS mail queue.
Get Your ITIN Without Mailing Your Passport to the IRS
MLL’s remote CAA process is built for non-US persons — including Canadians — who need a clean Form W-7 package without committing an original passport to international mail.
Documents and Form W-7
- Valid passport — preferred standalone proof of identity and foreign status.
- Form W-7 matched to your reason (tax return attachment, banking exception, LLC-related packaging, etc.).
- Supporting exception docs — e.g. return package, bank letter, or entity documents depending on category.
- Consistent personal data — legal name as on passport; avoid SIN/ITIN confusion on forms.
IRS government fee for processing W-7: $0. Any fee you pay is for preparation / CAA / filing help — see Stripe checkout on the service page (prices are not hardcoded in this article).
Common Canadian Use Cases
- Wyoming LLC + ITIN stack — form the LLC / EIN, then ITIN when personal KYC or filings require it. Wyoming LLC package + ITIN assistance.
- Escape Canada packaging — residency + entity + tax pieces; ITIN is often the US personal ID layer inside Escape Canada.
- US banking while still Canadian-resident or after exit — ITIN helps some KYC paths; it does not guarantee account approval.
- US filing with a preparer — once the number exists, hand it to US tax return preparation or start with a US CPA Call.
Timeline and Cost Framing
After a complete filing, plan on typically 2–4 months of IRS processing. CAA packaging can start immediately from Canada; the IRS still controls issuance. Build that lag into any bank-open or filing deadline — “I need it next week for Stripe” is not an IRS-compatible plan.
Deliverable is the CP565 assignment notice mailed by the IRS. Guard the mailing address.
Common Mistakes Canadians Make
- Waiting until a US bank rejects the application before starting a multi-month ITIN process.
- Thinking a Canadian SIN substitutes for an ITIN on US forms.
- Ordering an ITIN with no exception reason because a YouTube video said every expat should have one.
- Mailing the only passport while mid-relocation.
- Confusing ITIN with tax residency or treaty outcomes — different problems.
- Forming a Wyoming LLC and assuming the EIN is enough forever when personal platforms later demand a personal US tax ID.
- Using a temporary US mailbox you will abandon before the CP565 arrives — IRS mail is unforgiving.
- Parallel DIY applications with incomplete packages while a CAA package is also in flight — creates noise and delay.
Practical sequencing we recommend for most Canadian founders: (1) confirm you actually have a US filing / banking / platform reason, (2) form the entity and get the EIN if that is the business layer, (3) start the ITIN early enough that a 2–4 month IRS wait does not block a known deadline, (4) only then open the bank or file the personal return that required the number. Reversing that order is how people end up in rush mode with no leverage over the IRS.
If you are also cutting Canadian tax residency, keep the workstreams separate in your head: CRA departure and treaty analysis are not solved by Form W-7. The ITIN only equips the US side of the stack.

A Wyoming LLC is US infrastructure, not a CRA exit. If you need both the company and a personal US TIN, read Wyoming LLC and ITIN plus Escape Canada for the residency-break work.
Frequently Asked Questions
Can I get a US ITIN while living in Canada?
Yes. Residency in Canada does not block Form W-7. You need a valid reason, identity docs, and a reliable address for IRS mail.
Do I have to visit the United States?
Not on the standard remote CAA path. DIY applicants who choose a Taxpayer Assistance Center would need US access; mail-in DIY does not require living in the US but does create passport logistics.
How long does it take from Canada?
Same IRS window as other non-US applicants: typically 2–4 months after a complete filing.
Do I need an ITIN before a Wyoming LLC?
Not always. Many Canadians form the LLC and obtain an EIN first, then get an ITIN when personal filings or banking require it. Sequence both if your stack needs them together.
Is the CAA path available to Canadians?
Yes. That is the core of US ITIN Assistance — remote certification so the original passport is not mailed to the IRS for the standard CAA package.
Does an ITIN end my Canadian tax residency?
No. Canadian tax residency is a CRA facts-and-circumstances test. An ITIN is a US tax ID only.
