Key takeaways
- An import-export operation registers an address in three places at once — the RM program account at the CRA, the CARM Client Portal at the CBSA, and your customs broker's file. Keeping them identical is what prevents delayed release of shipments.
- The RM import-export account is a CRA program account opened on your Business Number, but the address that matters most day-to-day is the one inside the CARM Client Portal, where the CBSA now manages commercial accounting and duty payment.
- A home-based importer or a Non-Resident Importer (NRI) can use a commercial business address rather than a residence — and that address is different in purpose from a customs broker's office, which acts as your representative but is not your own address of record.
- A virtual business address in Canada Post Unit/# format gives an importer one stable Canadian street address that works for the RM account, the CARM portal, and CBSA correspondence — without putting a home address on a federal customs file.
Short answer: what address an import-export business needs
To import or export commercial goods in Canada, you register a Business Number (BN) with the Canada Revenue Agency and add an RM program account — the import-export account identified by the two-letter RM suffix. The address on that RM account is a Canadian mailing address that receives registered mail.
But the RM account is only one of three surfaces. Since the Canada Border Services Agency moved commercial importing onto the CARM Client Portal — the CBSA Assessment and Revenue Management system — the address you enter when you register your business in CARM is the one that governs commercial accounting declarations, duty and GST payment, and most CBSA correspondence about your shipments. And if you work with a customs broker — most small importers do — the broker keeps a third address on file as your representative.
The practical question is therefore not "do I need an address" but "which address goes on which of the three records, and can it be the same one?" It can — and keeping it the same is what keeps shipments moving.
This post is the importer-and-exporter layer. For the underlying mechanics of the Business Number itself — the 9-digit structure and the four program accounts — see Do Canadian Small Businesses Need a Business Number?. The rest of this article assumes the BN basics and focuses on the customs side.
The three address surfaces an importer registers
An import-export business does not have one address record. It has three, and each is maintained by a different system.
| Address surface | Maintained by | What it governs |
|---|---|---|
| RM program account on the BN | Canada Revenue Agency | The import-export account record; CRA correspondence about the account |
| Business account in the CARM Client Portal | Canada Border Services Agency | Commercial accounting declarations, duty/GST payment, release decisions |
| Importer file with a customs broker | Your customs broker | Day-to-day clearance correspondence routed through your representative |
The RM account is opened through the CRA when you register for import-export. The CARM Client Portal account is set up separately with the CBSA — registering your business in CARM is now a required step for commercial importers, because CARM is where duties and taxes are accounted for. The customs broker file is the broker's own record of you as a client.
When all three carry the same Canadian street address, a release decision, a duty adjustment, or a CBSA verification letter reaches you predictably. When they diverge — a home address on the RM account, an old office on the CARM portal, the broker's address standing in for yours — correspondence about a held shipment can land at an address nobody is watching. For a goods business, a missed CBSA notice is not a slow audit; it is a container accruing storage charges at the port.
The RM account: what the CRA records
The RM import-export account is a program account hanging off your Business Number, the same way GST/HST (RT) and payroll (RP) accounts do. You open it before your first commercial shipment crosses the border, either at the same time you register the BN or as a later addition through the CRA's business registration channels.
The address the CRA records on the RM account is a Canadian address that reliably receives the account's mail — including registered items, which the CRA does send and which carry response deadlines. A real commercial street address from a mailbox provider satisfies this cleanly: it is a deliverable Canadian street address that can take a signature, and it keeps the RM account record consistent with the rest of the BN file.
One detail specific to importers: the RM account interacts with GST on imported goods. Commercial goods entering Canada are generally subject to GST at the border, accounted for through your import declarations, and — if you are GST/HST registered — recoverable as an input tax credit on your RT account. That ties the RM account, the RT account, and the address on both together. Using one address across the RM account, the GST/HST registration, and the BN file keeps the CRA's records internally consistent and avoids the address-mismatch flags that slow correspondence.
The CARM Client Portal: the address that runs your customs account
For commercial importers, the CARM Client Portal is now the operational centre of the customs relationship. CARM is how the Canada Border Services Agency manages commercial accounting, billing, and payment of duties and taxes. Registering your business in the CARM Client Portal is a required step for commercial importers; the portal is where you see your statement of account, pay duties and GST, and manage who is authorised to act on your behalf.
When you register your business in CARM, you provide a business address. That address should match the address on your RM account and BN file. The portal is also where you delegate authority to a customs broker — instead of the broker's address standing in for yours, CARM lets you keep your own business as the account holder and grant the broker portal access as your representative. This is a meaningful change from the older model: your business address stays on your account, and the broker operates within it rather than replacing it.
Because CARM is a federal CBSA system, the address you register there is part of a federal customs record. A home-based importer who would rather not have a residential address sitting on a CBSA portal can register a commercial business address instead — the same Canadian street address used for the RM account and the BN file.
For the authoritative procedure, the CBSA's CARM information for the trade community is the primary source; CARM functionality and onboarding steps are updated periodically, so confirm the current registration flow there rather than relying on a memorised sequence.
Home-based importers and the Non-Resident Importer case
Two importer profiles have a specific address question that the general "register your business" advice does not answer.
The home-based importer. Plenty of Canadian import-export businesses run from a home — a one-person operation sourcing goods abroad and reselling domestically, with no warehouse and no storefront. That business still needs an address on the RM account, in the CARM portal, and with a broker. Putting a home address on all three means a residential address is now sitting on a federal customs file and, depending on the business structure, potentially on a public corporate registry as well. A commercial business address in Canada Post Unit/# format lets the home-based importer register a real Canadian street address everywhere the customs system asks, while continuing to operate from home. The business is not pretending to have a warehouse; it is separating its customs address of record from its residence.
The Non-Resident Importer (NRI). A Non-Resident Importer is a business located outside Canada that imports goods into Canada as the importer of record — common for foreign sellers who want to deliver landed, duty-paid goods to Canadian customers. An NRI registers for a Canadian Business Number and an RM account and accounts for duties and GST as the importer. The NRI question of "what Canadian address do we use" is real: the operation has no Canadian premises by definition. A Canadian commercial business address gives an NRI a stable in-country address for the RM account and CARM registration. The precise NRI requirements — including security, GST registration, and authority delegation — are governed by CBSA policy, so the CBSA importing commercial goods guidance is the source to confirm them against, not a generalised summary.
A note for anyone arriving from a US importing background: the Canadian system is not the US one. Canada uses the CBSA, the CARM Client Portal, and the RM program account on a Business Number. It does not use a US Customs and Border Protection importer-of-record number, a US EIN, or a US-style customs bond. The concepts do not transfer, and treating them as interchangeable produces incorrect filings. Confirm Canadian requirements against CBSA and CRA primary sources.
A customs broker's office is not your address of record
This is the distinction most new importers blur. A customs broker is a licensed agent who clears your shipments — preparing accounting declarations, calculating duties, and dealing with the CBSA on the technical detail of each entry. Working with a broker is normal and, for many small importers, practically necessary.
But the broker's office is the broker's address, not yours. Under the CARM model, the broker operates as your delegated representative inside your CARM account; your business remains the account holder with its own address. The broker's address can appear as a routing point for clearance correspondence, but it does not replace the business address on your RM account or your CARM registration.
If you let the broker's address quietly become your address of record everywhere, two problems follow. First, CBSA or CRA correspondence addressed to your business — verification letters, account notices, duty adjustments — routes through a third party rather than reaching you directly. Second, if you ever change brokers, your address of record changes with them, and you have to update every record. Keeping your own stable commercial address on the RM account and the CARM portal, with the broker delegated as a representative rather than substituted as the address holder, keeps the customs account anchored to your business.
How a virtual business address fits an import-export operation
A Toronto or Vancouver virtual business address in Canada Post Unit/# format gives an importer or exporter a single Canadian street address that:
- Goes on the RM import-export account as the CRA mailing address — a real street address that receives registered mail.
- Goes on the CARM Client Portal business registration, keeping a residential address off a federal CBSA system.
- Receives CBSA and CRA correspondence about shipments, account changes, and verifications — scanned promptly so a held-container notice does not sit unread.
- Stays the same when you change customs brokers, because the address is anchored to your business, not your representative.
The geography is not incidental. Vancouver is Canada's largest port and the main Pacific gateway for containerised imports; Toronto is the country's largest air-cargo hub and its biggest consumer market. An import-export business with a Canadian-owned commercial address in either city has its customs address of record where the goods and the market actually are. Auteur's Toronto and Vancouver addresses are built for exactly this single-address use — one CRA-ready commercial street address that an importer can put on the RM account, the CARM registration, and every customs document at once.
Reserve a Toronto or Vancouver address and the RM account, the CARM Client Portal, and your broker file can all reference the same Canadian street address from the day you start importing.
FAQ
Do I need a business number to import to Canada? Yes. To import commercial goods into Canada you need a Business Number with an RM import-export program account, which the Canada Revenue Agency assigns. The BN is the identifier the Canada Border Services Agency uses to recognise you as the importer on commercial customs declarations. Casual or personal-use imports are different, but any business importing commercial goods registers a BN and adds the RM account before the first shipment crosses the border.
What is the difference between RM0001 and RM0002?
Both are import-export program accounts on the same Business Number — RM is the two-letter program identifier and the four-digit number is the reference for a specific account. A single business can hold more than one RM account: RM0001 for one import or export stream and RM0002 for a separate one, each filing under the same underlying BN. Most small importers operate with a single RM0001. The reference number lets one business identity carry multiple accounts of the same program type.
How much does it cost to get an import-export licence in Canada? There is no general "import-export licence" with a fee in Canada — the core registration is the RM program account on your Business Number, and the CRA does not charge a fee to open a BN or its program accounts. Costs come from elsewhere: duties and GST on the goods themselves, customs broker fees if you use one, and any product-specific permits or controlled-goods requirements that apply to what you are importing. Use the BizPaL permit-finder tool to check whether your specific goods need additional permits, since requirements vary by product.
Can a Non-Resident Importer use a virtual business address in Canada? A Non-Resident Importer — a business outside Canada importing as the importer of record — needs a Canadian Business Number and an RM account, and a Canadian commercial business address can serve as the in-country address for those records and for CARM registration. The full set of NRI requirements, including any security the CBSA requires, is governed by CBSA policy and should be confirmed against the CBSA's commercial importing guidance rather than assumed, because non-resident requirements differ from those for a domestic importer.
Bottom line
An import-export business does not register one address — it registers three: the RM program account at the CRA, the business account in the CARM Client Portal at the CBSA, and the importer file with a customs broker. The work is keeping all three identical so a release decision or a verification letter reaches you instead of an unwatched mailbox while a container accrues storage charges.
A home-based importer and a Non-Resident Importer both have the same way out of the residential-address problem: a stable Canadian commercial street address. A customs broker's office is the broker's address, not yours — the broker should be a delegated representative inside your account, not a substitute for your own address of record.
Reserve a Toronto or Vancouver address — Canada's largest air-cargo hub and its largest port — and put one CRA-ready Canada Post Unit/# address on the RM account, the CARM portal, and every customs document from the start.
