Common Canadian Representative mistakes, and how to avoid them

Written by Koby Smutylo, lawyer (Law Society of Ontario, called 2001), ISED Canadian Representative since 2010. Last reviewed 20 August 2026.

1. Requesting the letter after the CB asks for it

The CB asks for the representative letter as the last open item, and the certificate waits. Because the letter can be issued before the IC number is assigned (identify the product by PMN and HVIN), order it when you submit the application, not when the CB chases. Same-business-day issue means the delay is short with us, but there is no reason for any delay.

2. Legal name and address mismatches

The applicant's name on the letter must match the application and the intended REL listing exactly. "ABC Technology Co., Ltd." and "ABC Technology Ltd" are different to a reviewer. Use the registered legal name, the registered address, and the same form of both on every document. Trading names and factory addresses cause returns. See attestation letter required fields.

3. Choosing a representative that will not last

A distributor, a customer, a lab or a one-person consultancy will sign today. The question is whether it will answer ISED in year six. The requirement lasts for as long as the product is sold in Canada, and a representative that vanishes puts the certificate at risk when an enquiry goes unanswered. See how long must a Canadian Representative be appointed.

4. Stale contact details

The single most common cause of a missed audit sample request. The regulatory manager who ordered the letter leaves; the mailbox bounces; the representative cannot reach anyone. Give your representative two contacts, one of them a role address (regulatory@), and update them when people change. We confirm contacts annually for that reason. See ISED audit samples.

5. Treating a transfer as a rename

A company rename under the same legal entity is a letter revision. A sale of the product line, or a move of the certificate to a new subsidiary or acquirer, is a transfer: the certificate holder changes, the CB processes it, and the new holder needs its own appointment. Getting this wrong leaves the new holder without a valid representative. See changing your Canadian Representative.

6. Integrators ordering letters for the module maker's certification

A host-product integrator using a certified module does not need a representative for the module's IC number; the module maker does. The integrator needs one only for certifications it holds itself. Check with your CB before ordering. See one representative letter per IC ID.

7. Assuming a US address or FCB covers it

Neither does. The representative must be in Canada, and the FCB is the certifier, not the representative. See from FCC to ISED.

8. A letter without the section 4.1 duties

"We agree to act as Canadian representative" is not enough for most CBs. The letter should expressly accept responsibility for responding to ISED enquiries and providing audit samples at no charge to ISED. If a provider's letter does not say so, ask for one that does.

9. Letting the appointment lapse at the end of a term

Annual terms are the usual culprit: the renewal notice goes to a departed employee and the appointment quietly expires. An appointment with no renewal date removes that failure mode entirely; a register of IC numbers and letter dates removes the rest. We keep one for each client and send it on request.

10. No one knowing who the representative is

Ask a regulatory manager at a foreign manufacturer who its Canadian Representative is for a product certified five years ago, and the honest answer is often "I would have to check." Keep the letter with the certificate in your technical file and record the representative in the same register as the IC number.
