Cold Email in Canada: CASL, Consent and B2B Lead Generation That Works

Running B2B cold email into Canada means following CASL, a strict consent-based anti-spam law that requires permission before most commercial emails, not just an unsubscribe link. It also means writing in French for Quebec, sending across several time zones and being honest about how well your data covers Canadian companies. Koldify runs done-for-you cold email campaigns for companies that sell into Canada, and this page covers what we have learned about doing it properly.

Is cold email legal in Canada?

Yes, but only on CASL's terms. Canada's Anti-Spam Legislation (CASL) prohibits sending a commercial electronic message (CEM) unless the recipient has consented, expressly or impliedly, and the message meets form requirements. The US approach (send first, honor opt-outs) does not work here, and the law applies to any message sent to or accessed from a computer in Canada, wherever the sender is based.

The regulator for the email rules is the Canadian Radio-television and Telecommunications Commission (CRTC). What follows is a plain summary of CASL and CRTC guidance. It is not legal advice; for a high-volume program, talk to a Canadian lawyer.

Express consent vs implied consent

Express consent means the person took a positive action to agree, in writing or orally. The CRTC says pre-checked boxes and silence do not count, the sender carries the burden of proving consent, and express consent does not expire until it is withdrawn.

Implied consent exists only in situations the law lists. The two that matter most for sales teams:

• Existing business relationship. A purchase or contract creates implied consent for two years. An inquiry or application creates it for six months.
• Conspicuous publication. This is the basis most B2B cold email relies on, and it is narrower than people assume.

One trap: an email asking for consent is itself a CEM under CRTC guidance. You cannot cold email someone just to ask permission to email them.

Conspicuous publication: the B2B prospecting rule

Under CASL paragraph 10(9)(b), consent is implied when all three conditions are met:

1. The person conspicuously published their email address, or caused it to be published.
2. The publication is not accompanied by a statement that they do not want unsolicited commercial messages.
3. Your message is relevant to their business, role, functions or duties.

The CRTC's FAQ says this sets a "higher standard" than an address simply being available. The address should be directly available to the public, typically indexed by a search engine, and an address you can only find by querying a corporate database does not qualify. The CRTC also says the rule is not "a broad licence to contact any electronic address they find online."

In practice, a company's "Contact our sales team" page listing the VP of Sales, or a speaker bio with an email, can work if your offer fits that role. An email address guessed from a naming pattern, or pulled from a data vendor with no public source, generally will not.

The business-to-business exemption is not a cold email loophole

CASL's regulations exempt messages between employees or representatives of two organizations that already have a relationship, where the message concerns the activities of the recipient organization. The CRTC stresses that the relationship is between organizations, so an employee-to-employee connection alone is not enough. Prospecting a company you have never dealt with does not fit.

There is also a narrow referral exemption: one message to someone referred to you by a person who has a relationship with both of you, naming the referrer. It covers a single email, not a sequence.

What every message must contain

Whatever your consent basis, each CEM must include:

• Identification of the sender and anyone the message is sent on behalf of. If an agency sends for you, both may need to be named.
• Contact information: a mailing address plus a phone number, email address or web address. The CRTC says the address must stay valid for at least 60 days after sending.
• An unsubscribe mechanism that is "readily performed." It must work for at least 60 days, and requests must be processed without delay and no later than 10 business days.

A link to a page with the identification details is acceptable if including them in the body is impracticable. A multi-step unsubscribe that requires a login is not.

How the CRTC enforces CASL

The CRTC can impose penalties of up to $1 million per violation for individuals and $10 million for businesses, and directors and officers can be personally liable. The first major case is instructive for B2B senders. Compu.Finder, a Quebec company selling corporate training by email, received a $1.1 million notice of violation in 2015, later reduced to $200,000 in Compliance and Enforcement Decision CRTC 2017-368.

In that decision the CRTC rejected the company's claims that published addresses created implied consent. Addresses reproduced by third parties did not count, a directory whose terms barred unsolicited messages did not count, and many recipients' published roles were not relevant to the offer. It also rejected the B2B exemption because paying for one employee's course did not create a relationship with the employer.

The Federal Court of Appeal upheld CASL's constitutionality in 2020. The private right of action, which would have let recipients sue senders directly, was suspended by the federal government in 2017 and has not come into force.

Quebec: French language and Law 96

Quebec adds a language layer. The Charter of the French language requires commercial advertising and commercial publications aimed at Quebec, such as brochures, catalogues and order forms, to be in French, with other languages allowed only alongside French. Law 96 (adopted in 2022 as Law 14) strengthened the Charter and created a right of action that lets residents sue over violations.

The Charter does not specifically address one-to-one B2B sales emails, and we have not found OQLF guidance that settles it. Our practical rule: write to Quebec-based prospects in French by default, and make sure any landing page, deck or PDF you link has a French version. That is also simply better outreach, because Statistics Canada reports that 79.9% of Quebec workers mainly used French at work in 2021.

What's different about selling into Canada

Language and tone

Outside Quebec, Canadian B2B buyers read English, and US-style copy mostly works. Tone down the hype: big claims and fake urgency land badly in a market where most buyers have also read CASL-compliant marketing for a decade.

In Quebec, use French written by a fluent Quebec French speaker, not a machine translation of your English sequence. In Montreal, Statistics Canada found 21.0% of workers mainly used English at work in 2021, so an English version is useful when a prospect replies in English. Match their language from the first reply onward.

Who you are emailing

Canada is a small-business market. Innovation, Science and Economic Development Canada (ISED) counts about 1.10 million employer businesses as of December 2024, 98.2% of them with fewer than 100 employees. More than half of the small ones are in Ontario and Quebec.

That means owner, president and general manager titles matter more than in US enterprise lists. In mid-sized firms, the decision maker is often one level higher than you would target in the US.

Time zones and holidays

The National Research Council lists Newfoundland, Atlantic, Eastern, Central, Mountain and Pacific time, plus year-round Yukon time. Saskatchewan mostly stays on Central Standard time all year, and Yukon has used UTC-7 year-round since 2020. Our practical advice (not a study): schedule sends by the prospect's local time, and run Toronto and Montreal in Eastern time and Vancouver in Pacific as separate windows.

Holidays that differ from the US are easy to miss. In 2026, Canada observes Victoria Day (May 18), Canada Day (July 1), the National Day for Truth and Reconciliation (September 30), Thanksgiving (October 12) and Remembrance Day (November 11), and Quebec observes Saint-Jean-Baptiste Day (June 24). Pause or shift sends around those dates.

Data coverage

Apollo and similar databases cover Canada, but none publishes independent, country-level accuracy numbers we could verify. Expect thinner coverage for small firms outside the big metros and for French-language job titles. Pull a test sample, verify it, and check bounce rates before you scale.

The bigger issue is consent, not coverage. A database record shows that an email exists; it does not show where the person published it. For CASL, you need to be able to point to the public source.

Want a second opinion? If you are not sure your Canadian list meets the conspicuous publication test, book a 30-minute call with David at Koldify and we will walk through your targeting and consent basis.

How we run cold email into Canada

Koldify's process is the same for every market at its core, with Canadian adjustments layered on.

1. Infrastructure first. We own and operate our sending infrastructure and send from separate domains, never your main domain. Inboxes warm up for about three weeks, and campaigns typically launch around week four. Our cold email infrastructure guide explains why.
2. List built for consent. We build the list with you and, for Canada, prioritize contacts whose business addresses are publicly published in a context that matches your offer. We record the source for each contact so you can show your consent basis.
3. Offer and copy approved by you. You approve the list, offer and copy before anything sends. Quebec contacts get a separate French sequence.
4. Compliance footer on every email. Every message identifies the sender and your company, includes a mailing address and contact method, and has a one-step unsubscribe that is honored quickly.
5. Local sending windows. Sends are scheduled by prospect time zone, with Canadian and Quebec holidays blocked out.
6. Replies go to you. Interested replies are routed to your team, which handles the conversation, booking and closing.

It is month-to-month, with no long-term contract. You can see the full scope on our cold email services page, or book a call with David at Koldify to talk through your Canadian targets.

Sample cold email for a Canadian prospect

This example assumes the prospect's email was published on their company's team page next to a role your offer serves. Run your copy through our spam word checker before sending.

Subject: Freight audit for [Company]'s Ontario lanes

Hi [First name],

I saw on [Company]'s team page that you run logistics for the Ontario and Quebec distribution centers.

We help Canadian distributors find billing errors in carrier invoices. For a company shipping [volume] a month, that usually means a short review of the last 90 days of invoices before anyone commits to anything.

Would it be worth a 15-minute call to see if your lanes are a fit?

[Your name]
[Title], [Your company]

[Your company legal name]
[Street address], [City], [Province] [Postal code]
[Phone] | [Website]
Don't want to hear from us? Unsubscribe here: [one-click unsubscribe link]

For a Quebec prospect, send a French version and translate the footer too (for example, "Vous ne souhaitez plus recevoir nos courriels? Désabonnez-vous ici"). If an agency sends on your behalf, the footer should make clear whose message it is.

DIY instead?

You can run compliant Canadian cold email yourself. Some tool links here are affiliate links (disclosure).

• Data: Apollo combines a contact database with email verification. As of October 2026, third-party sources list the Basic plan at $49 per user per month on annual billing, with a free plan for testing. For CASL, add a column for the public source of each address.
• Sending: PlusVibe starts at $37 a month on Personal (25,000 emails), Smartlead at $39 a month on Base (6,000 sends) and Instantly at $47 a month on Growth (5,000 emails), all as of October 2026. Check that the tool lets you add a custom footer and a one-step unsubscribe link to every email.
• Process: Keep a suppression list that every campaign checks, honor unsubscribes well inside 10 business days, and keep records of where each contact's address came from.

Selling into the US as well? Our cold email USA guide covers CAN-SPAM, which is far more permissive.

How to set up a cold email campaign: the tools you'll need

Some tool links here are affiliate links (disclosure). Prices are as of October 2026.

1. Get your data (who you'll email). Build your list in Apollo by title, industry, company size and location, then export contacts with verified emails. Nerdy Joe is a certified Apollo Managed Services Partner.
2. Buy 2 to 3 sending domains. Never send cold email from your main domain. Use lookalikes (for example, getyourbrand.com). The simplest route is buying them inside your sending tool: Instantly sells done-for-you domains (about $15 a year), Smartlead sells them through SmartSenders, and PlusVibe offers a done-for-you setup. Before you buy, check whether domains bought in a tool can be moved out later; some Instantly users report they can't.
3. Create 2 to 3 inboxes per domain. Google Workspace or Microsoft 365 inboxes, not one big inbox. Instantly sells done-for-you Google inboxes (about $5 a month, or $10 pre-warmed), Smartlead sells pre-warmed Google and Outlook inboxes (about $9 a month), and PlusVibe can set them up for you. Done-for-you setups configure SPF, DKIM and DMARC for you.
4. Warm up for about 3 weeks. Warmup is built into Instantly, Smartlead and PlusVibe. Keep it running after launch.
5. Write and check your sequence. Three to five short emails. Run each one through our free Spam Word Checker.
6. Launch slowly. Start at about 20 to 30 emails per inbox per day in Instantly, Smartlead or PlusVibe, and watch bounces and replies. Use our Cold Email Cost Calculator to size domains, inboxes and spend.

Rather not run it yourself? Koldify, the done-for-you cold email agency where David Tile is a partner, builds and runs all of this on infrastructure it owns. Book a 30-minute call with David.
