The Fear of Texting Customers: Why Canadian Businesses Hesitate

Many Canadian businesses hesitate to use SMS marketing due to the fear of penalties under Canada's Anti-Spam Legislation (CASL), which can reach up to $10 million per violation. This fear is not unfounded, as the legislation is strict and the consequences of non-compliance can be severe. As a result, businesses may be leaving potential sales on the table by not utilizing SMS marketing, which is used by 68% of Canadians.

The CASL regulations require businesses to obtain consent from recipients before sending commercial electronic messages, including SMS. This consent can be either express or implied, but the burden of proof is on the sender to demonstrate that they have obtained consent. Businesses must also include a functioning unsubscribe mechanism in every message and process opt-out requests within 10 business days.

To comply with CASL, businesses should:

  • Obtain explicit consent from recipients before sending SMS messages
  • Include a functioning unsubscribe mechanism in every message
  • Process opt-out requests within 10 business days

By following these guidelines, businesses can minimize the risk of penalties and ensure that their SMS marketing campaigns are compliant with CASL.

For businesses like Worqd, which offers lead generation and pipeline recovery services, compliance with CASL is crucial. By understanding the regulations and taking steps to ensure compliance, businesses can effectively use SMS marketing to reach their customers and grow their sales. With the right approach, SMS marketing can be a powerful tool for businesses, allowing them to reactivate old leads and follow up with customers quickly and efficiently. By leveraging SMS marketing, businesses can improve their conversion rates and ultimately drive more sales. According to industry research, implied consent for SMS marketing expires after 2 years for purchases and 6 months for inquiries, making it essential for businesses to regularly review and update their consent records.

The good news for businesses in Canada is that SMS marketing is indeed legal, but it's strictly regulated under Canada's Anti-Spam Legislation (CASL). According to the CRTC's own guidance, CASL does not prohibit commercial texts, but rather sets out requirements for sending commercial electronic messages (CEMs). These requirements include obtaining consent, providing sender identification, and offering a functioning unsubscribe mechanism.

For businesses like Worqd, which specializes in lead generation and demand generation, understanding these regulations is crucial. Research shows that implied consent expires after 2 years for purchases and 6 months for inquiries, while express consent has no expiry. This means that businesses must be diligent in maintaining accurate and up-to-date consent records, as the burden of proof lies with the sender.

When it comes to consent, there are two types: express and implied. The CRTC confirms that both types are legally recognized, but express consent is preferred for ongoing campaigns. To ensure compliance, businesses should build consent capture into every SMS touchpoint, using unchecked opt-in checkboxes and logging the exact consent text, date, and method. This is particularly important for Worqd's lead-gen funnels and AI SDR workflows, which rely on fast follow-up and personalized outreach.

Some key considerations for SMS marketing in Canada include:

  • Obtaining consent, either express or implied, before sending commercial texts
  • Providing clear sender identification and contact information
  • Offering a functioning unsubscribe mechanism, such as a "STOP" or "ARRET" keyword

By following these guidelines, businesses can ensure that their SMS marketing campaigns are compliant with CASL regulations. Penalties for non-compliance can be severe, with fines of up to $1 million per violation for individuals and $10 million per violation for businesses.

In terms of statistics, research shows that SMS is the second most popular mobile messaging service in Canada, used by 68% of the population. Additionally, maximum CASL penalties can reach $1 million per violation for individuals and $10 million per violation for businesses. By prioritizing compliance and following best practices, businesses like Worqd can harness the power of SMS marketing while minimizing the risk of non-compliance. With the right approach, SMS marketing can be a valuable tool for generating leads, driving demand, and growing revenue.

The fines don't come from sending a text. They come from not being able to prove you had permission to send it.

Consider Porter Airlines. The CRTC fined the carrier $150,000 for failing to provide a definitive consent history — not for sending unwanted messages, but for lacking

Your CASL-Compliant SMS Playbook: 5 Steps Before You Send

Knowing the rules is one thing — building a send process that survives an audit is another. With CASL penalties reaching up to $10 million per violation for businesses, here's a five-step playbook to run before your first campaign goes out.

Step 1: Capture explicit opt-in the right way. Silence never equals consent, and pre-checked boxes are not valid under CASL. Use an unchecked opt-in box with clear wording about what the person is agreeing to receive. At Worqd, our booking funnel takes this approach — every inquiry requires explicit agreement to be contacted before any follow-up begins.

Step 2: Log the evidence for every single contact. The CRTC is blunt: the onus is on the sender to prove consent exists. Record the date, method, and exact wording for every opt-in you collect. Porter Airlines was fined $150,000 largely because it couldn't produce a definitive consent history — proof gaps are often the weakest point in an audit.

Step 3: Check implied consent before reactivating old leads. Database reactivation is one of the highest-ROI SMS plays, but implied consent expires: two years after a purchase and six months after an inquiry. Verify each contact's consent window hasn't lapsed before texting, and remember that B2B exemptions are often mistakenly over-applied.

Step 4: Build identification and opt-out into every message. Every text must identify who's sending it and offer a working unsubscribe mechanism. Your program should include:

  • Sender name and contact information in every message
  • Bilingual opt-out keywords: "STOP" and "ARRET" (plus "UNSUBSCRIBE"/"DÉSABONNER")
  • Automated suppression that processes unsubscribes within 10 business days — though faster is safer
  • Opt-out mechanisms that stay functional for 60 days after delivery

Step 5: Vet any provider who texts on your behalf. This is the step most businesses skip. Assuming a vendor or agency absorbs the risk is a mistake — the primary organization remains liable under CASL even when a third party sends the messages. Before signing with any provider, ask how they capture and store consent records, how they handle bilingual opt-outs, and what their suppression workflow looks like.

Compliance is a growth asset, not a tax. A consent-clean list converts better, protects your brand, and keeps every future campaign on solid ground.

How Worqd Runs Permission-Aware Follow-Up That Stays on the Right Side of CASL

Speed sells, but in Canada, speed without consent paperwork can cost you up to $10 million per violation. That tension is exactly why fast follow-up and legal follow-up have to be built together, not bolted together later.

At Worqd, every follow-up workflow starts from a simple rule: no message goes out without a consent record behind it. The regulator puts the burden of proof squarely on the sender — as the CRTC's own guidance states, "the onus is on the person who is sending the message to prove they have obtained consent." Our AI SDRs qualify every inquiry in under 60 seconds, but that speed only works because consent is captured before the first text is ever sent — explicit, unchecked, and logged with the date, method, and exact wording the contact agreed to.

That audit trail matters more than most businesses realize. Porter Airlines was fined $150,000 largely because it couldn't produce a definitive consent history, and compliance experts note that proof gaps are often the weakest point in an audit. Our database reactivation work — turning the contacts already sitting in your CRM back into booked calls — follows the same discipline before a single message goes out:

  • Every contact is checked for valid consent — express consent never expires, but implied consent lapses after 2 years for purchases and 6 months for inquiries.
  • B2B contacts get the same treatment, since B2B messages fall under CASL and exemptions are frequently over-applied.
  • Opt-outs are honored with bilingual "STOP"/"ARRET" keyword support and suppression within the 10-business-day window.
  • Sender identification is included in every message, so recipients always know who's texting and how to reach a real person.

One point worth flagging for anyone evaluating providers: hiring an agency doesn't transfer your legal risk. The primary organization remains liable even when a vendor sends messages on its behalf — which is why our outreach is built as permission-aware, personalized contact with relevant accounts, the opposite of a template blast.

The result is follow-up that's fast because it's clean, not despite it. If you want AI-powered follow-up and lead reactivation that stays on the right side of CASL while turning more inquiries into booked calls, book a free growth call — we'll find your bottleneck and show you exactly what compliant speed looks like for your business.

Frequently Asked Questions

Is SMS marketing actually legal in Canada, or is it banned?
Yes, SMS marketing is legal in Canada. The CRTC's own guidance confirms that CASL does not prohibit commercial texts — it sets requirements for sending them: obtain consent, identify the sender, and include a working unsubscribe mechanism.
How big are the fines if I break Canada's anti-spam rules?
Penalties can reach $1 million per violation for individuals and $10 million for businesses. In practice, recent CRTC fines ranged from $5,000 to $250,000 CAD for commercial message violations, so the risk is real but avoidable with proper consent records.
Do I need explicit consent, or can I text existing customers?
Both express and implied consent are legally recognized. Express consent never expires, while implied consent expires after 2 years for purchases and 6 months for inquiries — so check your CRM before reactivating old leads. Note that pre-checked opt-in boxes are not valid under CASL.
Who gets fined more often — people sending texts, or people who can't prove consent?
The fines usually come from missing proof, not the text itself. Porter Airlines was fined $150,000 for failing to provide a definitive consent history, and the CRTC puts the burden of proof squarely on the sender. Log the date, method, and exact wording of every opt-in.
If I hire an agency to send texts for me, does the agency take on the legal risk?
No — the primary organization remains liable under CASL even when a third party sends the messages. Before signing with any provider, ask how they capture consent records and handle opt-outs. This is why Worqd's follow-up is built permission-aware from the start, with no message sent without a consent record behind it.
Do B2B text messages fall under CASL too?
Yes, B2B messages are covered by CASL, and the limited exemptions are often mistakenly over-applied. Treat B2B contacts the same as B2C: get consent, identify yourself, and honor opt-outs like "STOP" and "ARRET" within 10 business days.
