What is Canada's anti-spam law (CASL)?

CASL is a federal law that aims to protect customers and businesses from misusing digital communication channels such as emails or SMS. It was created in 2014 to reinforce best practices in email marketing and combat spam and any other Commercial Electronic Message (CEM).

The CASL deals with any issue related to theft, phishing, and the spread of malicious software, such as viruses and trojans (malware).

The primary requirements for CASL includes:

Identification – Must identify the sender and include prescribed contact information.

Unsubscribe – The email must include a working unsubscribe button/link.

Unsubscribe Processing – Must deal with all unsubscribe requests in 10 business days.

Consent – Must receive expressed or implied consent from all recipients residing in Canada.

Opt-in – Proof of expressed opt-in.

What's covered under CASL?

CASL applies to any Commercial Electronic Message (CEM) sent from or to Canadian computers or devices in Canada.

A CEM is any message that:

  • is in an electronic format, including emails, SMS, and any social media communications;

  • is sent to an electronic address such as email addresses, instant message accounts, phone numbers, or social media accounts;

  • Include a message encouraging recipients to take part in some commercial activity, such as offers to purchase, sell, barter, or lease a product, a service, land, or an interest or right in land, the promotion of products, services, people/personas, companies, or organizations or offers to provide a business, investment or gaming opportunity.

Fax messages and fax numbers aren't deemed electronic formats or addresses under CASL.

Under CASL, individuals and businesses must obtain consent from users before sending them CEMs, such as emails or texts. If asked, senders should provide proof of this consent.

There are 2 kinds of consent businesses should ask for:

  • express consent

  • implied consent

The consumer has consented to receive a commercial electronic message from you either in writing or orally.

Express consent doesn't expire means there is no time limit unless the recipient withdraws their consent.

What's required in an email when seeking express consent?

When seeking expressed consent from an existing database, there are 4 elements the message must contain to be compliant:

  • Clear purpose or request for consent

  • Contact information of sender or group asking for consent

  • Name of person or group seeking consent

  • Clear unsubscribe option

It is only recognized in certain circumstances of CASL, which are as follows:

  • Existing business relationship

The recipient has made or enquired about a purchase, services, a written contract, or the acceptance of a business, investment, or gaming opportunity from you.

  • Existing non-business relationship

You are a registered charity, a political party, or a candidate, and the recipient has provided you with a gift, a donation, or volunteer work. You are a club, association, or voluntary organization, and the recipient is one of your members.

  • The recipient's email address was conspicuously published or sent to you.

The address was available publicly, and your message relates to the recipient's functions or activities in a business or official capacity.

Implied consent is generally time-limited - typically remains till 2 years of the relationship initiation (e.g., purchase of a product). For subscriptions or memberships, the period starts when the relationship ends.

How are transactional emails handled under CASL?

Although you can send transactional emails CASL, ensure you don't add any reference to personal or product promotion.

And while such emails don't require the recipient's consent, you must still link to the unsubscribe page. One recommendation would be to allow users to opt down or manage their preferences by leading them to the preference center.

Penalties for non-compliance with CASL

Non-compliance with CASL comes with hefty fines:

  • $10 million per violation for a corporation

  • $1 million per violation for individuals

To ensure the quality of your database, you must take inventory and put a plan in place to enforce compliance.

How to be compliant with CASL?

Here are a few things you should do to remain in compliance with Canada's anti-spam law:

3 ways to comply with Canada's Anti-Spam Law -  1. Review email collection method, 2. Conduct email list audit, 3. Ensure email communication comply with CASL regulations

1. Review your email collection methods

Under CASL, you need to have implied or expressed consent for any Canadian resident. So, get consent before sending any email or other CEMs.

2. Conduct an audit

You should conduct a monthly or yearly audit to check each subscriber has given you their express consent. And if you find any anomaly, you can send them an email straight away asking for their consent or opt-in confirmation.

To be CASL compliance, follow all the following:

  • Email should clarify the identity of the person, business, or organization sending the message. Email should identify the Email Service Provider.

  • Email must have a clear and working mechanism for unsubscription.

  • Email must contain a valid mailing address and telephone number, email address, or web address.

Wrap up

Canada’s anti-spam law ensures businesses send messages only after users’ consent. As the world is moving towards digitization, it’s the responsibility of businesses to protect users’ privacy.

A similar law is California's Consumer Privacy Act (CCPA) which aims to strengthen Californians' privacy rights regarding their personal information. If you are a Californian business or have customers based in California, you must read it.
