CASL Rules for Real Estate Email Marketing in Canada

What CASL actually covers

Canada's Anti-Spam Legislation, in force since 2014, regulates commercial electronic messages: any email, text, or similar message where encouraging some kind of commercial activity is a purpose of sending it. That covers ordinary marketing email outright, and it also covers a one-line message to a single real estate agent about a single listing, if the point of sending it is commercial.

The law applies whenever the message has a connection to Canada: sent from a computer in Canada, sent to one, or accessed through one, regardless of where the sender's business is registered. A realtor working from a US brokerage who emails agents in a Canadian city is inside CASL's reach for that message, the same as a Canadian sender would be.

CASL doesn't carve out an exception for small operators or a single agent sending a handful of emails. The baseline rule is simple to state even though applying it isn't: before you send a commercial electronic message, you need consent, either express or implied, unless a specific exemption in the Act covers that particular message.

Express consent versus implied consent

Express consent is the clean case: the recipient affirmatively agreed to receive commercial messages from you, typically by opting in somewhere and being told what they were opting into. It doesn't expire on its own, only when the recipient withdraws it, but the sender carries the burden of proving it was actually given.

Implied consent is narrower and usually time-bound. The most familiar categories come from an existing relationship: a purchase, lease, or contract within the past two years, or an inquiry about one within the past six months. Neither of those applies to a first-ever message to an agent you've never dealt with, which is the situation most agent-to-agent listing outreach actually starts from.

There's a third implied-consent category that doesn't depend on a prior relationship at all, and it's the one that actually governs cold, professional, business-to-business outreach like this: consent implied from conspicuous publication.

The conspicuous-publication exception, and why it's the one that matters here

CASL treats consent as implied when three things are true: the recipient (or someone representing them) has conspicuously published their electronic address, that publication doesn't come with a statement saying they don't want unsolicited commercial messages at that address, and the message you send is relevant to their business, role, functions, or duties in a business or official capacity.

This is the exception most agent-to-agent listing outreach relies on. A real estate agent's professional email address is routinely published exactly this way: on a brokerage site, in a professional association's member directory, on an MLS agent profile, or handed over on a business card at an industry event, and none of those typically come with an opt-out notice attached. A message about a specific listing, sent to another licensed agent, is relevant to that recipient's role: agents represent buyers, and knowing what's on or coming to market is part of the job the address was published for.

It isn't unlimited license, though. Regulators have been explicit that conspicuous publication sets a higher bar than an address simply being findable online, and it gets assessed case by case: was the publication genuinely tied to a business capacity, and did the message actually stay relevant to that role. An address pulled from a personal social profile, or a message that wanders from the listing into something unrelated, doesn't fit as comfortably.

There's also no fixed calendar attached to this category the way there is for a relationship-based one. That's not the same as a permanent license: if an agent's address comes down from the public listing, or they've asked not to be contacted, the basis for relying on it is gone from that point forward.

Why the business-to-business exemption is narrower than it sounds

A separate exemption in CASL's regulations covers commercial messages between an employee, representative, consultant, or franchisee of one organization and the equivalent at another organization, as long as the two organizations have a relationship and the message concerns the receiving organization's own activities. Where it genuinely applies, this exemption is generally understood to relieve the sender of the Act's consent, identification, and unsubscribe requirements for that specific message. In practice it is interpreted narrowly, and it rarely covers a first-touch listing email.

The word doing the work there is relationship, and it means a relationship between the organizations, not just professional courtesy between two people who happen to work in the same field. Two brokerages that have never done business together, and two agents who've never worked a deal together, don't meet that bar just because both are licensed real estate professionals.

Regulators and the courts have taken a narrow view of this exemption where senders tried to stretch it to cover ordinary cold outreach. The practical takeaway for a first-touch listing email to an agent your brokerage hasn't worked with before: build the message around the conspicuous-publication consent path above, with full identification and an unsubscribe link included, rather than assuming this exemption covers it.

What every message needs, no matter which basis it relies on

Outside the narrow business-to-business exemption, every commercial electronic message needs to identify who sent it and give the recipient a working way to opt out, regardless of whether the consent behind it is express or implied. In practice, that comes down to a short list of concrete requirements.

These aren't formalities to satisfy on paper. An unsubscribe link that's technically present but buried, slow, or asks for more than an email address to process doesn't meet the standard; CASL's own guidance describes it as something a recipient can act on without difficulty or delay.

Building every message to include these regardless of which consent basis you believe applies is the safer default. Consent categories can be argued about after the fact; a message that already identifies its sender clearly and lets someone opt out in one step removes an entire category of dispute before it starts.

• →Clearly identify the sender, by name or the name the business operates under
• →Include a valid mailing address, and keep it valid for at least 60 days after the message goes out
• →Give at least one other way to reach the sender: phone, email, or a website
• →Provide an unsubscribe mechanism that works at no cost to the recipient, through the same channel the message arrived on
• →Process an unsubscribe request without extra steps, no later than 10 business days after it comes in

How this compares to CAN-SPAM for realtors working both sides of the border

CAN-SPAM, the US federal law covering commercial email, starts from the opposite default. It doesn't require consent before you send a first commercial message to someone; instead it requires you to honor an opt-out once they ask for one. That's a different bar than CASL's, not a lower one.

A CAN-SPAM-compliant message still needs accurate sender and routing information, a subject line that doesn't misrepresent the content, a valid physical postal address, and a working opt-out mechanism that stays live and gets honored within 10 business days. If the recipient hasn't already given affirmative consent, the message also needs a clear, conspicuous statement that it's a solicitation.

For a realtor sending listing outreach into both countries, the practical consequence is that CASL is the stricter standard on when consent is required, while both laws converge on requiring clear identification and a working unsubscribe. Build a message to satisfy CASL's identification and unsubscribe rules and it will generally clear CAN-SPAM's version of the same requirements too; the reverse isn't guaranteed.

How Sendehm is built around this

Every campaign sent through Sendehm carries the realtor's own identity as the sender and a working unsubscribe link, on every message, to every recipient, regardless of which consent basis would apply to that particular send. That isn't an optional setting to turn on.

The audience for a campaign is licensed, verified real estate agents whose professional contact information is associated with their business role, and the message itself is a listing notice, information relevant to another agent's work representing buyers. Anyone who unsubscribes or bounces is suppressed from future sends automatically, not just held out of the one campaign they opted out of.

None of this replaces judgment on your side. Consent under CASL is assessed message by message: the platform is built to keep the structural requirements, identification, unsubscribe, a verified and business-relevant audience, in place on every send, but keeping the content of any given campaign genuinely about the listing, and not drifting into something unrelated to the recipient's professional role, is still on you as the sender.

This is general information, not legal advice

Everything above describes CASL's structure as generally understood and publicly documented by the CRTC and Innovation, Science and Economic Development Canada. It isn't legal advice, and it isn't a substitute for reviewing your own specific situation, especially an unusual list, a cross-border campaign, or anything connected to an active complaint or enforcement inquiry, with a lawyer familiar with CASL or with the CRTC's own published guidance directly.

CASL is enforced by more than one body: the CRTC handles the spam provisions directly, the Competition Bureau covers false or misleading representations, and the Privacy Commissioner covers address harvesting and personal information. Enforcement history shows regulators reading the exemptions narrowly where a sender stretched them past what the text actually supports, so two businesses emailing each other isn't, on its own, the end of the analysis.

Common questions

Can realtors send cold email to other agents in Canada?

Yes, but it isn't unconditional. CASL still requires some form of consent, or a narrow exemption, before an agent can email another agent who hasn't previously interacted with them. In practice, the relevant path is implied consent from conspicuous publication: the recipient's professional address was published in a business capacity, without an opt-out notice attached, and the message is relevant to their role as an agent. Every message still needs sender identification and a working unsubscribe.

Does handing someone a business card count as consent to email them?

It can, depending on the circumstances. If someone gives you their business card with an email address on it and doesn't say they don't want unsolicited messages, and what you later send relates to their business role, that supports implied consent through conspicuous publication. It isn't an unlimited license, though. The message still has to stay relevant to their professional capacity and can't wander into unrelated marketing.

Is the business-to-business exemption enough to skip consent for listing outreach?

Usually not for a first-time message. That exemption requires an existing relationship between the two organizations, not just that both people work in real estate, and regulators and the courts have interpreted it narrowly. For a first-touch email to an agent whose brokerage hasn't worked with yours, plan around consent and the identification and unsubscribe requirements rather than this exemption.

How is CASL different from CAN-SPAM for a realtor working markets on both sides of the border?

CASL generally requires consent before you send. CAN-SPAM doesn't require consent before the first message but requires you to honor an opt-out afterward. Both require clear sender identification and a working unsubscribe. Building a message to CASL's stricter standard will generally satisfy CAN-SPAM's requirements too.
