Email remains one of the most effective channels a Canadian realtor has, which is precisely why the rules around it deserve more attention than they usually get. Canada's Anti Spam Legislation, universally shortened to CASL, sets out obligations for commercial electronic messages that are stricter than the equivalent rules in most other countries, and real estate is an industry that runs on accumulated contact lists.
This is a general overview rather than legal advice, and any agent with a specific concern should speak to a lawyer or to their brokerage's compliance resource. What follows is the practical shape of the obligations, aimed at helping you build a list you can actually use with confidence.
Consent Is the Centre of the Framework
CASL is built around a straightforward principle. Before you send a commercial electronic message, you generally need consent, and that consent comes in two forms.
Express consent is what it sounds like. The person actively agreed to receive messages from you, and they did so knowing who you are and what they were agreeing to. A checked box on your website form that the visitor ticked themselves, a verbal agreement you documented, or a signup at an open house all qualify if they were genuinely affirmative. Express consent does not expire on its own, which makes it the most valuable kind of permission you can hold.
Implied consent covers situations where a relationship reasonably suggests the person expects to hear from you. An existing business relationship, such as a client whose transaction closed, generally supports implied consent for a defined period. An enquiry made to you also supports it for a shorter window. The critical point is that implied consent is time limited. It runs out, and continuing to email someone after it has lapsed is where otherwise careful agents get into difficulty.
There is also the case of a business email address published publicly without a statement restricting unsolicited messages, where the message is relevant to that person's role. That pathway is narrower than agents often assume and should be used carefully rather than treated as a licence to email every address you can find.
What Every Message Must Contain
Consent alone is not enough. Each commercial message must identify who is sending it and give the recipient a straightforward way to stop receiving them.
Identification means your name, and where relevant the name of the brokerage on whose behalf you are sending, along with a mailing address and a way to contact you such as a phone number, email address, or web address. A footer with a name and nothing else does not meet the requirement.
The unsubscribe mechanism must be easy to use, must be available for a period after the message is sent, and must be honoured promptly. Burying the link, requiring someone to log in, or asking them to reply and explain themselves are all approaches that create risk and, more practically, annoy people who might otherwise have thought well of you.
The Record Keeping Nobody Wants to Do
The obligation that most often goes unmet is documentation. If a question arises about whether you had consent, the burden of demonstrating it sits with you rather than with the recipient. That means keeping a record of how and when consent was obtained.
The good news is that a properly configured CRM does this automatically. When a form on your website captures a contact, the system can record the date, the source page, the consent language displayed, and the fact that the box was actively ticked. Contacts added manually should carry a note describing how consent was obtained. It takes a few seconds at the point of entry and is nearly impossible to reconstruct years later.
Where Realtors Most Commonly Go Wrong
The most frequent problem is the imported list. An agent joins a new brokerage, inherits a spreadsheet, or buys a list of local homeowners and starts sending a monthly newsletter. Consent does not transfer because a file changed hands, and the fact that recipients live in your farm area is not a form of permission.
The second is pre ticked boxes and bundled consent. Consent should be an affirmative act, which means the visitor ticks the box rather than untickng it, and the language should describe what they are signing up for.
The third is the expired implied consent that quietly became a habit. A contact enquired about a property two years ago, never responded again, and has been receiving your market update ever since. Set your CRM to flag contacts whose implied consent window is approaching its end, and either convert them to express consent by asking directly or remove them.
Compliance and Deliverability Point the Same Direction
Here is the part that turns an obligation into an advantage. Everything CASL requires also happens to be what email providers reward. Sending only to people who agreed to hear from you produces higher open rates and fewer spam complaints. Honouring unsubscribes promptly protects your sender reputation. Removing stale contacts improves your engagement metrics, which improves inbox placement for the contacts who remain.
Agents who treat a large list as an asset in itself often have worse results than agents with a third of the volume and genuine permission, because the large list drags their deliverability down and their newsletter increasingly lands in promotions folders and spam traps. Compliance, in other words, is not just risk management. It is the reason your emails get read.
