CASL and Cold Outreach: What Canadian Contractors Need to Know Before Emailing GCs

CASL, Canada’s Anti-Spam Legislation, has been in force since 2014. Most Canadian contractors have heard of it. Most don’t know exactly what it covers or how it applies to reaching out to GCs after finding their permit on a city database.

This isn’t legal advice. It’s a plain-language read of what the law says, how it applies to B2B outreach in construction, and what to do to stay clean.

What CASL actually covers

CASL applies to “commercial electronic messages”, emails, text messages, and some social media messages sent for a commercial purpose. Calling a GC on the phone is not covered. Sending a LinkedIn connection request typically is not treated as a CEM under CASL, though the content and intent of the message matter. Email and SMS are.

The law requires that you have consent before sending a CEM, that every message identifies the sender, and that every message contains an easy way to unsubscribe.

Express consent is when someone explicitly opts in, fills out a form, checks a box, replies “yes, contact me.” This is the cleanest form of consent and it doesn’t expire (though it can be revoked).

Implied consent is more relevant for cold outreach. CASL recognizes several categories of implied consent:

That third category is the one that matters most for using permit data to reach GCs.

The published contact information exemption

Under CASL, if a person has published their electronic address and hasn’t indicated they don’t want to receive commercial messages, you can contact them, provided the message is relevant to their business role.

A GC whose email is on their company website or listed on a business directory has published their contact information. If you email them about a construction project related to their work as a GC, you’re operating within the implied consent framework.

This exemption has limits. It doesn’t apply if:

A cold email that says “I saw you pulled a permit for [address] and we do mechanical work in that area” is clearly related to their professional role. A promotional email selling something unrelated is not.

What your emails need to include

Regardless of consent basis, every commercial email you send must:

  1. Identify you. Your name, your company name, and contact information where you can actually be reached.

  2. Make it easy to unsubscribe. This doesn’t need to be a formal unsubscribe mechanism for manual outreach. “Reply to this email and I’ll stop contacting you” works. What doesn’t work is ignoring unsubscribe requests, once someone asks to be removed, the legislation requires you to honour that within 10 business days.

  3. Not be deceptive. The subject line has to reflect what’s in the email. No fake RE: or FWD: headers.

What this means for permit-based outreach

If your outreach looks like this, you’re in reasonable shape:

Where contractors run into trouble is bulk email to purchased or scraped lists, or sending commercial messages to personal email addresses found through means other than the person’s own publishing.

A GC whose gmail address you found on a Facebook group hasn’t published that for commercial contact. Their company email on their website has been.

The practical approach

Three rules that keep you clean:

Use publicly listed business emails only. Company websites, contractor associations, the permit data itself when the contractor name is listed and their website is findable. Not personal emails, not social media accounts.

Stay relevant. Every email should be about a specific project or a specific service they’d plausibly need given their work. Generic promotional emails are higher risk than targeted, specific ones.

Honour opt-outs immediately. The moment someone asks to stop, they stop. Keep a simple list. This is also just good practice, someone who doesn’t want your emails isn’t going to hire you anyway.

A note on scale

CASL’s enforcement has focused on large-scale spam operations, not individual contractors sending targeted outreach to GCs. That doesn’t mean the law doesn’t apply, it does. It means the risk profile of sending 20 targeted emails a week to GCs you found through permit data is very different from buying a list of 10,000 emails and blasting them.

The law is designed to stop spam. Targeted, relevant outreach to a business contact who has published their information isn’t what the legislators had in mind. That said, understand the rules and follow them.
