Key takeaways
  • Social media platforms have their own promotional-content policies, and industry bodies like Ad Standards Canada publish guidance on influencer disclosure.
  • A material connection is any relationship between the business and the influencer that could reasonably affect how much weight the audience gives the endorsement.
  • The underlying test is always the same: would an ordinary viewer, without digging, understand that this is a paid or incentivized promotion?

Working with an influencer feels informal — a free product, a friendly post, a quick partnership. Legally, it is advertising, and the business behind it can be held responsible if the audience is not told about the relationship. As influencer marketing has become a default channel for Ontario businesses of every size, disclosure has become one of the more common compliance gaps founders overlook.

Influencer marketing disclosure rules exist for the same reason all misleading-advertising rules exist: an audience is entitled to know when they are looking at a paid promotion rather than an independent opinion, so they can weigh the recommendation accordingly.

Why Disclosure Is a Legal Issue, Not Just a Platform Rule

Social media platforms have their own promotional-content policies, and industry bodies like Ad Standards Canada publish guidance on influencer disclosure. But underneath both of those sits a legal principle: presenting a paid or incentivized promotion as if it were an independent, unprompted opinion is a form of misleading representation to the public under the Competition Act. Platform rules and industry guidance exist alongside that legal baseline — they do not replace it.

What Counts as a "Material Connection"

A material connection is any relationship between the business and the influencer that could reasonably affect how much weight the audience gives the endorsement. Common examples include:

If any of these exist and a reasonable viewer would not otherwise know about it, disclosure is generally required.

What Good Disclosure Looks Like

Weak disclosureStronger disclosure
A hashtag buried among twenty unrelated tagsA clear label like "paid partnership" or "gifted" placed prominently
Disclosure only in a caption that gets cut off ("see more")Disclosure visible without the viewer needing to expand or click through
Disclosure only in the video description, not in the video itselfDisclosure stated in the content itself if the platform and format allow it
Vague language like "thanks to [brand] for this"Explicit language making clear the content is sponsored or compensated

The underlying test is always the same: would an ordinary viewer, without digging, understand that this is a paid or incentivized promotion?

Who's Responsible — the Brand or the Influencer?

Both can be, but the business behind the campaign should not assume the influencer's own choices fully insulate it. A business that pays for a promotion and does not confirm proper disclosure happened can still be exposed if the resulting content is misleading. This is why written influencer agreements matter — not just for payment terms, but to build disclosure obligations directly into the contract.

Frequently asked questions

Do I need disclosure if I only gave the influencer a free product, not cash?

Generally, yes. A free product or service is still a form of compensation that could affect how the audience should weigh the endorsement, so it typically needs the same kind of clear disclosure as a paid post.

What if the influencer refuses to add proper disclosure?

This is exactly why disclosure requirements belong in a written agreement upfront, with consequences (such as withholding payment or requiring content to be taken down) if the influencer does not comply. Relying on an informal understanding leaves the business exposed.

Does it matter if the influencer has a small following?

The legal principle does not turn on follower count. A small local business working with a micro-influencer is still making a representation to that influencer's audience, and the same disclosure logic applies regardless of scale.

Can I be responsible for an influencer's post I never approved?

It depends on the nature of your relationship and how much control or involvement your business had. A clear written agreement defining approval rights and disclosure obligations reduces this uncertainty considerably.
