What Canadian law says about advertising peptides

Canadian law defines advertising as any representation that promotes a sale, by any means. For a prescription drug, what may be said to the general public is limited to its names, its price and its quantity. Health claims about the diseases listed in the Food and Drugs Act are barred, and so is any presentation that creates a misleading impression. Health Canada says peptides are generally regulated as prescription drugs, so these rules are the starting point for anyone writing about them.

What counts as advertising

The Food and Drugs Act defines the word:

"advertisement includes any representation by any means whatever for the purpose of promoting directly or indirectly the sale or disposal of any food, drug, cosmetic or device;"

Food and Drugs Act, s. 2, retrieved 4 October 2026.

"Any means whatever" and "directly or indirectly" are wide. A product page, a social media post, a video or an email can each be a representation made to promote a sale.

The limit for prescription drugs

The Food and Drug Regulations set a narrow rule for advertising a prescription drug to the public:

"C.01.044 If a person advertises a prescription drug to the general public, the person shall not make any representation other than with respect to the brand name, the proper name, the common name and the price and quantity of the drug."

Food and Drug Regulations (C.R.C., c. 870), retrieved 4 October 2026.

In plain words: names, price and quantity, and nothing else. Health Canada's general position on peptides is in its April 2026 advisory:

"In Canada, peptides are generally regulated as prescription drugs."

For which peptides are listed by name, read the Prescription Drug List and peptides.

Drugs that are not authorized

A drug that has not been authorized may not be advertised at all. Health Canada reminded the industry of this in 2006:

"It is a violation of the Food and Drugs Act and Food and Drug Regulations to advertise or sell, at retail or via the Internet, drugs that are not approved for sale in Canada."

Health Canada, 6 Oct 2006, Reminder of obligations with respect to the advertising and sale of drugs, retrieved 4 October 2026.

The Regulations say the same for a new drug:

"C.08.002 (1) No person shall sell or advertise a new drug unless (a) the manufacturer of the new drug has filed with the Minister a new drug submission ... (b) the Minister has issued ... a notice of compliance ..."

Food and Drug Regulations (C.R.C., c. 870), retrieved 4 October 2026.

Health claims for listed diseases

Section 3 of the Act bars a kind of claim outright:

"3 (1) No person shall advertise any food, drug, cosmetic or device to the general public as a treatment, preventative or cure for any of the diseases, disorders or abnormal physical states referred to in Schedule A.1."

Food and Drugs Act, s. 3(1), retrieved 4 October 2026.

Schedule A.1 lists conditions including "Cancer", "Depression", "Diabetes", "Hypertension" and "Obesity". This is one reason a responsible page about peptides makes no health claims of any kind.

Nothing misleading, in words or in layout

Section 9 covers the way a drug is presented:

"9 (1) No person shall label, package, treat, process, sell or advertise any drug in a manner that is false, misleading or deceptive or is likely to create an erroneous impression regarding its character, value, quantity, composition, merit or safety."

Food and Drugs Act, s. 9(1), retrieved 4 October 2026.

The Competition Act adds a test that looks past the literal words:

"(5) In proceedings under sections 74.01 and 74.02, the general impression conveyed by a representation as well as its literal meaning shall be taken into account in determining whether or not the person who made the representation engaged in the reviewable conduct."

Competition Act, s. 74.03(5), retrieved 4 October 2026.

In plain words: a page can be misleading even if every sentence on it is true, if its pictures, layout or emphasis leave a false overall impression. And a claim about how well a product performs needs a test behind it:

"in the form of a statement, warranty or guarantee of the performance, efficacy or length of life of a product that is not based on an adequate and proper test thereof, the proof of which lies on the person making the representation"

Competition Act, s. 74.01(1)(b), retrieved 4 October 2026.

What enforcement looks like

Health Canada's July 2026 statement on a permanent injunction against a Canadian online seller of peptides shows that a court order can reach advertising as well as sales:

"Selling unauthorized prescription drugs or making false or misleading claims to prevent, treat or cure illnesses is illegal in Canada."

Health Canada statement, 29 Jul 2026, retrieved 4 October 2026.

"It also cannot advertise or assist others in advertising these products, including through any website or social media platform accessible with a Canadian Internet Protocol (IP) address."

Health Canada statement, 29 Jul 2026, retrieved 4 October 2026.

Our news page on the July 2026 injunction reads that statement line by line.

Does a research-use label change this?

No. Health Canada says that kind of label "does not make these products legal or exempt from regulatory requirements"; the full line is on what "research use only" means in Canada. The advertising rules above have no research-use exception.

What this means for you

When you read about a peptide online, these rules tell you what to expect from a lawful page: no health claims, no claim of results without a proper test behind it, nothing that leaves a false impression, for a prescription drug nothing beyond names, price and quantity, and for a drug that is not authorized, no advertising at all. A page that offers more than that is worth reading with care. If your question is about your own business, ask a lawyer.
