The short version. Four things decide whether you can advertise: your industry regulator, the general advertising regulator (the FTC in the US, the Competition Bureau in Canada), each platform's own policy, and privacy law. Most businesses are fine — but 24 categories carry real restrictions, and a few are closed on some platforms entirely. Cannabis, firearms, tobacco and political ads are the hardest; healthcare, finance, housing and jobs are allowed but constrained.

This is not legal advice. It is a research starting point built from public regulator and platform policy, with the date each source was last checked shown next to it. Rules change, they vary by exactly what you sell, and platform enforcement often differs from platform policy. Confirm anything that matters with your regulator, your licensing body, or a lawyer before you spend.
The rules that apply to everyone
Whatever your industry, these are the claims that get ads disapproved and businesses investigated. In our experience they cause more real-world rejections than any industry-specific rule.

How Google Ads, Meta, TikTok, LinkedIn and ChatGPT Ads treat each industry. "Certification required" means you must be approved before ads run — usually weeks, not days. Select any industry for the full rules.

Platform policies last checked September 2, 2026. Statuses summarise policy, not enforcement — plenty of technically-allowed ads still get rejected, and appeals are slow.
Common questions
What counts as a regulated industry for advertising?
Any category where a regulator or a platform restricts what you may claim, who you may target, or whether you may advertise at all. In practice that is 24 categories — cannabis, gambling, alcohol, firearms, tobacco, healthcare, finance, insurance, credit, housing, employment, politics and others. Everything else runs on the universal rules: substantiate your claims, price honestly, disclose endorsements.
Can you advertise CBD on Google or Facebook?
Topical CBD only, and only with certification. Google allows topical hemp-derived CBD under 0.3% THC in approved US states once you hold LegitScript CBD certification. Meta requires prior written permission plus active LegitScript certification, US-only, 18+. Ingestible CBD — oils, gummies, capsules — remains prohibited on both, and on TikTok.
Can you advertise cannabis in Canada?
Barely, and only if you are licensed. Google runs a Canada-only, Search-only pilot through 31 December 2026 for Health Canada licence holders and provincially authorised retailers. Everything else is closed, and the Cannabis Act itself bans testimonials, endorsements, lifestyle depictions and any depiction of a person, character or animal — so even permitted promotion is far narrower than normal advertising.
What is a Meta special ad category?
A declaration Meta requires for ads about credit and financial products, housing, employment, or social issues, elections and politics. It exists because anti-discrimination law reaches ad targeting. Declaring it removes targeting by age, gender, ZIP code and detailed demographics, and imposes a minimum location radius. Meta's classifiers can apply it automatically from your imagery, so declare it yourself.
Which industries need LegitScript certification?
Three, plus CBD. Online pharmacies, telemedicine providers that prescribe, and addiction treatment services need it for Google and Meta; CBD advertisers need the separate CBD certification. In-person clinics — dental, chiropractic, physiotherapy, cosmetic — do not need LegitScript, which is the single most expensive myth in healthcare advertising.
Can you advertise legal services on ChatGPT Ads?
No. OpenAI's ad policies prohibit legal advice, legal representation and consumer legal services, explicitly including immigration, personal injury, claims and document preparation. This is one of the sharpest divergences between platforms: Google and Meta run law-firm ads under ordinary rules, while ChatGPT Ads excludes the category outright.
Do advertising rules differ between the US and Canada?
Substantially. Canada limits prescription-drug advertising to name, price and quantity, bans most cannabis promotion outright, requires income claims to reflect typical earnings, and — in Quebec — requires French to be markedly predominant. A campaign that is compliant in the US frequently is not compliant in Canada without a rewrite, which is why this tool covers both.
What are the advertising rules for lawyers?
Set by your state bar or provincial law society, and stricter than any platform rule. Following ABA Model Rules 7.1–7.3, communications must not be false or misleading, specialty claims are restricted to actual certifications, firm identification is required, and solicitation is limited. Most jurisdictions also require a disclaimer that past results do not guarantee future outcomes.
Can I get in trouble for ads my agency wrote?
Yes. Regulators pursue the advertiser whose product is sold, and licensing bodies discipline the licensee whose name is on the ad. Agencies can be liable too, but that does not transfer your exposure. Review claims before they run, keep the substantiation, and treat your agency's compliance assurances as a starting point rather than a defence.
Does Quebec have extra advertising requirements?
Yes — the Charter of the French Language, amended by Bill 96. French must be markedly predominant in commercial advertising, meaning roughly twice the visual impact of any other language. For dynamic displays, the French must show twice as long. Quebec also has its own financial, health and election regulators, and Law 25 governs consent for advertising data.
