Health Canada

Health Canada is the federal department of the Government of Canada responsible for national public health policy, and within its mandate the Cannabis Branch (formerly the Office of Medical Cannabis) administers the Cannabis Act and the Cannabis Regulations. Core regulatory functions: (1) Licensing — issuing and managing six classes of cannabis licences (cultivation, processing, sale for medical purposes, analytical testing, research, and cannabis drug licences); maintaining the public Licensed Producer registry; conducting pre-licensing physical site security inspections. (2) Compliance and enforcement — risk-based inspections of licence holders, post-market product testing, recalls, and administrative monetary penalties for non-compliance. (3) Standards-setting — packaging and labelling rules (plain packaging, standardised cannabis symbol, mandatory health warnings rotating across six approved messages), THC content limits (10mg per discrete edible unit, 1000mg per package of extracts, no per-package cap on dried flower), pesticide residue limits, microbial contamination thresholds. (4) Medical cannabis program — the medical cannabis access framework continues under Part 14 of the Cannabis Regulations, allowing patients with a healthcare practitioner's authorisation to register with a licensed seller or grow their own (or designate a grower). (5) Industrial hemp — separate licensing framework under the Industrial Hemp Regulations for hemp cultivation under 0.3% THC. (6) Cannabis Tracking and Licensing System (CTLS) — Health Canada's monthly reporting system that all licensed producers must submit to, tracking inventory movements seed-to-sale at the federal level. (7) Research and surveillance — Canadian Cannabis Survey, monitoring legalisation impacts on public health. Notable Health Canada actions since 2018: 2019 expansion of legal product classes to edibles, extracts, and topicals; multiple voluntary recalls of contaminated or mislabeled cannabis products; 2022 launch of the legislative review process; ongoing tightening of advertising and promotion restrictions under section 17 of the Act. Provincial regulators (LCBO, OCS, AGLC, BCLDB, etc.) handle retail and distribution within provinces, but Health Canada remains the sole federal authority over licensed producers, packaging standards, and the medical program. Importantly, Health Canada does NOT regulate the sale of cannabis seeds for home cultivation by individual Canadians outside the licensed producer system — adult Canadians may legally purchase viable seeds from Canadian seed banks for the four-plant household allowance under the Cannabis Act.
