Ontario listings on this page are clinics, telehealth services, and pharmacies with an Ontario location in the PeptideBase directory. Toronto, Ottawa, Mississauga, and Hamilton show up as city pages when a city clears the listing floor. A research-chemical vendor that ships from Canada is not in this list and is not labelled as a clinic.
Prescription drugs in Canada are regulated federally by Health Canada. Pharmacy practice in Ontario is overseen by the Ontario College of Pharmacists. Physician licences are a separate question, handled by the College of Physicians and Surgeons of Ontario. Nothing on this page decides whether a specific peptide may be prescribed or compounded.
Some rows are telehealth services that also name other provinces. A telehealth flag means the listing says it offers remote visits. It does not mean every compound associated with that listing is available to an Ontario patient, and it is not a treatment plan.
PeptideBase does not sell peptides and does not publish dosing or injection instructions. City links below compare who is listed in a given Ontario city. The research-vendor directory is the place to read suppliers that are labelled as research vendors rather than as clinics.
