Does coverage or access to GLP-1 medications vary a lot by province?

Yes, meaningfully. Public drug plan coverage criteria, wait times for specialist referrals, and even pharmacy availability can differ by province. Private insurance coverage is generally more consistent nationally since it's tied to the employer plan rather than provincial health systems, but public coverage specifically for weight-management indications (as opposed to diabetes) varies more by province.
