Canadian pharmacies (Shoppers Drug Mart, Rexall, London Drugs and many independents) are licensed provincially, and pharmacists in several provinces can prescribe for minor ailments. Brand-to-generic substitution is decided by the pharmacist under local Health Canada equivalence rules, and the price difference in CAD is usually substantial.
