In 2018, Canada was the first G-20 nation to undertake major liberalization of its cannabis policy by implementing the legalization of nonmedical cannabis use and supply for legal-age adults, including commercial, regulated cannabis production, and retail systems. The aims of the legalization policy were to improve cannabis-related public health outcomes, prevent cannabis use among youth, and reduce cannabis crime and illicit market.¹ The federal Cannabis Act set the central legal framework for minimum standards, while allowing variations in provincial/territorial regulations for key parameters (e.g., regarding legal use age, retail distribution models, home-growing, places of use) and so creating a heterogeneous patchwork of regulatory sub-systems across the provinces and territories.¹ By 2024/2025, there were some 3,700 licensed cannabis retailers and 1,000 cultivators/producers, with an annual sales volume of $5.5billion contributing an estimated $16 billion to Canada's GDP. Following a rapid initial ramp-up, it can be assumed that legal cannabis markets have matured to a relatively steady state by now.
