There was a change in the provincial government prior to legalization that probably contributed to this loss. The previous provincial Liberal government had planned to sell cannabis through the provincially owned liquor stores. In June 2018 they lost the election to the Conservatives, who in August 2018 decided not to sell cannabis in the government stores but through private retailers[1]. However, as this was an unexpected change the first private retailers wouldn’t be operational until April 2019 [2]. So from the time of legalization, October 17, 2018 until April 1, 2019 the only way to legally purchase cannabis in Ontario was online and by postal delivery.
Well, for one thing you have to make sure none of the data touches the US or companies that might share data with US agencies (particularly cbp) to avoid screwing over otherwise innocent people who like weed.
