The Ontario Cannabis Store says it received about 100,000 online orders in the first 24 hours that marijuana was legal in Canada.
The government-run operation says 12,000 of those orders came within the first hour after legalization Wednesday morning.
It says customers started receiving their marijuana orders on Thursday.
Recreational cannabis is legal in Canada for those 19 and over as of Wednesday, with each province responsible for regulating the sale and consumption of the drug.
Ontario will have no legal brick-and-mortar cannabis stores until April 1, 2019
