Investors will be on the lookout for the unveiling of a new law in Ontario, expected this week, that defines how cannabis will be sold in retail shops and who can enter the market. Among the provisions is a framework for obtaining licences. This law would come ahead of full-legalization of marijuana in Canada on Oct. 17.
