It's not really an OTC stock in the way you're thinking. This is a completely normal reporting Canadian company. They will not operate like a pink. Honestly, the website newcannabisventures.com is pretty on point with keeping readers updated. Other option would be to create a free SeekingAlpha account and follow the company. If you download the app you'll get a notification when anything happens.
Again, this is not like one of the pos US weed companies. It's going to do very well long term and is positioning itself accordingly. Great board and the head of the pharmaceutical division is the ex-CEO of Purdue pharma. Also have a decent amount of cash to finish their main expansion project.
