RE:Canada's canceled licensesPretty sure you just posted a link to a short-seller article. They will spread Fear-Uncertainity and Doubt (FUD) as much as they can to deter buying and invoke selling as that is how they make money from their short positions.
Not all short-sellers are wrong, sometimes they do bring up good points however this guy appears to have completely overlooked Canopy's Position in Germany and the fact that Canopy Medical is already up and running there. No mention of the Canopy USA positioning and what that means to investors as well.
When you read articles you have to know enough about your stock to know what IS MISSING from articles, not just if what is written is truthful or not.
The only way to know fact from fiction is to dig in and know your stock like the back of your hand. That's how you do not get fooled (or less likely at least) and you can better take advantage of someone else's laziness when it comes to doing your research.
