Canada’s marijuana stocks have been under pressure since the country opened up its market for the recreational use in October. The steep decline in the share values of top producers have investors wondering if the legalization boom for the pot producers is over.

With 65 percent of marijuana stocks losing value in November, last month certainly was not the easiest for cannabis investors. However, the holiday season brings news of three stocks that bucked November’s downward trend. Not only did these stocks finish November higher, each one experienced double-digit percentage gains.

Manitoba's cannabis regulator says stores in the province are following the rules of legalized recreational marijuana.

The Liquor, Gaming and Cannabis Authority of Manitoba says no retailers have been fined and only two cautions have been issued since sales were legalized in October.

One caution was for a broken lock on a storage unit, which was fixed.

The other caution was given to a store that took delivery of cannabis before the shop's retail licence was issued.

Liz Stephenson, the authority's chief administrative officer, says there has been excellent co-operation from retailers.

She also says inspectors are visiting each store on a regular basis to ensure compliance with rules governing storage, signage and more.

The Supreme Cannabis Co. Inc. (FIRE.V) is partnering with a cannabis company founded by hip-hop star Wiz Khalifa to bring the musician's premium pot brand to Canada, but plans to tweak the incoming product to avoid running afoul of Health Canada's marijuana marketing restrictions. 

Supreme Cannabis will  pay Khalifa, the stage name of Cameron Jibril Thomaz, $1 million in cash in addition to about 5.7 million shares in the Toronto-based pot producer in return for exclusive rights to distribute the musician's "Khalifa Kush" cannabis brand and provide consulting services for the next three years.

A medical cannabis company is expanding its sales and production capabilities in southwestern Ontario.

AgMedica Biosience Inc. has acquired two new indoor processing facilities — one in Chatham and one in London. 

CEO Trevor Henry said the company is well-positioned if Health Canada approves the sale of cannabis-infused beverages or edibles.

"We're actually building a plane as we're flying it," he said. "But you know what, when you have confidence in your team, and you're moving through the regulatory hurdles very quickly, we think we're very well-positioned."

London's 10,000 square-foot location will be used for processing, packaging and bottling. The new 300,000 square-foot Chatham facility will be used for future cannabis-plant cultivation.

The marijuana industry has had a truly unforgettable year. In October, Canada lifted nine decades of recreational marijuana prohibition and opened its doors to an industry that, when fully up to speed by sometime near the beginning of next decade, should have the potential to generate $5 billion in added annual sales. Mind you, this is an industry that was already thriving via domestic medical weed sales and exports to medically legal markets.

Adam Bierman could be the poster boy of the modern canna-­business executive. Clean-cut, young, driven, smooth as a vape hit -- about as removed from the bong-bogarting stoner as you can get. He’s also killing it.
