With just weeks to go before recreational pot becomes legal across Canada, a new report commissioned by Health Canada predicts the demand for it will be substantially higher than widely anticipated.

The report used a 2017 federal survey on cannabis use to estimate how much adult Canadians will consume in the first year of legalization.

It calculated the amount at 926,000 kilograms for both recreational and medical use. That’s a whopping 41 per cent higher than the estimate of 655,000 kilograms by the Parliamentary Budget Officer in 2016.

It’s also higher than estimates by many  private investment companies. A recent report by CIBC World Markets Corp., for example, estimated demand would reach 850,000 kilograms by 2020.

Universities are a place for higher learning, but officials are trying to avoid students getting high while trying to learn, once cannabis legalization comes into effect next month.

At Kwantlen Polytechnic University, Jane Fee, vice provost for students, says the rules still need to be finalized and put through a consultation process, but it's likely none of the four campuses will permit smoking or vaping.

"The idea will be that you shouldn't be in class or you shouldn't be at work if you are impaired in some way, either by alcohol or by cannabis or some other illegal drug," said Fee at the school's Surrey campus on Tuesday.

TORONTO -- Cronos Group Inc.'s shares lost 28 per cent of their value Thursday after a U.S. short-seller accused the cannabis company of withholding information that could be useful to investors.

The Toronto-based company's stock ended the day at $11.77 on the Toronto Stock Exchange, down $4.60 or 28 per cent, eliminating about a week's worth of gains since Aug. 23.

About 14.7 million shares were traded on the TSX, far above the daily average.

Thursday's decline followed a Citron Research report -- published by short-short seller Andrew Left -- that said Cronos has purposely not disclosed the size of distribution agreements with provinces because they are "so small they could never justify the premium investors are paying for the stock."

Lloyd’s of London is to enter the cannabis insurance market, offering cover in Canada to people who produce, distribute and sell it.

The Canadian Cannabis Act, which comes into force in October, allows recreational use of marijuana. The law was passed earlier this summer.

In a note to underwriters, Lloyd’s said: “It is anticipated that this legalisation of cannabis-related activities will give rise to new opportunities for insurers considering writing related risks.”

Insurers at Lloyd’s have been looking for new ways to grow as traditional markets, such as property catastrophe insurance, have been hit by years of falling prices and higher claims because of natural disasters.

 Canopy Growth CEO Bruce Linton told CNBC Friday the cannabis company is well ahead of its rivals in becoming the leading brand in legal marijuana but still needs to improve.

"When I need to find information, I use Google. When I think about web services, I use Amazon," said Linton, whose Canada-based company has partnered with names such as Snoop Dogg and alcohol leader Constellation Brands.

"There's going to be a dominate leading company and we are not that yet," Linton added in a "Squawk Box" interview.

As an employer or employee, how prepared do you think your organizationis for cannabis legalization on October 17? When New York–based advisory firm Mercer posed that question in a survey of Canadian employers, only one third of 366 respondents said they were ready.

Meanwhile, in a separate poll of 1,008 Canadian workers, just 26 percent felt that their bosses were ready for the change.

After a brief selloff earlier in the week, shares of Tilray — the second-largest publicly traded marijuana stock — were up more than 17% Wednesday after the Canadian company posted quarterly sales nearly double a year ago.

For the second quarter, Tilray reported revenue of $9.7 million — topping an the $9.02 million was expected and up from $4.9 million a year ago. The company’s bottom line was also better-than-expected, coming in at an adjusted loss of $0.17 per share where Wall Street analysts had expected $0.85.

lberta was the first province to begin its policy development for cannabis legalization. In June 2016, the government began by commissioning a massive evidence synthesis — the Cannabis Evidence Series — covering five key topics: health effects and harms, medical cannabis, advertisement and communication regulations, experience with legalization in other jurisdictions, and the current Canadian context. It was published in December 2016. This fed directly into the Alberta cannabis framework, which is the beginnings of the proposed legislation that will eventually regulate cannabis production, sales and use.

With marijuana legalization less than two months away, it is unclear whether Abbotsford residents will be able to buy non-medical pot locally on Oct. 17. But they want the option to do so.

Tilray (NASDAQ:TLRY), a marijuana grower based out of British Columbia, reported its second-quarter earnings after the bell yesterday. Though the company generated a meager $17.6 million in revenue during the first half of 2018, its market cap has soared to a towering $4.8 billion in only a matter of weeks.
