Thousands of marijuana activists from key Canadian cities puffed joints in public on Saturday as part of the Global Marijuana March - a worldwide protest on cannabis prohibition.

Montreal, Ottawa, Vancouver and Winnipeg held similar protests which took place simultaneously in 239 major cities across the globe, according to a Cannabis News' website.

This is the first time Toronto has joined the protests. Pot smokers, mostly recreational users and medical marijuana patients, gathered at Queen's Park in Nova Scotia to protest Canada's Bill C-26, which would impose a minimum of six months imprisonment on Cannabis growers.

CTV News reported that the medical marijuana program has 2,300 registered participants in the city.

"With the federal government talking about pulling exemption holders grow permits and forcing us to buy our marijuana from the government, it's going to put a lot of medical marijuana patients in a precarious situation," Debbie Stultz-Giffin of Maritimers United for Medical Marijuana said in the CTV interview.
