About 30 people rallied on Parliament Hill Tuesday, calling for the legalization and regulation of all drugs.
The demonstration was part of a series organized across Canada.
Rick Sproule, the organizer of the Ottawa event, said that legalizing and regulating all drugs would end the overdose problem.
"People will know what they're taking - they'll know the strength of what they're taking," Sproule told CTV Ottawa.
"When you legalize and regulate....the black market would disappear."
On Wednesday, CTV News and NewsTalk 580 CFRA will team up for a special report - "Dangerous Drugs in Ottawa."
How are drugs like fentanyl coming to our city? Who's at risk, and how can you tell if your child may be involved?
You can join the conversaition on Facebook Live, NewsTalk 580 CFRA, and CTV News Wednesday from 5 to 7 p.m.
