Anti-vaccine protesters gather outside Toronto General Hospital as part of nationwide action

A group of anti-vaccine protesters gathered outside one of Toronto's busiest hospitals Monday after being warned not to harass or obstruct health-care workers.

An organization that calls themselves the Canadian Frontline Nurses orchestrated protests against vaccine certificates in all 10 provinces, including outside Toronto General Hospital. Organizers said they wanted to take a stand against what they called "tyrannical measures and government overreach." On Monday, Toronto Mayor John Tory said police would be "keeping a very close eye on these demonstrations" to ensure they don't obstruct any hospital operations. Toronto police tweeted just after 2:30 p.m. on Monday that there were "no reports of hospital staff or patients being obstructed."
