The biggest gatherings were reported in Montreal, Toronto, Vancouver, Ottawa and Halifax.
"I'm really worried about democracy, this country is going in a really bad direction, [Prime Minister Stephen] Harper is taking it in a really bad direction," protester Stuart Basden from Toronto, the Canadian city which saw hundreds of people come out, told The Star.
"Freedom to speak out against the government is probably [in] jeopardy...even if you're just posting stuff online you could be targeted, so it's a really terrifying bill," Basden added.
The ruling Conservative government tabled the legislation back in January, arguing that the new law would improve the safety of Canadians.
