The protesters, who first reached the capital on Jan 29, have parked their big rigs on city streets and put up tents and temporary shacks - paralysing the capital to the consternation of officials and the mounting frustration of many residents.
The demonstrations began as protests by truckers angry with vaccine requirements when crossing the US-Canadian border, but have morphed into broader protests against Covid-19 health restrictions and the government of Prime Minister Justin Trudeau. Locals have complained of the ceaseless sound of air horns and of being harassed, insulted or blocked by the protesters.
The truckers and their supporters have dug in, however, saying the protests will continue until the Covid-related restrictions are lifted.
Police on Sunday announced new measures to stop people from helping the protesters keep up their sit-in.
