After clearing a portion of the blockade and making more than 100 arrests on Friday, police on Saturday morning moved quickly to disperse the main portion of the blockade in front of parliament and the prime minister's office, making new arrests.
"We told you to leave. We gave you time to leave. We were slow and methodical, yet you were assaultive and aggressive with officers and the horses," police said in a statement to the truckers posted on Twitter.
Police also used loud speakers to warn the crowd to disperse or face arrest. Some of those arrested on Saturday wore body armour and had smoke grenades and other fireworks in their bags and vehicles, police said.
Again on Saturday, officers smashed vehicle windows to arrest people locked inside, but the overall number of protesters has dwindled dramatically compared with previous days, with a couple hundred remaining near the advancing police cordon.
Some loud bangs of stun grenades were heard, and Reuters witnesses saw some people being pepper-sprayed. Protesters were throwing smoke canisters, police said. Several large trucks that have been parked in front of parliament for weeks drove away as the police approached their position.
No tear gas has been used, police said.
Many of the main organisers have been taken into custody, and some have reportedly left. Accused of being heavy-handed by the protesters, especially when sending in Mounties on horseback, police said there had been no serious injuries.
"We hear your concern for people on the ground after the horses dispersed a crowd. Anyone who fell got up and walked away. We're unaware of any injuries," police said on Twitter.
The protesters initially wanted an end to cross-border COVID-19 vaccine mandates for truck drivers, but the blockade has gradually turned into a demonstration against the government and against Prime Minister Justin Trudeau.
"This is our final stand ... When it ends, it ends and it's in God's hands," said Jeremy Glass, a this, we all need to get back to unity and get rid of this division."protester from Shelburne, Ontario. "At the end of
