Police in riot gear cleared the main protest hub in downtown Ottawa Saturday, using batons and pepper spray and making dozens of arrests, as they worked to flush out a hard core of demonstrators occupying the Canadian capital.

In a day-long show of force, hundreds of officers pushed into the city center - facing off in tense scenes with determined protesters who hurled gas canisters and smoke grenades at advancing police, linking arms and chanting "freedom."

By the afternoon, police backed by tactical vehicles and overwatched by snipers had cleared Wellington Street in front of the Canadian parliament - the epicenter of the trucker-led demonstrations that began almost a month ago over COVID-19 health rules.

Trucks were towed and tents, food stands and other structures set up by the demonstrators were torn down. 

Ottawa interim police chief Steve Bell told a news conference "very important progress" had been made on day two of the operation to clear the protesters, though he cautioned it was "not over."

On side streets around the parliament, a police message boomed by loudspeaker urged die-hard demonstrators, "You must leave, [or] you will be arrested."

A few hundred ignored the order, braving bone-chilling cold into the night while waving Canadian flags, setting off fireworks at a barricade and singing the 1980s rock anthem, "We're Not Gonna Take It."

Bell said 170 people had been arrested since the start of the operation, 47 of them on Saturday.

He also called out parents for putting their children "at risk" by bringing them "to the front of our police operation."

As tensions ratcheted up, police used what they called a "chemical irritant" - apparently pepper spray - against protesters, who they said were being "assaultive and aggressive," launching gas canisters at officers.

Organizers of the so-called "Freedom Convoy" meanwhile accused police of beating and trampling demonstrators, telling supporters to leave "to avoid further brutality."

Some truckers had chosen to depart on their own as the police closed in, driving their 18-wheelers away after weeks of demonstrations that at their peak drew 15,000 to the capital. 

Others were defiant. "I'm not leaving," said Johnny Rowe at the start of the day.

"There's nothing to go back to," he told AFP. "Everybody here, myself included, has had their lives destroyed by what's happened in the past two years."

"I'm freezing my ass off, but I'm staying," echoed a protester who gave his name only as Brian.

An AFP journalist also observed a steady flow of protesters leaving the area.

"We're taking it somewhere else," said musician Nicole Craig, her husband Alex adding: "Even if the truckers have left town, the protest will continue. This fight is not over."
