Here's what you need to know about the 'Freedom Convoy' demonstration in Ottawa today

Mayor Jim Watson is confident additional police resources will be on the ground in Ottawa by the weekend, as the "Freedom Convoy" demonstration in downtown Ottawa enters a 14th day.

Ottawa police are warning protesters blocking downtown streets they could face criminal charges, and Bylaw Services is increasing fines for noise and idling violations in a bid to break up the demonstration that has gridlocked several downtown streets.

Watson says he has had "encouraging" conversations with Prime Minister Justin Trudeau and federal officials for increased resources, after Ottawa police Chief Peter Sloly said the service needed an additional 1,800 officers and staff to police the demonstration.

"I have every confidence that we'll see additional officers here for the weekend, which tend to be the more challenging times with respect to behaviour down in the red zone," said Watson on Wednesday, noting officers may have to travel from across the country to Ottawa.

"I made it very clear that there's a sense of urgency that we need these officers sooner than later, and that message was received and acknowledged."
