A convoy of truckers protesting mandatory vaccinations is expected to gather north of Toronto this morning.
The drivers are planning to hold a rally in Ottawa on Saturday, and police there are working with the R-C-M-P and intelligence services to prepare.
Ottawa police Chief Peter Sloly says the protest leaders have been co-operative and shared their plans, but there are concerns far-right extremist groups that have attached themselves to the convoy could spark violence.
Police are planning for as many as two-thousand demonstrators, but say the situation is fluid and changing by the hour.
