Another update, this one a lot more cautious: https://www.youtube.com/watch?v=x6fBFdLGUZw This was put out by the protest leaders and they are bracing for a large police presence and arrests.

They have asked for people to get in their cars, perhaps not immediately, but to come to Ottawa: strength in numbers.
