The Toronto anti-prorogation rally was a success in my opinion. I estimate that there were about 5,000 to 10,000 in attendance. All of Dundas Square was filled with participants.
Maclean's has a photo montage of the event in Toronto on one of its blogs. Included is a photo of a homemade sign about "electoral dysfunction" that I stapled. Note: I did not design the poster. Thanks to Fair Vote Canada for the design.
