I think there is a tradition of taking the train to Ottawa to protest. This protest event from 1989 took place in the rotunda of the Via Rail Station, Main Street, Winnipeg.
I have tried to recall and ascribe names to some of the participants. As always I welcome additional information should anyone wish to share in the comments section at the end.
The exhibit begins with a slide show. To see the captions you will have to scroll through the images.
