Its not clear. Reading the whole article, the RCMP points the finger at the event organizers for the removal of the women. That the organizers are allowed to determine who is permitted to attend.

The part you’re quoting is the local politician politicking a response for damage control purposes. Thats how I read it, anyway. Pierre Pollievre didn’t want them there, he is the Federal Opposition Party Leader, so they were removed.

The ladies can wear whatever T-Shirt they want to meet with the local MP.

PP threw them out because he is a bitch ass little weasel
