I'm not sure if the RCMP would ever deal with squatters outside of a court order to do so, as they have no method of determining whether somebody is a legal resident, or a squatter?
I guess not in all cases though.
Police will summarily remove you from an Air BnB or a hotel suite, with no court order. They will not do the same at a more conventional long-term residence.
I'm guessing nobody here has encountred such a situation.
