This sounds off. Squatter's rights usually apply to land, and in Canada, this:
Acquiring valid title to real property through adverse possession is possible in most Canadian common law provinces.
The fundamental rule is simple enough: if a person occupies land for the required period of time as set out in provincial limitation acts and, during that time, no legal action is taken to evict or intrespass, the ownership in the land goes from the legal owner to the squatter.
The time limitations run from 10-20 years, depending on provincial legislation. You can't just move into an empty house, change the locks, and PRESTO! it's yours. In land cases, the 'squatters' may have paid taxes for many years, and/or used a piece of land whose boundaries were not legally challenged and/or defined and the legal owner did not instigate the process of legally securing her/his property.
