Yes, the City of Montreal was in possession at the time of permits issued by the provincial government. That was 10 years ago, and the federal regulations had been in force for only a few months. It wasn't yet clear to the municipalities that they had to contact the federal government to acquaint themselves with the regulations.
A stop-work order had been issued so the federal government could form a clear idea of what was going on in Montreal.
