I would guess it has something to do with the license number and or details not exactly matching...but that's a guess.
What is the "same thing" they are telling you when they close the case?
It looks like you need a permit from Gatineau and register with CITQ?
Permit Requirement:
Hosts must obtain a short-term rental permit from the City of Gatineau before listing their property on platforms like Airbnb. CITQ Registration:
Anyone offering tourist accommodations for 31 days or less needs a registration certificate from the CITQ.
