I am writing about my experience with broker Grégoire Picard at Royal LePage Altitude in Montreal. July 25: I booked an apartment viewing through their website, choosing a date and time listed as available. July 26: Mr. Picard replied saying viewings must be booked 48 hours in advance. This rule is not stated anywhere on the booking page. His tone was curt and dismissive. After I asked for the next available slot, a viewing was scheduled for July 29. July 29: Mr. Picard arrived early and started calling me 15 minutes before the appointment, saying he was in a rush. I was there 5 minutes early; my wife needed 5 more minutes. He was visibly agitated. The viewing lasted about 8 minutes — no information about the building, lease terms, or amenities was provided. July 29 (evening): I emailed Mr. Picard confirming our interest in the apartment and asking what documents we needed to submit. August 6 (after second follow-up): Only after I sent a second email did Mr. Picard reply — informing me the apartment had already been rented out. We were interested, we were ready to submit documents immediately, and we were likely among the first to view the apartment. But because our email was ignored for over a week, we lost the opportunity entirely. This is unacceptable from a licensed real estate broker.
