The Air Saguenay plane was taking part in a routine sightseeing flight from Lac Long in Tadoussac when it went down, killing everyone on board.
The airline's vice-president said the flight was only supposed to last 20 minutes and weather conditions appeared to have been "perfect" at the time.
Air Saguenay vice-president Jean Tremblay also said the pilot of the aircraft had more than 6,000 hours of flying experience, all of them with Air Saguenay, where he had worked for 14 years.
The bodies of all six people killed in the crash have been found and handed over to the coroner's office.
The Transportation Safety Board has sent a team of investigators to the crash site and the provincial police say they are continuing their own investigation to determine if a criminal element caused the crash.
