The fire broke out around 3:30 a.m., at the hotel in Saint-Côme, about an hour-and-a-half north of Montreal.
Although no one was injured, the building is a total loss, according to police.
Because the incident involves members of the Sûreté du Québec, the case has been handed over to the Montreal police.
The circumstances of the fire are still unknown, but police say the cause is suspicious and have cordoned off the area to investigate until at least the end of the day.
One of Laprise's four business partners, Bruno Beaulieu, is heading the investigation into alleged criminal misspending of former SQ director general, Richard Deschênes.
