"With three offices in Montreal, Quebec and Toronto as well as a data centre in Beauharnois, OVH Canada offers a full range of cloud solutions"

The IPs are probably registered to their Montreal office but indeed, the data centre is in Beauharnois. Think they introduced their services there ~5 years ago.

Since the domain is using an ARIN IP it seems a decent bet that's where they were hosted.
