They're on Peer1 (Vancouver) bandwidth. While Peer1 is very very very stable (We use it in Montreal) - they are *not* spam friendly, or even "spamvertized" friendly (joe job or not). Adult friendly - yes, stable as all hell - yes. Expensive if you buy directly - very if you have low commits.
In Canada, if you're looking for Adult + Mailer + "Advertised" sites, in a decent level of commit, you'd be much happier going with 360Networks/Group Telecom.
