That's surprising, since Videotron doesn't support upstream bonding, although perhaps that's changing in April. It's too bad, I'd consider taking 60/10 cable over 50/10 DSL, but with the CBB rates the CRTC just set, cable will never be competitive with DSL.
Quite puzzling that they haven't enabled bonding yet. They certainly have all the equipment so support should be little more than a few administrative commands away to enable it on their CMTS.
As for CBB rates, cable certainly lost a lot of its potential appeal there. Only time will tell how that shakes out.
