That's not flaming because I made the same conclusion myself. 
Canarie was the (second) upstream for IETF66 in Montreal, and v6 
connectivity to commercial networks sucked badly to put it mildly 
(Montreal -> Europe went to Japan, Korea, back to NA and then to 
Europe IIRC).  Research network connectivity was excellent.  I sent an 
email about this but never received a response.

I can send traceroutes if someone is interested in what the events 
looked back in July 2006.
