The major national networks (Bell, Rogers, Telus, Shaw, Zayo/Allstream)
do peer with each other and some other large / old Canadian networks
(e.g. MTS, SaskTel, Peer1) within Canada. While they do practice peering
protectionism and only purchase transit out of country, the situation is
not *quite* so bad that all traffic round-trips through the US.
Of course if neither side of the conversation has at least one of those
major networks as a transit upstream - which is most of the eyeballs and
most of the important Canadian content - you'll see that hop through
Chicago or Seattle (or worse). Which is exactly the way they like it.
