network resilience, while maximizing the amount of traffic that stays
within Canada for the benefit of all Canadians."

This is incorrect. The main motivation for setting up an IXP is cost,
network efficiency is only important to the degree that it helps reduce
cost.

The main ISPs already peer, so setting up more IXPs does nothing to reduce
their cost. In fact it increases their cost because they need more
equipment and management etc.

I'm also pretty dubious about some of the other claims. Security? How does
an IXP improve security? And I'd be very surprised if any Canada-to-Canada
inter-ISP routing goes through the U.S so the "within Canada" statement
doesn't seem a likely motivation either.

Don't get me wrong, I not anti IXP, I just don't see a need or a business
case for it.

IMHO, the blog post misses the mark. IXPs exist to peer traffic betw=
een ISPs. The reason Canada has so few IXPs, is because it has so very few =
&quot;real&quot; ISPs (and Canada has few ISPs because our telecom policy p=

 In every region in Canada there are (at best), only 2 ways to get to th=
