Montreal · Canada
PeeringDB records four exchanges in Montreal and 22 colocation facilities holding 229 network presences. CANIX Montreal is the best connected with 81 participants, while Equinix Montreal has four and MegaIX Montreal two. Most Montreal networks meet inside facilities rather than at an exchange, and a Montreal address reflects a registry entry rather than a device location.
Internet exchanges in Montreal
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.

What a Montreal IP address tells you
Montreal's peering is lopsided. CANIX Montreal has 81 participants against 87 distinct peers recorded citywide, Equinix Montreal has four, MegaIX Montreal two and PIX Montreal none. The weight instead sits in colocation, where 22 facilities record 229 network presences. Cologix MTL3 alone holds 84 networks, more than any exchange in the city has participants, and the five other Cologix sites listed hold 74 between them. eStruxture runs four Montreal facilities with 37 networks in total. No Montreal exchange lists an ASN from the carrier registry.
An address a database places in Montreal can be a device anywhere the announcing network reaches. Operators publish one location for an entire allocation and geolocation providers copy it, so a block registered to a Quebec address keeps that label across every customer using it. Mobile addresses travel furthest from the record. Bell's AS36522, Telus's AS14663 and the Rogers mobile ASNs AS18475, AS20453 and AS36676 carry subscribers across the country and hand them to the internet at a small number of gateways.
Someone checking a Montreal address should read the origin ASN on the prefix rather than the city field. A prefix announced by one of the mobile ASNs is a phone network's address regardless of the city printed, while a prefix from a network peering at CANIX Montreal or racked in Cologix MTL3 is fixed capacity. The netname on the prefix and the holder in the registry record show which of the 87 peers here announces it.
Mobile carriers in Canada
A mobile address in Montreal is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchanges are in Montreal?
PeeringDB lists four. CANIX Montreal has the most participants at 81. Equinix Internet Exchange Montreal records four and MegaIX Montreal two, while PIX Montreal, the former Peer1 exchange, has no participants in the snapshot.
Where do Montreal networks interconnect?
Mostly inside colocation. The city's 22 facilities record 229 network presences against 87 peers at exchanges. Cologix MTL3 holds 84 networks by itself, and Cologix MTL7, Cologix MTL11 and the four eStruxture Montreal sites account for much of the rest.
Does a Montreal IP address mean the device is in Montreal?
No. The label reflects the address an operator registered for the block, which geolocation databases reuse for every address in it. Mobile traffic in particular leaves through gateways that need not be in the city a database names.
