Web Hosting in Montreal until recently was a bit behind compared to the rest of the world. This has changed with OVH opening their state of the art green datacenter BHS in 2012. OVH is the #3 largest hosting provider in the world. Source
The opening of this datacenter has resulted in a giant leap forward for Montreal in the Web Hosting industry. Quality and quantity of web hosting providers in the area has improved. A study in 2016 showed that nearly 75 of Greater Montreal businesses have their websites hosted outside of Canada. This number is expected to drop sharply in the next 5 years.
