Is this really surprising? It's to really hard for me to take this article seriously without the release of said PowerPoint documents. All we have to go on, is that CSEC had access to device IDs and was capable of tracking their locations across airports. And while it's true that metadata can be used to create a graph and hence a wealth of information, ISPs generally are suppose to collect that info. The question is whether the contents of the messages were intercepted. Even then, this article seems to provide a lot of reactions from professors and commissioners without really getting into the details. It's really not that difficult for anyone, yet alone the government, to track MAC addresses on Wifi networks and then start geolocating them. Take for instance this GitHub project: https://github.com/DanMcInerney/wifijammer https://github.com/DanMcInerney/wifijammer You could easily jam Wi-Fi signals or even collect MAC addresses. Collect enough of them from different places, and you can locate people's travelling habits.
