So since Shaw decided to opt out of the wireless provider scene, they have started building wifi access points around Canada instead. They turned on about 9 access points recently in the Lower Mainland and plan to push out thousands more over the next three years in malls and restaurants to compete with Robelus' data plans.
Right now the trial is limited to Shaw internet customers with a @shaw.ca email account. You can see the locations in the map in the link below along with instructions to connect to the Shaw access point.
