Hello Everyone
I just thought you might find it interesting to know that the iPhone 6 roaming in Canada (specifically in the Greater Toronto Area) and on GSM will roam on Telus' LTE network if you enable data roaming. I thought this was interesting since I haven't seen any "official" article for Verizon allowing roaming on other LTE networks, but I guess since the iPhone 6/6+ support so many bands, it works!

Note that VoLTE currently does not work on Telus' network...they are still in the process of rolling this out.
