Thanks for confirming that fido has rolled out the upgrade.
I'm a fido BYOP user so my LG G6 isn't from fido, it is a dual-sim version.
Is my device covered in this OS upgrade as well?
I'd love to be able to tell you @stephenha but unfortunately I don't have the information.
Contact LG Global Support, they'll have your answer.
Here are their contact methods:
Before contacting them, get the exact model of your device. It's in Settings - General - About phone.
Let me know how it goes!
