its possible. but telus probably wont bond it for you. you could probably get an rt-ac68u from asus and use that in dual wan load balancing mode (meaning it uses about 50% from each connection) balancing the load. in theory this should give you 210/60 judging by your posted speed test results.
the only question is will telus allow 2 seperate connection on 1 ont. or if they will need 2 ont's ( i think they will need 2) and ask if they would do it. i would expect they would do that. but your gonna be paying for 2 connections.
