Gordon McGregor, long-time president of Trans-Canada Airlines (Air Canada) was on record as saying he didn't want the Jetliner, as it was too risky a venture.  This became particularly true when the Brits withdrew export approval for the Armstrong-Siddeley Sapphire axial-flow jet engine, under development for the Gloster Javelin interceptor.  Instead of 2 Sapphires, Avro was forced to use 4 much less efficient R-R Derwent centrifugal-flow engines on the Jetliner, which seriously compromised range/payload.
As for orders, I believe Northeast in the US had an agreement to buy 8 to use on Boston/New York-Florida routes, and TWA, then Howard Hughes toy, wanted maybe 20. Hughes used the Jetliner as a sort of personal a/c for a couple of years.
But Avro diden't market the plane.  Essentially a creature of the government, it built 600+ CF-100s and also had this thing called the Arrow on its plate.
Had McGregor decided differently, might have been different.
