Partly yes, with the USO incident and all the fall out perhaps, but Canada does have that problem to an extent even if you don't include Genie at all IMO. It's very "what have you done for me lately" especially in sports like tennis which is not very popular here, and only marginally more popular than it used to be since the rise of Raonic, FAA, Shapo, and Andreescu to name the main driving forces.
Essentially I think sports figures are looked at with an air of irrelevance or dislike when they don't do what they're supposed to do, and do it quickly enough for most peoples liking, and that includes the players that work hard, not just the ones that don't. Not saying it's right, I don't think it is and I dislike people that are impatient that way, but it's definitely a prevalent mindset in Canada IMO.
