Perhaps the most entertaining of the Amazing Race franchise at the moment. The Canadian Race is still very challenging and, at times, tough, with many tasks and novelties (the Face-off was adopted in the American version second).
Also, Jon is an absolutely amazing and fitting host. I am impressed by how many of the tasks he is shown to attempt (even if it's all for show).
The host is fantastic. The places in Canada that are visited are breathtaking. Overall, a good show - though the contestants can be a little on the annoying side from time to time.
