My response to your notion of US bailing out Canada in the First World War didn't mention Canada's prowess in the air.

In 1918, one third of the Royal Air Force fliers in action were Canadians. The top four Canadian aces accounted for 230 enemy planes. No other four fliers in the Allied Forces made records equal to that. The best four German fliers, with vastly better machines, had a record of 246.

For the record, the top Allied fighter pilot of the Second World War, Group Captain Johnny Johnson, DSO and two bars, DFC and bar, ran up his score commanding Canadian Spitfire wings.
