This is the kind of thing I would usually look up myself, but quite frankly I don't feel like wading through who knows how many sites to try and get the answer.
I know that Orser and Browning competeted against either at the Canadians, I also know that Browning and Stojko did the same. However, did all 3 ever compete against either at Canadians? I have no idea what year Stojko went from junior to senior level; if he became a senior by the 88 Canadians, it is possible. I first heard of him I think in 90 when he was already a senior, but I don't know how long he'd been kicking around before then (I never paid attention to the Canadians back then). [By which I am referring to the Canadian Nationals, not the Canadian SKATERS. ]
