M.J. O'Brien Trophy
Donated by Canadian mining magnate M.J. O'Brien, whose son Ambrose founded the National Hockey Association in 1910. Originally presented to the NHA champion until the league's demise in 1917, the trophy then passed to the NHL champion through 1927. It was awarded to the NHL's Canadian Division winner from 1927-38 and the Stanley Cup runner-up from 1939-50 before being retired in 1950.
NHA winners included the Montreal Wanderers (1910), original Ottawa Senators (1911 and '15), Quebec Bulldogs (1912 and '13), Toronto Blueshirts (1914) and Montreal Canadiens (1916 and '17).
