In 1967 the NHL established the amateur draft, and this tradition continues each year despite the league occasionally cancelling a season or two. The Maple Leafs have drafted at least one player each year, from a wide range of leagues.
Not surprisingly, the Maple Leafs favour the Canadian Hockey League for most of their drafting, with the Ontario League being a particular favourite. Out of the 491 players the Maple Leafs have drafted, 267 have come from the Western Hockey League, Ontario Hockey League, and Quebec Major Junior Hockey League - 54% of all players drafted.
