2006-07: Zador was selected in the first round (20th overall) of the 2007 OHL Priority Draft.
2007-08: Zador made his OHL debut, allowing 3 goals on 11 shots in one period for the London Knights. He spent most of the season with the Petrolia Jets in the COJHL as a back up to Blair Bennett and was 0-16 with a 7.98 GAA and .833 save percentage as he faced more than 45 shots per game. Zador gained some acclaim for his play with Canada Ontario at the World U-17 Junior Challenge as he posted a 2.40 GAA and .895 save percentage in five games.
2008-09: Zador didn’t see much playing time, splitting the season between London and Oshawa in the OHL and playing with St. Mary’s in the CJOHL. Zador was 6-1 with a 3.64 GAA and .888 save percentage in 10 games as a backup to Trevor Cann in London before going to Oshawa in a mid-season, multi-player and draft pick trade that included John Tavares and Michael Del Zotto. On an Oshawa team that would finish 10 games under .500, he saw a bit more action and was 5-12 plus 1 overtime loss with a 3.95 GAA and team-best .901 save percentage in 18 games. In five CJOHL games with St. Mary’s, he was 4-1 with a 2.80 GAA. Zador started for Team Canada at the WJC U-18 tournament in North Dakota and was 4-2 with a .931 save percentage and 2.42 GAA in six games as Canada finished in fourth place.
2009-10: Zador did yeoman’s work in his first full season with Oshawa on a team that finished 15 games under .500. He was 14-28 with 3 OT losses and had a 4.15 GAA and .884 save percentage. In 49 games, he faced over 1500 shots.
2010-11: Zador was obtained by Memorial Cup-bound Owen Sound in a mid-season trade as insurance for injured Scott Stajcer (NYR) and ended up being one of three goalies used during the Attack’s playoff run to the OHL championship. In 31 regular season games between Oshawa and Owen Sound he was 19-7 with a 3.23 GAA and .888 save percentage (Zador was 9-2 for Owen Sound down the stretch). He appeared in seven playoff games as the Attack also used Stajcer and Jordan Binnington (STL). Zador was 4-0 and posted his only shutout of the year in the playoffs; finishing with a 2.13 GAA and .929 save percentage. He did not see any action in the Memorial Cup as Owen Sound won once in four games.
The top selection in the OHL priority draft in 2007, Zador has battled some nagging injuries as well as playing on inferior teams for most of the past three seasons. The strength of his game is his quickness and agility. Zador is still developing with regards to technique and relies on a butterfly-style while using his height and size to advantage.
Zador will return to Oshawa in the OHL following Lightning camp. Both he and the Generals struggled through a difficult season in 2009-10. He was not selected for Canada's WJC team development camp despite starting for the U-18 team in 2008-09. Oshawa Coach/GM Chris DePiero has added some offensive players to a team that struggled to score last year and the pressure will be on Zador and partner Kevin Baillie to give the team steady goaltending on a nightly basis. Zador has the size and athleticism to play pro hockey. How he performs in juniors this year will go along way to indicating whether he has the tactical skills and emotional make-up to go with his physical attributes.
