Hi Dave
It is a long process (I know - I'm in the midst of doing the same thing) the web site is:
www.collectionscanada.ca/index-e.html
at right, click on Canadian Genealogy Centre
Top click on Sources by Topic
Left click on Immigration
Left Passenger Lists 1865 - 1935

It would help if you knew the date or where he docked: you order the films (from your Library) and use their reader.
Good luck
