Re: Help to identify
The only two Canadian manufacturers I can think of off the top of my head are Grew and Peterborough, neither of which are in the lists at Fiberglassics. Not sure when they made the switchover to wood, but your boat has the 1960s look to it and most were going glass by that time. Elgins were also sold through Sears in Canada - not sure who made them for Sears, though. Starcraft made some of them, and I think Lone-Star may have made some, too.
Good luck!
