Where to purchase Marine Plywood, And recommended thickness 4 casting deck

I'm looking to install a deck across the two front row of seats in my boat so that it has a casting platform so I'm looking to purchase some Marine Grade plywood. Does anyone know a specific store that stocks this product? I tried googling it, but I'm having problems finding it. I live in the Georgetown area, but I realize I probably need to drive up to Barrie just because of the connection to Lake Simcoe and there being a higher probability of someone in that area having it. Obviously the closer the better, but I'll take any suggestions that people may have to offer.

Also, for anyone who has done this type of project before, what thickness is recommended to be used when building the deck? Thanks!

Fairbank Lumber at Keele and Steeles. They have 4 x 8 3/4” roughly $150 a sheet.


Central Fairbank Lumber

Exotic woods in Burlington has it too

I've picked up Marine grade plywood from Home Depot in the past... Do they not carry it anymore?

Home Hardware in Fergus carries it, as does RONA in guelph.
Stuffs not cheap.

Ontario Plastics can get you whatever you need. They typically have a ton of it in whatever thickness you need. Give em a call.

I used standard PT 3/4” plywood. So far so good. I will be painting/sealing it this year, but so far holding up great.

Home depot had it when I built mine. It might be called something else there, but same thing.

I would go synthetic if I was redoing my deck. Lighter and permanent.

I agree.......the new stuff is far superior to any wood product


could put it under water for 10 years and no damage
