Born, raised and lived here all my life and I have never heard of Canadian Maple but a little digging and it is another name for Sugar Maple. William Wood-Write has them.

I might have some but it is mixed up with other maple boards and I can't guarantee it would be Sugar Maple much less be certain it wasn't imported in the first place. Maple like most trees doesn't think much of borders and crosses the line to grow on both sides. It would be cheaper for Vermont (or other eastern States) members to flat rate some to you. Our postage is two or three times yours.
