Chris,
WRC must have something. Noah's in Toronto gets US$425 for a bundle of strips sufficient to build a modest size canoe. You can duplicate this amount of strips in cedar for a little more than pine would cost. Just cherry pick the best boards the big-box stores sell and scarf joint the best sections of the cedar to get the strips you need.
Once you're good at scarfing you'll wonder how you got along without it.

: Where I live, I have a hard time finding cedar boards that are relatively
: free of knots, but knot-free pine boards are much easier to find, and much
: cheaper. I know that pine is heavier than cedar, but is that small weight
: difference enough to make a difference after the boat is finished? In
: other words, how much of the total weight of the boat comes from the wood
: itself? Also, are there any other significant differences between cedar
: and pine that I am overlooking? Thanks for your input.
