Can't tell you where to find any materials in Burnaby but I do have a good idea what the 8x8 gasket is intended for. As per DJ88, neoprene works good ( and I agree, just couldn't get my hands on some.) In Calgary one could purchase o-ring material of various diameter and length. The butt ends could be super glued together. Not sure how well that would work since I haven't tried it. I used 3/16" thick food grade rubber (the white stuff and I forget what its called.) It is a fairly soft rubber, shouldn't degrade quickly or contaminate the water. I found it worked just fine. If you have a tight bolt pattern, a thinner or less flexible material may also work.
