I'm looking for a Toronto or Canadian (mail-order) source for cubed-foam....

By 'cubed-foam', I mean the type of customizable foam that comes in Pelican and similar storage boxes for cameras, video equipment, etc.... (eg. This Stuff).

I'm trying to customize a set of storage drawers to store my collection of SLR lenses and want to find this type of foam that I can customize as I need to.

Any ideas?

Thanks in advance,
Dave...
