Where can I get this in Canada (Vancouver)? Would this be the "best", less toxic way (water based) of making raised ground work?

Or any arts and crafts store.

Does anyone by chance knows if I can get celluclay in Belgium?

I`m not sure about Belgium. Ask for ' Instant Paper Mache' at your local hobby shop or arts and crafts store. As far as I can tell, it`s the same product. Just different names.

You can order it from www.hobbylobby.com, or any number of other Arts & Crafts centers. For building built-up ground that's very thick use styrofoam to build up the area then add the actual ground cover. A few suggestions before you use the Celluclay, and yes it is called "instant papier mache: on the bag. Celluclay dries slowly, very slowly and has a tendency to crack. To speed the drying process and avoid the cracking I suggest using either a 50-50 mix of Sculptamold, also available at craft stores, and a generous amount of Elmer's Carpenter's Glue or White Glue. You can also avoid a problem by tinting the groundcover using Acrylic paint, make it dark though. I suggest something like Burnt Umber to give the mixture a good earth color when it dries fully. I've been using this combination for years and with considerable success. When I used Celluclay alone it would sometimes take up to a week or more to fully dry, then I'd have to patch some crakcs and sometimes it would begin to pull off the base. This mixture takes care of nearly every problem imaginable.

Do you guys have Lewiscraft in Vancouver? Or try Michaels... But I got mine at Lewiscraft in Toronto (this was more than a few years ago)...
