I don't know who would sell it in Canada. We sell very few in the US but I do stock them, I probably sell 6 per year but hang on overflows are increasingly less popular than they once were. For pros, it is easy to start as it has a built in siphon priming. It is very quiet as well as it is low flow with a sound dampening foam pad on the lid. It has both surface and bottom intake. On the con side, it is more expensive than many, is quietest with our 1075/2 tubing, the box is metric so some metric tubing or pipe will be required. It also only handles about 350gph.
