Price fixing legal in Canada?

[Myka]

If you sell "stuff" lower than the MSRP (or lowest "fixed price") on a regular basis, the supply companies will cut you off. This happened last year to a man selling aquarium supplies out of his basement in the Vancouver area. He was undercutting all the big stores, so the big stores complained, and the companies (Euro Reef for example) removed his distributor license (or whatever they call it...?), and quit supplying him.
