have a look at Salamander, their Synergy series may have something you like. They list several Canadian resellers as well.
Not sure if the primary objective for your needs is a.) a good looking shelf with same/similar design lines as the one you describe or b.) a good quality audio rack. The latter tend to be more open shelving type construction and usually include glass shelves.
You could always try some audio stores like Kébecson or Audio Club in Montreal, most would carry a few lines of furniture. Of course, your local Leons type furniture might have something similar as well. I think they sell the Bell'o line if A/V furniture.
