Mesh Cubes in Ontario Canada?

[Angelgal]

I'm in Ontario, Canada!
I am looking for mesh cubes to build a Chinchilla cage, and a future cavy cage. I'm looking for Mesh cubes/grids such as this, but in black:

I've had no luck so far finding them. I am willing to buy online and pay, shipping is no problem.

Does anyone know a store in Ontario that sells Mesh Cubes?
Does anyone know of an online retailer that sells Mesh Cubes?

Thanks in advance!

I know Home Depot sells the white ones (near Flooring/Shelving area), but I have not seen any other colors anywhere.

Over a month after building my cage, I've found grids almost everywhere (after hunting for a week for them at the time!)... Canadian Tire had a black set and the Loblaws (Superstore) had a multi-color set.
