I'm from Ontario, Canada....and my high school also had a computer lab full of Commodore PCs (I remember some of them were Commodore Colts). Before that it was full of Commodore C64s and PETs.
Commodore Canada had a really successful connection with the school boards in Canada. I think in the US Apple computers were more common in schools, but here in Canada, Commodore had the educational market (elementary and high school) sewn up.
The funny thing was that they seemed to have skipped the Amiga line altogether (going from 8-bit Commodores to Commodore-made PCs) BUT all the Commodore PCs were equipped with 1084 monitors (what a waste to use them only on EGA graphic PCs!).
