Hey Martin,
If you had Rogers, you would have about 20 chinese channels (give or take) mostly from China (but there are a few from here) called the great wall package... Bell only has two - Fairchild (mostly cantonese) and Talentvision (mostly mandarin)... Starchoice has one (Fairchild)... Omni usually has chinese programming on the weekend...usually during the evenings.
One other possibility is this thing called kylintv. They've been hanging around the chinese supermarkets trying to drum up business... from what I can tell, it's chinese programming over the net (IPTV). Don't know how good it is, but I'll take a look later.
