The best shows are those that don't fit a particular category, or that grow to move between categories. Lots of great british TV bounces between comedy and drama (sherlock, cuffs). Some American shows cannot be pinned to a specific age range (simpsons). I still laugh when I see TopGear listed as "informational/other" by my cable company. Also ... (i just noticed) Australian Movies 5230 Belgian Movies 262 Korean Movie…
FWIW, I've seen several Canadian shows. One in particular IIRC is The Transporter series. I don't know how much more there is, but there's definitely more. I think Flashpoint is also on there, which IIRC is produced by a Canadian studio.
If you want to cover everything filmed in canada, that is a very very long list. X-Files, X-men, twilight, the latest godzilla ... it will take a while. But if you expand to to all "canadian content" then be ready for a shock. The first season of the new Doctor Who was a partial CBC production.
