My complaint about the lack of Canadian hour-long dramas

What irks me is that in the current television season--the fall of 2007--there are very few new episodes of Canadian dramas set to air. And by dramas, I mean hour-long scripted series ( I don't count sitcoms and reality shows as "drama" like the Cancon execs whose job it is to ensure homegrown drama makes the networks' schedules do). From the four major networks, there are only five Canadian hour-long dramas set to air. CBC is going to be airing the first season of its new family drama Heartland and the second season of its crime world drama Intelligence. City TV is going to be airing its new shows Across the River to Motor City and Blood Ties (which also aired this summer in the States with a successful run). CTV is going to air its second season of the ski resort mystery series Whistler. Global TV is the only network without an hour-long drama on its fall docket--I wonder how that got past the Cancon regulators...

So, my point, of course, is that while, if you go by ratings, it is the hour-long dramas which garner the best ratings on both sides of the border, Canadian networks scarcely produce any. Canada did, during the 90s, have several successful hour-long dramas of its own. Shows such as Street Legal, North of 60, Traders, Neon Rider and Road to Avonlea got well over a million viewers per episode. So what the hell happened to make networks think producing drama was a waste of time? Sure, hour-long dramas cost more money to make than sitcoms and reality shows, but really, the hour-long dramas bring in better advertising revenue, don't they? Someone please explain this to me!
