I kind of liked CTV, but only their main news and investigative reports like W5. I never really watched anything else, beyond maybe cartoons when I was a kid.
Really it is a shame that they are gone... indeed I noticed ctvnews.ca and ctv.ca stopped working for me a few months ago. After broadcast TV went digital I did not even bother buying the digital converter/receiver, ctv.ca was my only way. Well nostalgia will not help, I hope for the best for all the amazing journalists and broadcaster that were working there.
Oh ya I remember also liking a science show on weekends when I was a teen, forgot the title of it thought. I think I saw a rerun of it at my gym a few weeks ago.
