About the only high end school that might interest you is the Canadian Film Centre. Its about as close as you can get to a school like the AFI in Canada. The Canadian Society of Cinematographers offers some workshops from time to time. Capilano University has a large film program and a snazzy new building and offers cinematography courses. However, I've not attended any of these and don't have any first hand reports on them as to how advanced they get. There are several multi-year programs at various universities that are well regarded but are probably too broad and time consuming for your specific interests.
With two features shot and a nice reel I think you'd be wasting your time at any school. Film schools don't have the money to rent the latest gear, they tend to use what they have on a fancy camera to lure in the students looking for buzz words like "RED" or "ALEXA", and won't get you working with technocranes, large sets with studio rigging or doing big night exteriors with 18ks in condors and wet downs and all that jazz. If you're really new then a school can be a good introduction to lighting and camerawork but you seem to be already at a high level.
