Best PLC School in Toronto

I'm looking for peoples' experiences with the different colleges in Toronto that offer PLC courses. I already have a degree from SUNY Buffalo, and I've been working in industrial maintenance for quite some time. So all I'm looking for is a PLC specific set of classes to help advance my career. I'm interested mainly in Humber, George Brown, Sheridan and Seneca. Most of them offer one day a week on weekend classes which is ideal for me. They also typically don't charge anything extra if you're an American student. I would be commuting from Buffalo, NY, which is pretty easy on weekends.

Thanks in advance!
