One of the better organizations in the region is Roadcraft Motorcycle Academy – http://roadcraftacademy.com.
They have professional, highly trained instructors that definitely know their topic. Steve McKenna (one of the instructors) is a well known figure on the circuit. Specifically, he has won the police motorcycle games a number of times and has extensive training / experience racing. Bryan has over 40 years experience and was instrumental in the creation of the ICBC Road Sense for Riders manual.
