There are many similar schools in Vancouver. As mentioned above, VCC also offers such courses. It is said by foreigners that the Pacific Institute of Culinary Arts is still a good school. I also went to this school (at that time, some friends also wanted to learn to cook), just at the entrance of glanville Island. The school is not big, and the reputation seems good. Tuition is very expensive, at least 10000-20000, because tuition includes materials.
