Study in Canada: what age is appropriate to enter a college in Canada?

Anyone can enter a Canadian college - both a yesterday's schoolboy (17-18 years old) and a student who has already graduated from a university (21-22 years old). Older people (from 24-25 years old) who have work experience can also apply if they want to improve their qualifications or get an additional specialty. Motivation can be different, and a flexible education system in colleges makes it possible to satisfy any desires and demands.
