Once in the off-school hour, I saw lots of students got on the bus, each with an instructment case, including violin, clarinet, flute, etc. So I believe there must be some musical activities in schools.
Another day I saw a group of students, a wind-instuctment band, casually performing by the road.
Remember the movie "Mr. Holland's Opus"? The scenario is in the States, but I think in Canada situation is similar.
