College park (built 1930) in Toronto still has some of the original pendant luminaires from when it opened as a department store in 1930.

Central Tech. High School (built 1915) in Toronto still appears to have some older luminaires in the lobby.
Danforth Tech. High School (built 1923) had some
schoolhouse luminaires in the corridors. However, they were removed
during renovations following a fire.
I think a lot of older school buildings in Toronto still have some original luminaires. However as they're not open to the public, it is rare to find pictures of the interior online.
