Here in Seattle, it's not unusual to see a Canadian manufactured piano.
I myself have owned a Mason & Risch upright, with a fine Otto Higel
player action.  I also have restored a Mason & Risch grand Duo-Art.
I would guess they are as common in Canada as any Duo-Art might be.
The farther you are into the U.S. and away from the border, the rarer
they may be.
