Thanks to all for such great contributions to a subject dear to my heart. I'm not nearly as informed as I'd like to be but do live in a home in Scarborough which is 150 years old. My house was previously occupied by a musical family and I was fortunate to lift a few floor- boards during renos and discover hand written sheet music some of which we've since framed and hung in our bathroom. Off the top I can say we found Sweet Betsy From Pike and Nearer My God To Thee (which I believe the band played on the sinking Titanic). These tunes may be post 1860's Ontario but I thought I'd pass along this anecdote which I've always been kind of proud of. We have a copy of a map of our (Ontario) neighborhood which is dated 1861 - and our "farmhouse" is present. I'm not sure about the exact age of the place - but we love it and honestly...I've instruments in every room.
