We offer black control knobs that are compatible with the 2017 Montana High Country with Irvine Shades. These knobs typically fit manual roller shades with an outside diameter of about 3/4 inch to 1 1/8 inch on the shade tube. We do ship to Canada, though additional shipping charges may apply for international orders. A recommended part is the Irvine Day/Nite End Bracket with Black Dials, which fits the specifications you provided. If you need further assistance or specific measurements, please let us know to ensure you get the correct part.
