My favorite BOC note series is the multicolored ones. I love all the notes and thought that the designs were fantastic. I just wish they would have made a $1000 note in the series. I can imagine what it would have looked like, they would use the same portrait of the queen used on the $1, $2 and $20 notes, but it would have a nice deep pink hue. It would be i.e. series 1976 and on the back of the note would be an areal view of Niagara Falls/Horseshoe falls. Or another idea for the back of the note could be a scene from Stanley Park with the totem polls or maybe a view of Toronto from Lake Ontario, or an areal view of The Montreal Olympic stadium. And lastly, a skyline scene of old Quebec City.
