Princess Anne has not worn one maple-leaf brooch during her visit to Canada, but at least two!
You can see here the differences between the two brooches worn on 10th and 11th November:
10th November: an enamelled brooch, with shades of red, yellow and green; the stem of the leaf if bent towards the left (of the Princess, i.e. towards the right for the viewer)
11th November: a golden brooch, with the stem bent towards the right (left for the wiewer). The overall shape of the leaf is also slightly different:
