edit; next time you post place some sort of "watermark" on your images and shrink them to 72PPi/DPi this will lower the resolution but not quality and place a form of copyright onto your images at which point you would have a civil suite.
Actually Canada grants you automatic rights to your works. But unless the images are being used commercially or something, its not worth trying to going to [civil] court over, specially since it'll most likely be next to impossible to find the culprit with just that email.
