Sure. We have a grey area here.
Clearly, if John Doe lives in the riding of a federal candidate and also lives in the riding of a provincial candidate, and I just say that the John Doe who lives at 123 Elm Street is supporting me federally, and I give that information to the provincial candidate, who happens to be running in a like-minded fora, a like-minded political party, he could find that information out perhaps by himself. He doesn't need a voters list to find out that John Doe lives at 123.... Or he would have his own list from the provincial authorities. Right?
