I hold dual Israeli and American citizenship and lived in Israel for two years. To be honest, I don't think anybody would care. In my experience, Israelis, for the most part, love Americans. I don't think, however, you would be treated any differently because you're Canadian.
Ultimately, it's just a matter of being a good guest while you're there. If you do that, I'm sure you won't have any problems.
Enjoy the falafel and schwarma!
