Certainly people with dual citizenship would be in a different situation from people with single citizenship. They would become vulnerable to this type of revocation or deemed renunciation, which persons with single citizenship would not become subject to.
I suppose it's true now that people who are not born in Canada and come into Canada can potentially lose citizenship through misrepresentation, which obviously somebody who is born in Canada could not. But this expands the potential vulnerability of people with more than one citizenship.
