Both politicians are of Indian extraction and descent but not only were born in Canada, but grew up there entirely. It's incorrect to claim that "their country" is India and not Canada. Second generation immigrants are not necessarily well-versed in nor even aware of the goings-on of their ancestral homelands.
Though technically you are correct on both counts. By dint of being born after 1950 but before 1992 to Indian fathers, they may be considered Indian citizens. And based on the ancestral comment in this subthread, it does seem like being an outsource destination is working out for Canada. But only technically correct.
