Do you have any statistics to support that claim?
It's difficult to get accurate statistics when the application form provided for newborns does not contain any box for citizenship of parents. As far as I know the only known statistics are those done by a single hospital in Richmond BC, where according to a Liberal MP, a fifth of the births were to foreign parents. I don't think we can extrapolate from that across the country, of course, but it doesn't take a genius to figure out if 300+ anchor babies are born in this one hospital in a year there are many, many more.
So what exactly is the problem of emulating those vile fascist regimes of Australia, Sweden, the United Kingdom and France in requiring more than just the mother's temporary presence in Canada to grant citizenship to the baby?
