Are you talking about Ontario? I think it's been up to the ultrasound practitioner's discretion, but in light of recent studies, some are advising their workers to not give out the information. I hadn't heard that it was illegal, thougth.
It's a conundrum, though. If abortion is legal, it has to be legal for everyone, for all reasons. Perhaps more effort should be made to make sure certain immigrants know that around these here parts, we appreciate our daughters.
But if it continues, well, it can't coninue for more than a generation or two. What's a sure-fire way to make sure your son abandons your sexist culture and marries someone from a different background who wont abort her female fetuses? Create a lack of women in your culture for them to date.
