Rona Ambrose says she's disturbed by the ads that target B.C.'s Indo-Canadian community.
A clinic in Bellevue, Wash., offers pre-conception gender determination services for what the ads call "family balancing purposes".
Ambrose says it's clear the ads are targeting cultural attitudes that perpetuate discrimination against girls.
She says the ads run contrary to Canadian values where men and women are equal under the law.
Ambrose says she condemns the practice of sex selection through in-vitro technology and is urging Canadian publishers to reject advertisements from clinics offering such services.
