'Buy local' dairy campaign sparked by trade deal that allows more U.S. milk into Canada

The latest trade deal allowing more U.S. milk to pour into Canada has sparked a rallying cry to buy Canadian dairy. The message comes not only from dairy farmers upset over losing market share but also from many Canadian consumers pledging their support on social media."My heart hurts for the local industry," said software engineer Erum Tanvir in Winnipeg. Last week, she posted a Facebook message to buy Canadian milk.Tanvir says she'll choose Canadian over U.S. dairy products — even if they're more expensive.
