There's growing concern in the agriculture sector over a potential CP Rail strike. 

Foothills MP John Barlow is the Conservative shadow minister for agriculture and agri-food.

"To do this when we are already in a critical situation within our supply chain I think is extremely tone deaf and there will be zero sympathy for the union of CP Rail so they had better resolve this as soon as possible."

"The implications for agriculture specifically are profound but certainly this will impact important industries that are critical to Canada's economy throughout our country," he says.

He notes we're already feeling the effect of a looming rail strike, as U.S. suppliers are refusing to fill the rail cars because they don't want their cars stranded in Canada in the midst of a strike.
