Canadians Continue to Absorb Assaults On Economy.  -dh CBC. Postcards usually tell stories or show a vacation spot, but at a farmers market on Saturday they warned against a pipeline planned near Winnipeg's water supply. About eight volunteers with the Manitoba Energy Justice Coalition handed out postcards against pipelines at the St. Norbert Farmer's Market with a message to the mayor. "I urge you to protect Winnipeg's drinking water and the Shoal Lake Watershed by rejecting TransCanada's Energy East pipeline," the postcard read.
