The Canadian Cattle Association is lobbying the federal government to scrap an interim trade deal with the United Kingdom and to start over again.
Its appeal comes while the government is pushing a bill in the House of Commons to accept the interim deal which came after the United Kingdom left the European Union and its trade deal with Canada.
The cattlemen say the United Kingdom is not playing fair on beef trade, using two non-tariff standards to block Canadian beef from its market.
They are the Canadian allowance for farmers to use growth-promoting hormones and beef packers to use an antibacterial wash on carcasses.
Canada insists that science has found both to be safe and effective, but neither the United Kingdom nor the European Union will budge.
Rubbing salt in the wound is the permission for United Kingdom beef to come into the Canadian market.
