It is assumed that the Canadian Government Department will approve genetically modified pigs, the Enviropig, the first transgenic animal created to solve an environmental problem.

University of Guelph, the sole owner and producer of the animals, has successfully produced the Enviropig, using approved containment procedures, thereby abiding by the Canadian Environmental Protection Act.

Environment Canada will announce approval of the strain known as enviropigs, after being approved by Health Canada, before the pigs enter the food market.

The Yorkshire pigs were developed by researchers in Ontario at the University of Guelph, who spliced in genes from mice to decrease the amount of phosphorus produced in the pigs' dung to as less as 30-65%, which has been problematic in surface and groundwater around large livestock operations.

Steven Liss, Associate Vice-President for research at the University of Guelph told that an application had been sent to the U. S. Food and Drug Administration and added that the University of Guelph will continue to breed the animals under strict confinement and control measures.
