Canada probes use of toxic chemical

Agent Orange is a chemical that was used extensively by the United States during the Vietnam War to destroy vast areas of jungle.

It can result in a number of serious side effects for those exposed to the chemical for prolonged periods of time; this includes birth defects and even death.

Now, it has been revealed that Agent Orange was used on vegetation in Canada's Ontario province from the 1950s to the 1970s.

This has prompted the Canadian government to open an investigation into the use of the chemical.
