Canada’s Spying

The Toronto Star has an unlinkable but
interesting article
on the high-tech Echelon surveillance system operated by
five nations known as the UKUSA alliance: the United States, Britain, Canada,
Australia and New Zealand. Apparently Canada spied for Thatcher on two of her
cabinet collegues under part of the agreement that allows effectively for
internal spying by a friendly nation within the circle. So who is spying on
Canadians on the request of our government? And for what?
