I recall no such thing and see nothing in the historical record to substantiate your claim. It is a fact that Trudeau was greatly concerned with environmental issues and negotiated the Great Lakes treaty because so much of the pollution came from the states and found its way into Canadian waters and lands (I well remember my Irish kid brother telling me when he traveled up there a tour guide made it a point of telling the tourists about that and making them feel guilty about it). Here's a blurb on the subject:
''Bukro’s coverage of the Great Lakes, as well as some hard-hitting editorials published by the conservative Tribune, turned up the heat on the Nixon administration to do something about the spiraling concerns people had about the environment. In April 1972, Nixon and Canadian Prime Minister Pierre Trudeau signed the landmark Great Lakes Water Quality Agreement, a pact in which the United States and Canada set cleanup goals for the lakes. Six months later, in October of 1972, Nixon—who created the Environmental Protection Agency—signed America’s Clean Water Act. That’s the law for which many of today’s sewage and industrial discharge limits are set. Both actions resulted in enormous costs and subjected Nixon to pressure from industry groups.''

While right wingers did not like it, liberals and moderates who were the majority at that time GREATLY appreciated and viewed Nixon as a great hero for his reforms. But it was Trudeau who exerted the greatest influence on him and that's why we had these changes. Again,
NOTHING about this was anti-American at all.
