The Toronto Star reports that a free(er) trade agreement between Canada and the EU is threatened because of Canada's so-called "investor protections" .
"Europeans are growing increasingly wary of trade deals that allow multinational corporations to challenge government rulings before special international tribunals."
What it boils down to is that multinational corporations can challenge, and win against a nation's legislation; you have pollution control laws? Hah! We shit on your pollution control laws! Germany is refusing to sign on, and ALL member states have to sign on before the agreement is implemented.
This could also jeopardize EU and US trade agreements, because the US has similar investor protections in place.
