U.S. says Canada relinquishing sovereignty with No to missile shield

Canada's announcement that it won't join the U.S. missile shield provoked an immediate warning that it has relinquished sovereignty over its airspace.
From now on, the U.S. government will control any decision to fire at incoming missiles over Canadian territory, declared the top U.S. envoy to Canada.
"We will deploy. We will defend North America," said Paul Cellucci, the U.S. ambassador to Canada.
"We simply cannot understand why Canada would in effect give up its sovereignty - its seat at the table - to decide what to do about a missile that might be coming towards Canada."
The response came just moments after Prime Minister Paul Martin ended months of ambiguity Thursday by announcing that he would not sign on to the controversial missile-defence program.
