Canada vs. China: Which Economy has a Larger Impact on the U.S.?

Hey Monkeys,

China may have been getting the most press over the past few weeks, but Canada isn't doing too well either. Here is a quote from the Financial Post:

Canada counts for 19 per cent of total U.S. exports, followed by Mexico at 16 percent, each more than double China's 7 per cent share. And the Canadian dollar is sliding much faster: It has fallen about 12 per cent against the U.S. dollar since the start of the year, while China's yuan has dropped just about 3 per cent.

Since Canada is the largest U.S export market, does Canada's current situation spell more trouble (in the U.S.) than China's decline of late?
