Canada export depends on how low the CAD $ is vs US funds. Logically it works both ways - How Trudeau works to drop Canadian Dollars - or how Trump works on economy. Right now, the US funds is making exports working just fine. Canada is suffering from low metal pricing (mining), low oil prices and ridiculous paper pricing coming from China. These are our natural resources that are hitting us hard. We are in a cycle that seems endless. The terrible part is having both major markets down simultaneously - Mining and Oil, whereas Pulp and Paper reached it's rock bottom. It can't go any lower.
Exports of machinery and others are doing OK. Just like our hobby market and tourists is on the rise. Low currency is good for attracting foreign money but not good for local Canadians. So, IMHO exports depends on competitive currencies.
My concern is Trump putting a tariff on foreign made goods making it too expensive to buy anything but American made. he always has preached to buy American. The new Canadian carbon tax will also give the US an advantage over Canada. Our low dollar will not offset those differences.
