USD/CAD This is the most traded currency combination, the USA is Canada’s biggest trading partner comprising of 66% of Canada’s overall trade. EUR/CAD: The European Union as a group is Canada’s second largest trading partner, as all transactions are in Euros and therefore when all the volumes are added, the total exceeds the next biggest partner, China. CNY/CAD Although China is Canada’s third largest trading partner, a lot of transactions are paid in USD at this time. Eventually all trading with China will be in the form of CNY/CAD. GBP/CAD Britain was at one time Canada’s second largest trading partner, and in terms of currency exchange it is now third, but that will change when China enforces its rules that at all imports and exports are priced against CNY.
