Each year since 2004, the Bank of Canada has surveyed banks that are active in the Canadian-dollar foreign exchange market. Survey questions focus on the foreign exchange hedging activities of their Canadian corporate customers in order to better understand the degree and manner to which hedging activities are evolving in corporate Canada (whether through reliance on natural hedges or through the use of financial market instruments) and to gauge the extent to which the banks' corporate client base relies on such strategies to manage the effects of changes in the level of the Canadian dollar.
