Bank of Canada have restructured the way they offer Exchange rates (New url and format). The impact of this is that the exchange rates module is no longer able to download exchange rates from Bank of Canada.
We will include the updated url and format in B1UP 2017.05 (May release) and recommend switching to an alternative provider until B1UP 2017.05 is released.
B1UP 2017.05 is scheduled for release on the 8th of May.
