a) Consumers would have a negative impact in Canada since they might have to spend higher equivalent CAD for the US imports than earlier. Also domestic producers will prefer to export since they have better margins because of CAD depreciation which will cause local prices for goods exported to increase in Canada.
b) Canadian Exporters would have benefitted because of currency depreciation since that will make their products more competitive in the US markets which can lead to higher demand or they can have higher margins for same demand.
