There is no issue that some industries in Canada have benefited enormously from a weak Can/US dollar exchange over the past few years. Tech is an industry that immediately comes to mind as a less productive workforce (vs the US) has managed to expand based on the prospect of 'cheap' labour and revenues domiciled in USD. I know of many tech CEOs who are extremely nervous that they are seeing rapidly declining local currency revenue at a time when a housing crisis and rising food costs are forcing workers to demand higher wages.
