I'll be very brief.
In any economy globally consumers benefit from lower energy prices, so there is the next step: do they spend the money they save, or do they save the money they save? That determines how it affects the economy, which makes it complicated.
In Canada it is doubly complicated, because some people lose their jobs—they're no longer on a project in Alberta or what have you—and their consumption goes down.
So we have to analyze the total effect, which is what is so complex about that question.
