A low CAD is good for me, since I mostly work online and tend to be commissioned by American or European clients.
Probably good for our manufacturing and resource sectors too, by making exports more competitive. While imports are less competitive, which will encourage more people to spend their money in Canada, rather than leaking money from our economy on cross border shopping trips or hiring American consulting firms.
It all sorts itself out in the end.
(As for national debt, if we just actually taxed the rich we'd fix that fairly quickly. Something like 200 billionaires are sitting on enough wealth to erase a major chunk of it while still leaving them with more money than they could spend in a lifetime... just put up a tax on taking money out of the country first.)
