I am currently reading the book Studies in Hyperinflation and Stabilization http://www.centerforfinancialstability.org/hyperinflation.php which is a collection of oldish papers examining different hyperinflations which have happened through time. The first lesson they state (page xxii) is that "We, like others, have identified the cause of hyperinflation as the substitution of [money creation] for the tax financing of government expenditures" (i.e. when instead of raising taxes to finance government spending the central bank just prints).
Now not wanting to dive into politics too much, but I think its safe to say in the US/Canada at this point there is very little appetite for the type of tax increases that would be necessary to fund the type of deficits of the past year, and are expected for the coming years. As well, the politically easy type of taxes that may be implemented (i.e. wealth taxes, tax on high income earners) will not end up generating that much revenue. With this in mind it is very easy to imagine a high inflation scenario (maybe not hyperinflation, but higher than most of us would have experienced in our lifetimes) over the next decade or so, the government keeps printing because it is the easy thing to do.
