very under-priced, with ridiculously cheap prices to park for entire days. I'd even say it's even common in a majority of Canadian towns and small cities. Even in just outside of Toronto free street parking is widely available in "downtown" areas after 6pm and sometimes all weekend. Similar models are common all over the states, even in major US cities.
Good episode from a couple years ago about the topic on the podcast The War on Cars (name inspired by Rob Ford), discussing the effects of free parking with the late Donald Shoup, urban planning professor and author of The High Cost of Free Parking. Good discussion and offers an interesting perspective:
