A term for that is underemployment
Statistics Canada collects data about this under the category of "Supplementary unemployment rate": https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=1410007801
Their categories of underemployment include:
- discouraged searchers
- waiting group (recall, replies, long-term future starts)
- involuntary part-timers
- discouraged searchers, waiting group, portion of involuntary part-timers
A lot has happened today after Trump's tirade. Ontario's Premier Doug Ford announced he would be suspending this Ad Campaign after consulting with Canadian Prime Minister Mark Carney:

Manitoba's Premier Wab Kinew has a short video in the same style as the ad where he supports this Ontario Ad Campaign. It's a well done quick response:

I think the Ontario Ad is very well done and I'm glad to see a NDP Premier supporting a Conservative Premier on this and a Conservative Premier publicly supporting a Liberal Prime Minister. Canada is uniting and Trump is unhappy.
