When election results start coming in on October 21, it will be Newfoundland and Labrador that tells us first if the winds of change are blowing. In 2015, the Liberals swept Atlantic Canada, taking every seat, including all seven in Newfoundland and Labrador. And it's still possible they do it again—but that's far from certain.

So what were Newfoundlanders promised in 2015, and have the Liberals delivered? What matters most to voters out east, and what unique challenges are they dealing with? And if we're looking for signs on election night that Canada will have a new government, which ridings should we be watching?
