With exit polls not expected for another few hours, it is worth visiting one of the possible outcomes.
Canadians voted Monday in what pundits called one of the country's closest elections ever, leaving the future of Prime Minister Justin Trudeau in doubt.
Neither of the two parties is forecast to garner enough support to secure an absolute majority of seats in Parliament.
Four in ten (36 percent) Canadians said that, ultimately, they didn't "really like any" of their options in the 2019 election.
It was a stunning upset for the party, which leapfrogged from third place to defeat the Conservatives, who had been in power for almost a decade.
The Conservatives, NDP and Greens did not immediately respond to requests for comment.
At final campaign stops in westernmost British Columbia on Sunday, former golden boy Trudeau made an emotional appeal to voters to enable him to build on the achievements of his first term.
From when Liberal Leader Justin Trudeau fired the starting gun on the campaign on September 11, voters have heard a mix of policy promises and warnings about dire consequences from each party leader if he or she doesn't come out on top.
Trudeau, the son of former Canadian Prime Minister Pierre Trudeau, has also had to overcome a sense of fatigue with his government.
The 40-day campaign, described by Trudeau as "one of the dirtiest, nastiest" in Canadian history, has been "a desert from a public-policy point of view", according to pollster Nik Nanos of Nanos Research.
The other leaders also sought to portray a Tory government as one that would cut services for Canadians after Scheer promised to balance the budget in five years, and he faced questions about his US citizenship and claims to have been an insurance broker.
"Scheer has been hostage to the message", Nanos said.
"He voted against major pipeline projects that would get Saskatchewan resources to other markets".
The NDP leader was cheered by volunteers and supporters as he visited a campaign office in Burnaby, where he thanked those who helped over the past month and a half before reflecting on the party's campaign.
"We were able to say to the people: we will govern, we are ready to govern, we have a plan, a definitive plan", he said earlier this week after Scheer's final rally in the province.
On the eve of the election, an average of polling suggested that despite a hard campaign, Trudeau could narrowly cling onto power-albeit far less of it.
Bloc Quebecois Leader Yves-Francois Blanchet has overseen a surge in support in la belle province after his party was largely left for dead after abysmal results in 2011 and 2015 followed by years of infighting.
Blanchet said separatism wasn't a priority for his party, nor was a referendum on the matter imminent.
Elizabeth May is hoping her Green party can capitalize on its recent success in provincial votes and translate that to more seats in the House of Commons.
"That money belongs to you, not to them", Scheer said.
"I didn't think that this election would be so marred by dishonesty", she said.
And Maxime Bernier, who has spent much of the campaign trying to protect his own seat in Quebec, will find out whether his upstart People's Party of Canada is a movement or a footnote.
In most of Ontario, the polls will be open Monday from 9:30 a.m. -9:30 p.m.
A CBC reporter who voted at the polling station said workers had set up makeshift lighting at all voting booths, and election workers were using flashlights to check voter lists.
Voter turnout in the last election stood at 68.5 per cent, which was the highest since 1993. That marked a 29 per cent increase over 2015.
