This concludes our live coverage of Canada's 43rd national election.

Justin Trudeau's Liberals have retained power, with a projected 156 seats. This is short of an overall majority, but more than the estimated 122 seats won by the Conservatives opposition.

The prime minister will thus lead a minority government in his second term

Wexit has been trending on Twitter. So what is it?

Wexit is the name of a campaign to see the western province of Alberta break away from Canada to form its own nation - perhaps with another western province. The idea has gained new momentum as relations between conservative Alberta and the rest of the country have deteriorated.

If current election projections hold, there will be no Liberal districts in Alberta or Saskatchewan, CBC reports.

Conservatives have claimed the overwhelming majority of seats in the two provinces.

Green Party leader Elizabeth May gave her speech last - typically, the winning party goes last, but tonight, Trudeau, Scheer and Singh all spoke at the same time.

May said the election had been a success for the party, which won its first seat outside British Columbia in New Brunswick.

May said there would be "crispy toes" as she held feet to the fire in Parliament.

Liberals have won 145 seats and are leading in 11 more, national broadcaster CBC reports. Conservatives have been elected to 119 seats and are leading in three more. The New Democratic Party has 23 seats so far.

Canadians elected a Liberal minority government with a projected 155 seats out of 338. The Conservatives got 122, according to the CBC election tracker.

The Conservatives were just ahead of the Liberals in terms of the popular vote - 34.5% to 33%.

“Let’s remember this feeling, coming close but falling just short,” Conservative leader Andrew Scheer said in Regina, Saskatchewan.

The party made some gains, sweeping the prairies, and picking up seats in New Brunswick, Ontario and British Columbia. That leaves the Conservatives with 24 more seats now than they had in 2015.

That, Scheer said, gives the party “hope” that it can regain power in the future.

Conservative leader Andrew Scheer told supporters in Regina, Saskatchewan, that he was proud despite the party's losses.

"Regardless of how you cast your ballot, ours is a team that will fight for all Canadians," Trudeau said.

On a night when the separatist Bloc Quebecois tripled its representation, Trudeau promised the province's voters that their voice would be heard in the capital Ottowa.

"Let us all work hard to bring our country together," he said, referencing voters in the Conservative-majority provinces of Alberta and Saskatchewan.

Three party leaders took the stage to deliver speeches at the same time.

While NDP leader spoke in British Columbia, Conservative Andrew Scheer thanked supporters in Regina, Saskatchewan.

A joyful Trudeau addressed fellow Liberals in Montreal moments later.

"I have heard you, my friends. You are sending our Liberal team back to work, back to Ottowa with a clear mandate," he said.

"We will make life more affordable. We will continue to fight climate change, we will get guns off our streets and we will keep investing in Canadians."

"You did it my friends, congratulations," the prime minister said.

Speaking at his headquarters in Burnaby, British Columbia, New Democratic Party (NDP) leader Jagmeet Singh told supporters: "We are going to make sure the energy we built over the campaign... continues so we can play a constructive and positive role in the parliament Canadians have chosen."

Singh in particular emphasised a need for more focus on indigenous issues.

He also congratulated Prime Minister Justin Trudeau. The NDP came fourth with a projected 25 seats.

Jody Wilson-Raybould, an indigenous politician, has won her Vancouver district as an independent.

She was booted from the Liberal party by Justin Trudeau amid the SNC-Lavalin affair.

The scandal drew attention to Trudeau's perceived weaknesses - his ties to corporate interests, his alleged shortcomings on feminist and First Nation issues and heavy-handedness as a party leader.

However, Jane Philpott, who left the Liberal party in support of Wilson-Raybould, has lost her district.

Bloc Québecois leader Yves-François Blanchet told cheering supporters in Montreal: "We have come a long way and we will go even further."

The separatist Bloc has won at least 30 seats, according to CBC, which would be more than triple what they had prior to the election.

Blanchet added that his party would not join any governing coalition in the federal parliament.

Liberal Amarjeet Sohi, Minister of Natural Resources, has lost his seat in Alberta to Conservative Tim Uppal.

He had defeated Uppal in a narrow race in 2015.

Alberta is a majority Conservative province.

Local media report that Trudeau's Liberals and Scheer's Conservatives both have about 34% of the popular vote.

In 1972, Pierre Trudeau, Justin Trudeau's father, won his second term as prime minister - by a slim margin that invites comparisons to 2019.

The so-called Trudeaumania that had followed Pierre's first term had faded after his marriage to Margaret Sinclair in 1971. During the 1972 election, his Liberal party won 109 seats, while the Conservatives won 107.

In 2015, Justin won his first term in a similar sweep by Liberals - only for that support to fade upon re-election.

As of 23:30 EST (03:30 GMT), the Liberals have won 117 seats while the Conservatives hold 105.

The mood is joyful if not jubilant in the Liberal election headquarters in Montreal, where supporters are cheering results showing Liberal wins as they come up on the big television screens.

They may not have their majority but the Liberals are on track to win the most seats - and projections currently suggest it’s not as close a race between the Liberals and Conservatives as some polls had suggested.

As one young supporter, Adam Steiner, 18, told the BBC, a minority scenario is “not great” but at least the party “kept the Conservatives out of power”.

What does this mean for Justin Trudeau?

If he does form a minority government it’ll mean compromises, since his Liberals will need outside support to hold on to power.
