CTV News has declared a Liberal minority win for Canada's 43rd federal election. 

Follow this page all evening for updates from our CTV News team in Ottawa. 

Liberal Karen McCrimmon has won re-election in Kanata-Carleton, beating Conservative rival Justina McCaffrey with more than 42% of the vote.

Longtime Conservative Pierre Poilievre has been re-elected in Carleton, beating out Liberal Chris Rodgers.

Liberal incumbent Catherine McKenna has been re-elected in Ottawa Centre, defeating NDP candidate Emilie Taman. Mckenna was previously elected in 2015, ending a long NDP run in Ottawa Centre, and has been a senior member of the Trudeau cabinet as the minister of environment and climate change.

The riding of Nepean has re-elected Liberal Chandra Arya, beating Conservative Brian St. Louis.

Marie-France Lalonde has won the riding of Orléans, beating out Conservative David Bertschi. The riding had no incumbent after Liberal MP Andrew Leslie announced he would not be running again. Lalonde previously represented Orléans at the provincial level.

The riding of Ottawa West-Nepean has re-elected Liberal incumbent Anita Vandenbeld.

Liberal Greg Fergus has held onto his seat in the riding of Hull-Aylmer, along with Liberal David McGuinty in Ottawa South.

Liberal incumbent Steven MacKinnon has been re-elected in Gatineau. Liberal Mona Fortier has also held onto her seat in Ottawa-Vanier.

CTV's Megan Shaw is in Carleton, where Conservative Pierre Poilievre is seeking re-election. Liberal Chris Rodgers is running against Poilievre for a second time; he lost by less than 2,000 votes in 2015. Liberal leader Justin Trudeau visited the riding several times during the campaign.

As the results start to come in after the polls close at 9:30 p.m., the CTV Ottawa team will be fanning out across the city to gather reaction from candidates and their supporters.

As the results come in across the country, this interactive map will show up-to-the-minute results. You can zoom in and view the map by province, region, and even city-by-city.

With more than 10 per cent of voters undecided, according to the latest Nanos polling, it will be interesting to see how many of those electors show up to the polls today.

Voter turnout from the last few federal elections:

2015: 68.5 per cent

2011: 61.1 per cent

2008: 58.8 per cent

2006: 64.7 per cent

In Orleans, the Liberals are trying to hold on to a riding without an incumbent. Former MP Andrew Leslie announced last spring he wouldn't seek re-election, opening the door for a new Liberal candidate. Marie-France Lalonde, a former provincial cabinet minister, stepped down from her post at Queen's Park to run for the Liberals federally.

The Conservative candidate, David Bertschi, is a lawyer and former Liberal leadership candidate trying to turn the riding blue.

Jacqueline Wiens is running for the New Democrats and Michelle Peterson is the Green Party candidate.

One of the close races we're following is Ottawa-Centre. Liberal candidate Catherine McKenna is looking to hold onto her seat, but is facing competition from NDP candidate Emilie Taman.

"Elections are choices, and I'm certainly hoping that I will earn peoples' vote again," McKenna said Monday morning.

Ottawa-Centre has a long history of electing New Democrats, with the party holding for the riding more than a decade before McKenna won in 2015. It also had the highest voter turnout in the country in 2015, at just over 82 per cent.

Kanata-Carleton is a swing riding to watch, where incumbent Liberal Karen McCrimmon is facing a challenge from Conservative Justina McCaffrey in an area that has historically leaned blue. McCrimmon won the riding by nearly 8,000 votes in 2015.

A reminder on the numbers: a political party needs to win 170 out of 338 seats to secure a majority government in the House of Commons.
