Trudeau, party leaders congratulate president-elect Joe Biden on U.S. election victory

Prime Minister Justin Trudeau congratulated Democrat Joe Biden on his election as the next president of the United States, saying he looked forward to building on the "extraordinary" relationship shared by Canada and the U.S.

"On behalf of the Government of Canada, I congratulate Joe Biden and Kamala Harris on their election as the next President and Vice-President of the United States of America," read a statement issued by Trudeau Saturday.

"Canada and the United States enjoy an extraordinary relationship one that is unique on the world stage. Our shared geography, common interests, deep personal connections, and strong economic ties make us close friends, partners, and allies.

"We will further build on this foundation as we continue to keep our people safe and healthy from the impacts of the global COVID-19 pandemic, and work to advance peace and inclusion, economic prosperity, and climate action around the world."

The prime minister added that he was looking forward to working with Biden, Harris, their administrationand the U.S. Congress to "tackle the world's greatest challenges together."

Biden defeated Donald Trump to become the 46th president of the United States after securing enough electoral college votes on Saturday, according to U.S. networks.

Biden's victory came after more than three days of uncertainty as election officials sorted through a surge of mail-in votes that delayed the processing of some ballots. Biden crossed the threshold of 270 electoral college votes with a win in his home state of Pennsylvania, though Trump is contesting some states' results.

Echoing Trudeau's message, Deputy Prime Minister Chrystia Freeland said Canada would work "shoulder to shoulder" with Biden as the two nations "confront the greatest challenges of our time, at home and abroad."

Joe Biden's successful bid for the U.S. presidency has consequences for Canada. Federal and provincial leaders are reacting to his victory.

Party leaders weigh in

Federal Conservative Leader Erin O'Toole took to Twitter to convey his congratulations, also nodding to the historic relationship between the two countries.

In issuing his remarks, NDP Leader Jagmeet Singhfocused on the end of Donald Trump's presidency, quotingformer NDP leader Jack Layton.

While both Trudeau and O'Toole vowed to work with Trump should he be re-elected, both Singh and Bloc Leader Yves-Franois Blanchet have previously expressed their desire to see Trump ousted from the White House.

In a separate tweet, Singh congratulated vice-president elect Kamala Harris on her achievement in becoming the first woman and person of colour to hold that title. The California senator will be the first Black woman and person of South Asian descent elected to the vice-presidency.

The Green Party'sAnnamie Paul several weeks after her own historic win as first Black permanent leader of a federal political party in Canada also congratulated Harris on becomingthe highest-ranking woman ever to serve in U.S. government.

"The election of Joe Biden and Kamala Harris is an opportunity to usher in a new chapter in the vital U.S.-Canada relationship," she said in a statement, saying she hoped to see renewed commitments to climate change and human rights.

Freeland offered her own praise to Harris, calling her victory an inspiration to women, girls and people of colour across North America.

"I look forward to working withyou to help both our countries crush this global pandemic andto crack more glass ceilings along the way," she said on Twitter.

Kirsten Hillman, Canada's ambassador to the U.S., said she welcomed working with the Biden administration on the "many issues of mutual interest we share."

Hillman told CBC News last week thather team wasn't concerned about disruptions to Canada's economy should the results of the race be contested.

Trump has refusedto concede the election and hasthreatenedfurther legal action on ballot counting.
