U.S. election day: What you need to know and how to find results

One of the most divisive races for the White House in recent memory will come to an end on Tuesday as Americans head to the polls, tasked with choosing between two candidates who have each framed the election as fight for the nation's character, democracy and security.

Unlike Canadians, Americans vote directly for who they want to see as president — their choices this year being Democratic nominee Kamala Harris, Republican nominee Donald Trump or a third-party candidate.

Poll opening times vary by state, and even by county, but generally will open first on the East Coast at 6 a.m. ET, while the last poll closes in Alaska at 8 p.m. local time (1 a.m. ET).

Voters had returned more than 80.5 million advance ballots as of Monday.

Harris, 60, said she had intended to vote early to show voters the different options available. Her running mate, Minnesota Gov. Tim Walz, did the same, casting his ballot last week in his home state. President Joe Biden also voted early in his home state of Delaware.

Trump, 78, had previously said he would vote before election day, but is now expected to vote on Tuesday.

Harris planned to spend Tuesday doing radio interviews in all seven battleground states to make sure those final voters "who are on their way to work, on their way home, taking a lunch break — understand the stakes," according to campaign communications director Michael Tyler.

She is expected to make the final argument of her campaign in Washington at the same spot where Trump spoke to supporters before they attacked the U.S. Capitol to block the certification of Biden's electoral victory on Jan. 6, 2021. Harris spoke at the same site last week. 

In turn, Trump will make his final remarks at his Mar-a-Lago estate in Florida. An adviser characterized the speech as a "prebuttal" to Harris's address in the capital.

As usual, each candidate will need 270 electoral votes to win the White House.

In the past, the results have been obvious within a matter of hours on election night. If the presidential race is extremely close and mail-in ballots become a deciding factor, there will be no clear winner on Tuesday night.

The next U.S. president will be consequential for Canada, too: The countries are top allies, side-by-side on the world stage, and one another's largest customers with billions of yearly dollars in trade.

At his own event on the eve of the election on Monday, Walz said voters' choice will have implications far beyond the next presidential term.

"The thing is upon us now, folks," Walz said at a rally in La Crosse, Wis. "I know there is a lot of anxiety, but the decisions that are made over the next 24-36 hours when those polls close, will shape not just the next four years, they will shape the coming generations."
