Inter Miami forward Lionel Messi led Argentina to the Copa America final with a 2-0 win over Canada.
The 37-year-old doubled Argentina's lead six minutes into the second half, deflecting a shot from Chelsea midfielder Enzo Fernandez past Canada goalkeeper Maxime Crepeau.
Manchester City striker Julian Alvarez opened the scoring, converting from close range after receiving a pass from Atletico Madrid's Rodrigo de Paul.
This marks the sixth time in the last eight editions that Argentina, 15-time Copa America winners, have reached the final.
The final, against either Uruguay or Colombia, will be Angel di Maria's last appearance for Argentina before his international retirement, and there are also doubts about Messi's long-term future.
"Let's enjoy what we are experiencing as a national team, as a group. It is not easy to be in a final again, to compete again to be champions," Messi told TyC Sports.
"I'm living it as I have been living everything lately - enjoying it very much and being aware, as it happens to Fideo (Di Maria) and Ota (Nicolas Otamendi), that these are the last battles."
Argentina coach Lionel Scaloni says he will work to "convince" Di Maria and Messi to continue their international careers.
"For Leo (Messi), it's similar to Angel," said Scaloni.
"We have to let him be, and we will never be the ones to close the door. He can be with our team for as long as he wants to be. And if he wants to retire but still come and hang around, it would be great."
Nashville winger Jacob Shaffelburg squandered Canada's best chances early in the match.
Canada, ranked 48th in the world, were knocked off their stride by Alvarez's goal, allowing Argentina to take control.
Lille striker Jonathan David had Canada's best chance in first-half stoppage time, but his shot was fired straight at Aston Villa goalkeeper Emiliano Martinez.
Despite the defeat, Canada exceeded expectations in their inaugural Copa America appearance.
Jesse Marsch's side, co-hosts of the 2026 World Cup alongside Mexico and the USA, will face the loser of the other semi-final in a third-place play-off on Sunday.
"I told the team afterward that I know they're very disappointed, but I'm very proud of them," said Marsch.
"We've put together some incredible performances, just starting our process."
Marsch added that it's important for Canada to "expand" their "player pool" in the coming years.
The semi-final between Uruguay and Colombia takes place on Thursday, 11 July at 01:00 BST, and the Copa America final is on Monday, 15 July (01:00).
