Bottcher advanced to the championship game with a 9-3 win in eight ends over Sweden in the Page 1 versus 2 playoff game.
Canada and Sweden will stage a rematch for the gold medal. The Swedes defeated Norway 8-4 in the semifinal contest later Saturday.
Norway had advanced to the semifinal game after edging Scotland 9-8 in the Page 3 versus 4 playoff contest.
Bottcher said it really didn't matter to him which team he faced in the final.
"We had close games against both these teams in the round robin," Bottcher said. "So we just need to play good and if that happens, we'll have as good a chance as any."
Canada finished the round robin atop the overall standings with an 8-1 record and hasn't won the world junior men's title since 2003.
Bottcher led 3-2 when he took control of the match in the fifth, scoring three. After Sweden scored one to make it 6-3, Bottcher clinched the victory with three in the seventh.
Swedish skip Rasmus Wrana offered to shake hands before Bottcher played his final rock of the end, however event officials said eight complete ends had to be played. So the two sides complied by blanking the end before shaking hands.
"The team came out and played great in front of me, and that's a great game for us moving into the final," he said. "I felt like at the end of the week and the round-robin we were building, and then today we came out strong.
"So we just need to come out (Sunday) with the same team and hopefully we can win it."
Bottcher said both sides needed clarification about the tournament rules following the seventh end.
"There was just confusion about whether or not they were allowed to quit," he said. "When we were told we had to play we, we just decided to throw them all through, because they were shaking hands after it anyway.
"It's just a tough rule to enforce — it's annoying more than anything else."
Jocelyn Peterman of Red Deer, Alta., was eliminated from the women's draw Friday with an 11-10 loss to Russia in a tie-breaker game.
