Stephen Hennigar and Alexa Wray were fishing in the Shubenacadie River Wednesday when they found the discarded wine bottle, containing the letter and a few artifacts, CBC News reported.
The letter, signed by two teens named Jill and Kelly, read: "The year is 2002. It would be cool if someone found this in the year 3002 or something. We hope it'll go very far."
"So we can't let things like this go on any more."
It was accompanied by photos of Jill and Kelly and some friends, and after CBC News first carried the story, Jillian Boyce and Kelly Johnston, both 25, said they were the ones who released the bottle.
"I never really expected anyone to find it," Boyce said.
Johnston said she hasn't seen Boyce "in many, many years."
"It's crazy to think that after all this time a silly letter in a bottle could put us back in touch," she said.
"Oh my god," said Boyce. "How did it not get ruined?"
