O'Connor was originally acquired in a trade with the Pittsburgh Penguins at the beginning of February and has since scored two goals and racked up four assists in four games.
"Drew has really made a good first impression since joining our team from Pittsburgh at the beginning of the month," said Canucks General Manager Patrik Allvin. "We like his size, speed and ability to get in on the forecheck and hound pucks. Our staff also feel confident that they can help Drew take his game to another level and we are excited to see what the future holds for him with the Vancouver Canucks."
The 26-year-old from New Jersey was previously on a two-year deal worth $1.825 million that had him making $925,000. He was set to be a free agent after this season before signing the extension.
Between the Penguins and Canucks, O'Connor has eight goals and 10 assists in 57 games.
He made his rookie debut for the Penguins during the 2020-2021 season but didn't have a breakout year until 2023-2024 when he put up a career-high 16 goals and 17 assists in 79 games.
