He earned 14 points in those nine games and the Toronto Maple Leafs would draft Berehowsky with their first round draft pick in the 1990 NHL Entry Draft. Berehowsky split the 1990–91 season between the Frontenacs and the North Bay Centennials before earning a late season call-up to the Leafs. He returned to North Bay for the 1991–92 season, recording 82 points in 62 games, helping the Centennials to the OHL finals, tallying 31 points in 21 post-season games.

Berehowsky appeared in 25 games with the Maple Leafs in 1994–95. On April 7, 1995, the team traded him to the Pittsburgh Penguins for Grant Jennings.
