Selected by Vancouver Canucks round 5 #67 overall 1972 NHL Amateur Draft.
He gained the respect of those on his team and other opponents as a strong defensive player who took care of business in his own zone.
He did dress for 15 games with the Canucks that fall of '72 but the majority of his season was spent in the minors with the Seattle Totems.
In the summer of 1974 Bolonchuk was claimed by the Washington Capitals in the Expansion Draft. But in his first three years in the Capitals' organization he was called up for only ten games. He finally had a breakthrough season in 1977-78 when he suited up for 49 games with Washington but still seemed to be a fringe player at best. Given the fact the Capitals were still one of the worst teams in the NHL at the time, it was clear if Bolonchuk couldn't make it in Washington he was not going to be picked up by any other team.
Bolonchuk played another two years in the minors but was never called back to the NHL. He retired after the 1979-80 season at the age of 28.
