Ian’s class were given lacrosse sticks, he brought it home, Brian picked it up to try and never put it down. In 1959 Brian and his brothers traveled from Novar to Huntsville to join the Minor Lacrosse League.

While in Oshawa the Green Gaels won seven Minto Cups (Canadian Junior A Championships) from 1963-1969 of which Brian played on three in 1964-1965-1966.
1967 and 1968 back in Huntsville proved to be stellar for Brian as he was the Junior A League MVP both years.
In 1969 legendary lacrosse great Jack Bionda arrived in Huntsville and Brian moved into the Senior League.
1971 was a memorable year for Brian and fellow team mate Ken Thompson when they got a call from former coach Jim Bishop who was now coaching Senior B in Windsor Ontario. Each game saw the boys hop on a small plane at the Muskoka Airport to fly to Windsor to play. Due to the considerable distance the boys attended no practices, but still managed to win the Presidents Cup (Senior B Canadian Lacrosse Championship).

Brian was inducted into the Canadian Lacrosse Hall of Fame in 1996.
