Possibly founded in 1969, the NBJHL was the premier Jr. A league of the province of New Brunswick. In 1970, the league was relegated to Tier II Junior A and competition for the Centennial Cup. In 1982-83, the league was in direct competition for fans with the American Hockey League, who put two of their Semi-Professional teams in the NBJHL's Jr. A markets. In 1983, the Fredericton Red Wings folded, leaving the Moncton Hawks as the only strong team in the league. Instead of continuing on in the depleted NBJHL, the Hawks elected to move to Nova Scotia's Jr. A league, the Metro Valley Junior Hockey League, leaving the NBJHL to fold.
