The championship was officially adopted by Hockey Canada during a summer meeting in 2002.
The first ever Maritime-North Championship was won by the Chebucto Canadians of Nova Scotia in the Spring of 2003. Chebucto defeated the Dieppe/Memramcook Voyageurs of the New Brunswick Junior C Hockey League 4–3 in triple overtime to win the title.
The 2015 tournament in Sherwood, Prince Edward Island marked the first time in tournament history that neither team in the final represented New Brunswick or Nova Scotia. Baffin made the final by upsetting New Brunswick's Western Valley Panthers while PEI's South Side Lynx beat Nova Scotia's Truro Rhinos to reach the championship game. This would mark only the second time a Hockey North team made the final and the first time ever a PEI team had made it. Baffin led 6-1 early in the second, only to have South Side battle back to within one goal. Baffin won the game 6–5 to win Nunavut's first Maritime-Hockey North junior hockey title.
