OHA Senior A Hockey League The OHA Senior A Hockey League was a top tier Canadian Senior ice hockey league in Ontario from 1975 until 1987 . The league was sanctioned by the Ontario Hockey Association and the Canadian Amateur Hockey Association and competed for the Allan Cup . History . In 1972 , the Western Ontario Senior B Hockey League was formed . Members of this league included the Bothwell Barons , Durham Huskies , Lucan - Ilderton Jets , London Kings , Preston Jesters , and Stratford Perths . In 1973 , the league changed its name to the Continental Senior B Hockey League . In 1975 , two season later the league became the Continental Senior A Hockey League , making the league eligible for the Allan Cup and parallel with the traditional OHA Senior A Hockey League . The Chatham Maroons , New Hamburg Screaming Eagles , Petrolia Squires , and Port Stanley Dynamiters joined the league . After the 1978 - 79 season , the original OHA Senior A Hockey League folded and its top team , the Cambridge Hornets , salvaged itself by joining the Continental Senior league . The Continental league stood alone as the top league in Ontario . A season later , the league was rebranded the OHA Senior A Hockey League . In 1983 , the OHA Senior A Hockey League absorbed the Major Intermediate A Hockey League , nearly doubling the league ' s size . In 1986 , the league shrunk down to three teams , added Hockey Northwestern Ontario ' s Thunder Bay Twins as a fourth team , and then folded after the season . The OHA Senior A league spawned four Allan Cup champions from 1979 until 1987 . The final season was finished off in style , as the league champion Brantford Motts Clamatos went on to win the Allan Cup as National Senior " A " Champions . The league was replaced in 1990 by the Southwestern Senior A Hockey League which is now known as Major League Hockey . Allan Cup s . Champions Finalists Hardy Cup s . Champions Key rivalries . Durham vs . Lucan - Ilderton Prior to the creation of the Western Senior B league , the Durham Huskies and Lucan - Ilderton Jets had a healthy rivalry running in the various Ontario Hockey Association Intermediate leagues . In 1971 - 72 , the Jets pulled out of the Southern Counties Intermediate B league in favour of running an independent schedule . Durham had won the Provincial Intermediate B championship in 1968 and 1969 , as well as a local title in 1971 . The Jets won the Provincial title in 1970 and the local playoff title in 1972 . The Jets had made wind about challenging for the Allan Cup in 1972 , but their bravado was squashed by the OHA Champion Napanee Comets . The Western Senior B league was virtually built around the Huskies and Jets and the two teams dominated the first four years of its existence . The one common denominator between the two teams was their need to squash the Stratford Perths in the league final each year . In 1973 , the Jets won the first ever league title by defeating Stratford 4 - games - to - none . A year later , the league became the Centinental Senior B league and Huskies won the league ' s first title under that new name 4 - games - to - 2 against Stratford . In 1975 , the Lucan - Ilderton Jets won again by defeating Stratford 4 - games - to - 1 . After this , the OHA allowed the Jets to challenge for an Allan Cup spot , but they were squashed by the Barrie Flyers 4 - games - to - none . The Huskies got the last laugh in the battle . In 1975 , the league was promoted to Senior " A " and the Huskies won the league ' s first ever championship at that level . They suffered the same fate as the 1975 Jets in the OHA final , losing to Barrie 4 - games - to - none . Cambridge vs . Petrolia The Petrolia Squires joined the Continental Senior A Hockey League in 1976 . In 1979 , after two years in the league , the Squires won the Continental Senior " A " title , the OHA Sr . " A " title by beating the Thunder Bay Twins 4 - games - to - 2 , and eventually the Allan Cup . This was the first of four Allan Cups the league would celebrate over the last nine seasons . In 1979 , the other Senior " A " league folded and the Cambridge Hornets jumped ship . In their first season in the league together , the Hornets would challenge the Squires in the league final and defeat them in a full seven game battle , 4 - games - to - 3 . The Hornets lost the Allan Cup final . The next year , the two teams met in the final and the Squires won 4 - games - to - 1 and went on to win their second Allan Cup . In 1982 , they met again in the final and the Squires came out on top 4 - games - to - 3 . The Squires lost the Allan Cup final . Then in 1983 , the Cambridge Hornets took control , winning the final against Petrolia 4 - games - to - 3 and won their first Allan Cup since 1971 . The fifth and final chapter took place in 1984 as the Cambridge Hornets defeated the Petrolia Squires in the league final 4 - games - to - 2 , but lost in the Allan Cup final . Overall , the Cambridge Hornets appear to have come out on top in this rivalry winning three out of five league championships in a five year span and winning an Allan Cup , but it is possible that they " won the battle , but lost the war " . The Petrolia Squires , who won two of the five years and an Allan Cup have an edge in history . The Hornets folded in 1987 and reformed in 1999 and again folded due to controversy in Major League Hockey in 2006 , while the Squires currently hold the title as the longest running current Ontario Hockey Association Senior team and are charter members of Major League Hockey . In terms of longevity , the Squires came out on top . Dundas vs . Motts Clamatos The Dundas Merchants jumped to the OHA Senior " A " league in 1980 from the Niagara & District Intermediate A Hockey League . Until 1984 , the league was completely and utterly dominated by Cambridge and Petrolia . In 1981 , the team changed their name to the Dundas - Hamilton Tigers . In 1983 , the Rockton Real McCoys of the Southern Intermediate B league moved to become the Flamborough Real McCoys and joined the OHA Senior " A " league . A year later Real McCoy sold the team to Motts and the team became the Flamborough Motts Clamatos . After five seasons of domination , in 1984 the Mott Clamatos and the Tigers took Petrolia and Cambridge ' s spot in the league final . Dundas defeated Flamborough 4 - games - to - 2 . After the season , Dundas was bought by the same company that sold Flamborough to Motts and became the Dundas Real McCoys . In 1986 , Dundas and Flamborough met again in the league final , with the Motts Clamatos sweeping the series 4 - games - to - none . After the season , the league dropped from seven teams to three and were forced to bring in the Thunder Bay Twins as a fourth member . Motts then moved their team from Flamborough to become the Brantford Motts Clamatos . The 1986 - 87 season finished with Brantford far ahead in first , Dundas ahead of Thunder Bay in second by a tie breaker , and Cambridge close but in fourth . Brantford met Dundas for the third straight year in the league final and defeated them , going the distance , 4 - games - to - 3 . Brantford went on to win the Allan Cup that year , only to have their sponsor back out and the team fold at the end of the season . The folding of Dundas and Brantford at the end of the season started a chain reaction of events in Ontario hockey . It began with a few teams folding , and ended with the top tier of both Senior and Junior hockey , the Ontario Provincial Junior A Hockey League , going completely out of business .
