Yes, there is and I think it's older than the NFL. I'll check.

CFL founded as the Canadian Rugby Football Union in 1884. The CRFU was reorganized as the Canadian Rugby Union (CRU) in 1892, and served as an umbrella organization that several leagues were part of. The Grey Cup was donated by Governor General Earl Grey in 1909 to the team winning the Senior Amateur Football Championship of Canada. By that time, the sport as played in Canada had diverged markedly different from its rugby origins. From the 1930s to the 1950s the two senior leagues of the CRU, the Inter provincial Rugby Union (IRFU) and Western Inter provincial Football Union (WIFU) gradually evolved from amateur to professional leagues, and amateur teams such as those in the Ontario Rugby Football Union (ORFU) were no longer competitive in their challenges for the Cup. The ORFU withdrew from Grey Cup competition in 1954, heralding the start of the modern era of professional Canadian football, in which the Grey Cup has been exclusively contested by professional teams (Since 1965, Canada's top amateur teams, competing in Canadian Inter university Sport (CIS), have contested the Vanier Cup).

In 1956, the IRFU and WIFU formed a new umbrella organization, the Canadian Football Council (CFC), and in 1958, the CFC left the CRU, becoming the Canadian Football League (The CRU remained the governing body for amateur play in Canada, eventually adopting the name Football Canada). Initially, there was no inter-divisional play between eastern (IRFU) and western (WIFU) teams except at the Grey Cup final. Limited interlocking play was introduced in 1961 and by 1981 there was a full interlocking schedule of 16 games per season. The separate histories of the IRFU and the WIFU accounted for the fact that two teams had basically the same nickname: the IRFU's Ottawa Rough Riders were often called the "Eastern Riders", while the WIFU's Saskatchewan Roughriders were called the "Western Riders" or "Green Riders". Other team nicknames had unusual yet traditional origins: with rowing a national craze in the late 1800s, the Argonaut Rowing Club of Toronto formed a rugby team for its members' off-season participation; the club nickname Toronto Argonauts remains to this day, and after World War II, the two teams in Hamilton—the Tigers and the Wildcats—merged both their organizations and their nicknames, forming the Hamilton Tiger-Cats. After the admission of the expansion British Columbia Lions in 1954, the league remained stable with nine franchises (BC Lions, Calgary Stampeders, Edmonton Eskimos, Saskatchewan Roughriders, Winnipeg Blue Bombers, Hamilton Tiger-Cats, Toronto Argonauts, Ottawa Rough Riders, Montreal Alouettes) from its 1958 inception until 1982, when the Alouettes folded and were replaced the same year by a new franchise named the Concordes. In 1986 the Concordes were renamed the Alouettes to attract more fan support, but the team folded the next year. The demise of the Alouettes, leaving only three teams in the East Division compared to five teams in the West Division, forced the League to balance its playoff structure by moving the easternmost Western team, the Winnipeg Blue Bombers, into the East Division, upsetting the long-standing tradition of "East vs. West", as Winnipeg isn't a part of Eastern Canada.
