Despite each receiving FIFA-affiliated status in 1913, both the United States and Canada have lacked a consistent, multi-division soccer system until recently. Consequently, the determination of champions has been problematic at times. The United States did not have a truly national top flight league until the FIFA-sanctioned United Soccer Association and the "outlaw" National Professional Soccer League, which had a network television contract, merged in November 1967 to form the North American Soccer League (NASL). The NASL considered the two pre-merge forerunner leagues as part of its history.
