The first organized competitions were formed in 1883, when the Ontario Rugby Football Union (ORFU) and the Quebec Rugby Football Union (QRFU) were founded. At the time the sport was generally called "rugby union" or "rugby football" because its rules were similar to rugby union's, although this would change drastically in the coming decades. The following year, the two provincial unions would form the Canadian Rugby Football Union, with Montreal winning the first national championship later that year. The CRFU collapsed before the decade was out, but was re-organized as the Canadian Rugby Union (CRU) in 1891, with Osgoode Hall winning the first CRU championship the following year.
