 There were, however, several disputes with the Canadian Rugby Union and the Quebec Rugby Football Union that prevented the Tigers from competing for a national championship from 1903-1905.It was not until 1906, where the Tigers finally agreed to play the QRFU rules, that Hamilton defeated McGill University anyway, by a score of 29–3, to become Dominion Champions.The Interprovincial Rugby Football Union was formed on September 13, 1907 in an amalgamation of the Tigers and Toronto Argonauts of the ORFU and the Ottawa Rough Riders and the Montreal Football Club of the QRFU.
