In terms of gridiron football the Hamilton Tiger-Cats of the Canadian Football League can trace their roots back to the Hamilton Football Club (nicknamed the "Tigers") which formed in 1869, then later merged with the Hamilton Wildcats in 1950 to form the current franchise. Their rivals to the north, the Toronto Argonauts, were founded four years later in 1873 and have a mostly unchanged franchise history. Both clubs began as rugby football clubs and only later adapted to the gridiron-style of play which would become known as Canadian football. The oldest continuous rugby club in North America which still plays rugby is the McGill University Rugby Football Club which was established in 1863, although their first recorded game was not until 1865. The oldest independent (non-university) rugby club is the Westmount Rugby Club of Montreal, which formed in 1876.
