He won 2 Stanley Cups with the Quebec Bulldogs in 1912 and 1913. He also won a third Stanley Cup with Toronto in 1918. He was born in Brantford, Ontario.

Marks began intermediate level play for Belleville of the Ontario Hockey Association (OHA) in 1899. He would play for Belleville for four seasons until 1904. He was suspended for a year in 1903 for playing professional baseball in 1902. When the Federal Amateur Hockey League (FAHL) started in 1904, he joined the Brockville team for two seasons. At the end of 1906, he signed up for New Glasgow's Stanley Cup challenge. For the 1907 season, he became a professional with the Canadian Soo team of the International Professional Hockey League (IPHL). In the 1907–08 hockey season, he started with the Pittsburgh Lyceum of the Western Pennsylvania Hockey League, and jumped after three games to Brantford of the Ontario Professional Hockey League (OPHL), eventually playing in the Toronto PHC's Stanley Cup challenge.

He played for Brantford in 1909, and jumped to the ill-fated Canadian Hockey Association (CHA) for four games with the All-Montreal Hockey Club, returning to Brantford after the CHA demise. In 1911, he played again in the United States, playing a season of exhibition for a Chicago professional team which was attempting to start professional hockey in Chicago.

In 1911, he returned to Canada, to join the Quebec Bulldogs of the National Hockey Association, playing six seasons of the club, winners of the Stanley Cup in 1912 and 1913. When Quebec did not play in the NHL's first season of 1917–18, he was drafted to the Montreal Wanderers from Quebec for the start of the inaugural 1917–18 NHL season. After the Wanderers folded, he was assigned to the Canadiens, but was loaned to the Toronto club, winning the 1918 Stanley Cup. He did not play in 1918–19, but attempted a comeback in the 1919–20 season when Quebec AC activated a team in the NHL, playing only one further game.
