Marks began intermediate-level play for Belleville of the Ontario Hockey Association (OHA) in 1899.

When the Federal Amateur Hockey League (FAHL) started in 1904, he joined the Brockville team for two seasons.

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.

After the Wanderers folded, he was assigned to the Canadiens but was loaned to the Toronto club, winning the 1918 Stanley Cup.

During the 1908–09 season, while with the Brantford Indians of the OPHL, Marks and the Indians were involved in a train accident outside of Guelph on January 14, 1909, where Marks suffered season-ending injuries (broken arm and fractured ribs) when the rear coach of the Grand Trunk Railway passenger train they were traveling with ran into a ditch and overturned.
