Grand-Mère had one of the better amateur sides in hockey in the early to mid-1910s, with Ritchie as one of its key players, and in 1913–14 they played for the Allan Cup against the Regina Victorias, losing out in the final series 5 goals to 10 (4-6, 1-4).

[2] Ritchie turned professional in 1914 when he signed as a free agent with the Quebec Bulldogs of the National Hockey Association.

[1] A couple of weeks later, on January 2, 1918, the Wanderers' home rink, the Montreal Arena, was destroyed in a fire.

The team withdrew from the league and Ritchie was selected by the Ottawa Senators, with whom he played the remainder of the season.

In the middle of the 1918–19 NHL season, on January 17, 1919, Ritchie signed with the Toronto Arenas and played in four of the club's remaining ten games.
