After his hockey career ended, McGee worked for the Department of Indian Affairs in the Canadian federal government.

[7][8] After finishing his schooling in Ottawa, McGee joined the Canadian government's Department of Indian Affairs.

Historian Paul Kitchen has suggested that McGee's rise in the civil service was aided in part by the connections of his father as a clerk of the Privy Council, and of William Foran, a hockey executive who also worked at the Board of Civil Service Examiners, the body that reviewed government promotions.

[10] He played half-back for the Ottawa City rugby football team, winning the Canadian championship in 1898.

[13] On March 21, 1900, McGee was struck in his left eye by a "lifted puck" during an amateur game for a local CPR team.

[30] Despite offers to reconcile by the CAHL, Ottawa joined the Federal Amateur Hockey League (FAHL) for the 1904–05 season.

[31] After a brief retirement from the sport owing to his work in the government, McGee returned, playing in six of the eight FAHL games and tying Marshall for best goalscorer in the league, with 17 goals.

[32] During the season, Ottawa also played in five Cup challenge games against the Dawson City Nuggets and the Rat Portage Thistles.

[33] The Nuggets, who had travelled 6,500 kilometres (4,000 mi) across Canada from the Yukon,[34] were not considered a strong challenge for Ottawa.

After the game, the Nuggets' manager reportedly dismissed McGee's talents, saying that he "doesn't seem to be any great scorer".

[39] Ottawa finished tied for first in the league with the Montreal Wanderers, setting up a two-game, total-goal series for the championship and the Stanley Cup.

Kitchen suggests that McGee's retirement was due to both family pressure and an upcoming promotion he was to receive at the Department of the Interior, which would require his full attention.

[9] McGee was slightly shorter than the average Canadian man, but he was noted for being strong relative to his size and having a physical, at times rough, style of play.

[36] McGee scored five or more goals in eight other senior games,[46] and his highest single-game total in regular-season play was eight on March 3, 1906, against the Montreal Hockey Club.

"[2] McGee was initially assigned to the 43rd Regiment, Duke of Cornwall's Own Rifles, though on November 11, 1914, he was transferred to the 21st Infantry Battalion and appointed a Temporary Lieutenant.

The Battalion left for England in May 1915, and after spending the summer there, it was transferred to the Western Front in France on September 14, 1915.

[50] On December 17, 1915, he incurred a knee injury near Dickebusch when the armoured car he was driving was blown into a ditch by a shell explosion.

He was given the option to transfer to a clerical post in Le Havre, but chose to return to his battalion, rejoining them on September 5.
