Lake moved back to Canada in 1907, playing first for the Winnipeg Strathconas then the Winnipeg Maple Leafs. As a member of the Maple Leafs he would play in an unsuccessful Stanley Cup challenge against the Montreal Wanderers in 1908.
For the 1908–09 season, Lake signed with the Pittsburgh Athletic Club of the WPHL. However, after three games he was released because of his rough play. He was signed by the Ottawa Hockey Club of the Eastern Canada Amateur Hockey Association (ECHA) and helped Ottawa win the Stanley Cup. In the early years of his hockey career Lake had been a left winger, but with Ottawa he was converted into a defenceman. He would remain a player with Ottawa for four seasons, winning another Stanley Cup championship in 1911, before being traded to the Toronto Ontarios in 1913, where he played for one season. For his final season, he returned via a trade to Ottawa. He only played two games for the Senators that season and retired after the season.
