The 2015 federal election again saw Duguid running as the Liberal candidate in Winnipeg South; this time he was elected as the Liberals replaced the Conservative majority government with one of their own, which also included winning six of Winnipeg's other seven House seats. After the election Duguid was appointed as parliamentary secretary to the Minister of Families, Children, and Social Development, Jean-Yves Duclos. Duguid was then named Parliamentary Secretary for the Status of Women on January 28, 2017, serving under Maryam Monsef. He was a member of the Canada-China Legislative Association and served as vice-chair of the group. He traveled together with multi-party colleagues of the association for a two-week tour through China in August 2017. Duguid was also a member and vice-chair of the Canada-Africa Parliamentary Association.
