He was again re-elected in 1940[5] and, with the loss of two other Liberal MPs in Toronto, was again the city's only representative in the Liberal caucus[4] With two other MPs, A.A. Heaps of Winnipeg and Sam Jacobs of Montreal, Factor fought against quotas on Jewish immigration and anti-Semitism.
[6] While serving in Parliament during World War II, Factor enlisted with the Royal Canadian Air Force, retiring in 1944 with the rank of Squadron Leader.

He attracted notice as a judge for his attitude towards drug addicts viewing them as individuals with an illness rather than criminals and pleaded with the federal government to change the law so that they could be sent by the court to hospital for treatment rather than prison.
