Patriarch Arthur Lowe (Gerard Parkes) was a doctor who ran a family medicine clinic in a working class downtown neighbourhood with nurse Marge (Sheila Moore), and was married to housewife Hannah (Kim Yaroshevskaya), a Jewish immigrant from Poland.

Sidney, who was too young at the start of the series to register for military service, resented being unable to serve but signed up for the Royal Canadian Air Force when he reached enlistment age.
Jakob was Hannah's nephew, a Polish refugee who had come to live with his aunt and uncle in Canada to escape the rising tide of European anti-Semitism in the leadup to the war;[3] initially a supporting character, he became much more prominent after Sidney's enlistment.
