Aaron was sent to Palestine, where he lived in the Atlit detainee camp, attended school in Gan Shmuel, and joined Gadna, the youth division of the Haganah. When the Israeli War of Independence broke out, Aaron served in the Palmach until the end of 1949. After his discharge, along with others, he founded Kibbutz Nir Yitzhak in the Negev where he lived and worked until 1952. Aaron then came to Canada through Pier 21 to visit his family in Toronto who had survived the Holocaust and he stayed.
After working in a clothing factory, he worked in construction and saved enough money to open a hardware store. Aaron built a storefront and apartments above his successful hardware and building supply business that continued for over 50 years. He was also involved in building sub-divisions in Thornhill and commercial buildings and factories in the GTA.
