[2] In his new position, Kahanovitch established a central supervisory committee, the Va'ad HaShechitah, to oversee the city's kosher slaughterers.

[4] He traveled to smaller Jewish communities in Western Canada to support them as well, attending, for example, a teacher's conference in Saskatoon and the dedication of a synagogue in Melville, Saskatchewan.

[8] He did not have a daily schedule other than attendance at the regular prayer services, leaving his home open to petitioners at all hours of the day and night.

During his evenings, he would be raising money for the many causes, or performing one of the over 5,000 marriage ceremonies for the Jewish community, each of which was meticulously documented in a ledger as sourced by his family and preserved.

When rumors circulated in 1927 that Kahanovitch might leave Winnipeg, Jewish community leaders raised funds to add to his salary.

[4] Kahanovitch was a founding member of the Canadian Jewish Congress and an elected delegate to that group's first convention in Montreal in 1919.

[5][4] Unlike other Orthodox rabbis who spoke out against the socialist and radical elements in the Congress, Kahanovitch pursued a course of unity with them.

[11] According to his biographer, M. S. Stern: In the early years, it took a person of great courage and conviction to espouse a Zionist orientation, even a religious one, while staying, in other respects, within the mainstream of orthodox life and rabbinic practice.

They supplemented his annual synagogue stipends and donations that he received from conducting wedding ceremonies by maintaining a vegetable garden, chicken coop, and five goats behind their house.

His funeral was attended by an estimated 5,000 people, representing approximately one-third of the total adult Jewish population of the city at that time.
