Caplan's (C. Caplan Limited) was a department store in Ottawa, Ontario, Canada. Caplan's began as a small dry goods shop in 1897, and operated over time at various locations throughout Ottawa. In 1916, the store moved to Rideau Street, where it grew into a department store and went on to become a retail landmark in the city. Sam Caplan, born in 1898, ran the store for many years, and became a noted figure in Ottawa's business and Jewish communities.
