#8. Richardson Family
Major holdings: James Richardson & Sons
What began in 1857 as a one-man grain-merchandising operation in Kingston, Ont., is now a multi-enterprise international corporation comprising agriculture, food processing, oil and gas, property management and a private-equity arm. The family’s wealth is largely controlled by Hartley Richardson and Carolyn Anne Hursh. While the independent wealth management firm Richardson GMP, which has $28 billion in client assets, is probably their best-known asset, most of the family’s wealth comes from its holding company, James Richardson & Sons.
