The Globe and Mail reports in its Tuesday edition that insurance adviser Hub Financial Inc. has partnered with robo-adviser Nest Wealth to broaden its investment portfolio capabilities, including adding access to low-cost exchange traded funds for Hub clients. The Globe's Clare O'Hara writes that with 5,000 insurance advisers, Hub is Canada's largest managing general agency -- a specialized insurance broker that acts as an intermediary between independent insurance advisers and insurance carriers. On Monday, Hub signed a referral arrangement with digital wealth manager Nest Wealth that will allow Hub insurance advisers to outsource investment management and gain access to exchange traded funds. Robo-advisers have been gaining acceptance in Canada. The total number of providers has jumped from only a handful in 2012 to more than 15 today. Over the years, several robo-advisers have launched business-to-business platforms. However, not all robo-advisers are finding success in the direct-to-business arena. Wealthsimple, the country's largest on-line wealth manager, is in the process of selling its separate B2B offering -- Wealthsimple for Advisors -- in order to focus on its on-line services for direct consumers.
