BMO Nesbitt Burns is BMO's private-wealth and brokerage division — minimum account size effectively $1M for full-service advisors, though they accept smaller accounts via "BMO InvestorLine adviceDirect" hybrid. Senior advisors here have direct relationships with BMO Capital Markets research, alternative investments, and corporate banking — useful for incorporated professionals and business owners.
BMO Nesbitt is well-positioned for the "incorporated professional" client — doctor, lawyer, dentist with $1-5M in personal + corporate investment accounts. Their advisors coordinate with BMO's commercial banking, tax, and trust departments under one umbrella. For a basic 2-account RRSP/TFSA family with $300K, the BMO Nesbitt experience is overkill and the fees outpace value. Stick with BMO InvestorLine self-directed unless your assets exceed $750K.
