Once you have accumulated real money, you might expect your bank to start treating you differently. If you have $100,000, $250,000 or $500,000 spread across an RRSP, a TFSA and a taxable account, surely handing all of it to one institution must buy something. I wanted to know what.

I do not mean private banking, and I do not mean someone with a family office. I mean the much larger group of Canadians who have built a few hundred thousand dollars of investments, own a house with a mortgage or a HELOC, carry a premium credit card, and keep financial accounts scattered across several institutions because that is how they accumulated. For that household, the question is practical: does giving one bank more of my financial life actually pay?
