Canada – October 24, 2026 -- A set of Canadian banking case studies shows how mortgage insurance premiums, 0% balance transfer offers and card disputes can raise costs for ordinary customers.
Homebuyers and balance transfers face extra costs
Mr. and Ms. D put down less than 20% of the purchase price, so Canadian mortgage rules required an insured mortgage. The bank arranged the insurance. Their case centres on late disclosure of a higher premium, which added costs for the couple and ended in a low settlement.
Ms. J called her bank about a promotion offering 0% interest for 12 months on balances transferred from other cards. The bank confirmed the offer and a 3% transfer fee. Missed payments later increased her interest costs.
Ms. W always paid her cashback card in full. The 0% offer would have saved her money compared with the usual 20.99% on balances and 21.99% on cash advances. She later challenged the interest charges she received.
Card disputes turn on delivery, security and bank errors
In June 2025, Mr. D paid by credit card on a Chinese e-commerce platform. The tracking number never showed activity beyond its creation, the delivery date passed, and the seller gave no meaningful response. He received no refund or replacement, which led to a chargeback dispute.
Mr. E, a Bank Y customer for over 40 years, was a victim of fraud, but the bank was not held responsible for the loss. In another case, a consumer was held responsible for unauthorized debit transactions after not taking enough care to protect his card and PIN. Ms. Q, who used a prepaid credit card after returning to Canada, was found not responsible for her bank's technical issues.
Account closures and business fees test long-term customers
Mr. K opened a personal chequing account at a Canadian ABC Bank branch and said he would travel abroad and rely on the account to send money home. The bank gave him 30 days to close it. Mr. G, a business customer for 30 years, questioned significant fees on his business account.
