An organization that isn't a dedicated banking service might not adhere to that model since it's not a dedicated banking service. Obviously that's the point I was making, that Canada Post has the chance to branch out and is uniquely flexible in the space, so they would have the ability to integrate some auxiliary services into their business model without much disruption at the post office level.

This approach also doesn't have additional personnel overhead since Canada Post already have staff and established locations. Cross-training postal employees is a lot easier and cheaper than having to establish and maintain a bank branch, especially one that offers mortgage/insurance brokerage or investment products. Canada Post wouldn't necessarily need to offer that, especially not right away.
