What the union is proposing is that Canada Post and the Liberal government look at the different options that are out there.
There are options whereby Canada Post would be a fully funded bank. There are options whereby Canada Post would partner with one financial institution, something like what President's Choice banking has done by partnering with CIBC and then, I believe, with ScotiaBank, or they could enter into a partnership with multiple banks and essentially act as branches for those banks.
The issue is that Canada Post has done an exhaustive study into postal banking. They have an 800-plus page report that's been released, but over 750 pages of it have been redacted. This is not rocket science. Canada Post has already done the legwork of investigating postal banking. Among the parts that weren't redacted were two sentences: one that said that it would be a win-win scenario for the corporation and one that said it would be a proven money-maker.
