It is becoming increasingly clear to me that one thing Canada *desperately* needs is domestic payment processing capability that's independent of the US, which means no Mastercard, no VISA, no AmEx, no PayPal.
If the US decides to limit those platforms, our ability to do business with the rest of the world is severely curtailed.
Not only should the sale of Moneris be blocked, the infrastructure it depends on needs to be replaced... unless the plan is to use the revenue from the sale to build a solution that works with the rest of the world.
