If anybody has used Winnipeg tap water to dilute the coolant in the
past, that could explain why the rad would be corroded.

You didn't mention how often the cooling fan(s) are running. Water pump
runs all the time, so, unless the impellers are corroded OFF the pump,
it's not a likely suspect. It should still be replaced as part of the
timing belt schedule.
