So long as the flight into O'Hare is not Air Canada, then UA will probably arrange for not too much rushing from flight to flight.

However, I frequently end up having to move briskly from terminal B (inbound from Ottawa on UA) down and through the tunnel over to terminal C for the outbound flight. There's time, but not a huge amount, especially if you have to find your way for the first time.
