Q. How is online validation different from OHIP IVR?

A. Both services are provided by OHIP.  The difference is in the way used to access the service and the format the validation results are received. 

Web-based validation is the newer method and has several advantages. For one, the results stay on the screen and could be saved so you don't need to write things down. Another is the simplicity and speed. All this produces more timely and accurate results.
