As a cardiologist I work at least 360 days per year.  There are always tests to interpret, urgent requests from hospitals and other specialists for advice.  With current technology I can view everything, including images of echocardiograms for example, anywhere in the world.  When away at a conference I start my day by reading tests before the meetings start and finish my day the same way.    

It would be unlikely that the 6 doctors billed for a full day of services every day, but quite possible to bill for one or two services on holidays or weekends.  It would be easy for OHIP to check on this and I agree that they should.  But to assume that it is automatically impossible or wrong is not correct.
