I have tried to get his Pow records from the Government of Canada without any luck. Is there anywhere I can access to get his military records or any further information?
With a bit more information, like his name, I might be able to help you navigate Library and Archives Canada. There is a list of microfilms with the paychecks of POWs (yes, they were paid for their labor). It is in alphabetical order. The medical files are restricted, so you might need to make a request to access the information.
