Yes. It makes sense to put them together.
Starting with PV-46, this amendment seeks to include those veterans who are suffering PTSD by eliminating the requirement for immediacy in symptoms. PTSD often manifests long after the incident that caused the initial trauma. This problem was brought forth to us by the Canadian Legion, including Branch 5 right in my own riding of Thunder Bay—Superior North.
Moving to PV-48, this is the same as PV-46, as well as accounting for the event of multiple incidences that cause injury. For example, PTSD is caused by exposure to extreme violence and repeated violence over a period of time.
