Found birth father's obituary - he died young in hospital

So I'm 32 years old and just recently applied to get the names of my birth parents. Place of adoption is Peterborough, Ontario I received their names, and starting searching online for more information. I found my birth father's obituary He died before the age of 60, and it appears to have been a natural death. This has me very concerned, and I'm wondering how to seek medical information about this man, or possibly cause of death. Any insight or ideas? Thanks!
