Hi,
I want to share with you what i did in regards to OHIP. I applied for OHIP based on the PER email I received from CIC. They rejected my request because they were looking for an official letter from CIC not an email!. They gave me an eligibility assessment form which state the reason of decline. I appealed against the decision. I sent that form along with PER email, any document that prove that I have an address in Ontario and a cover letter to describe my case. That is, based on the PER email, I am eligible for OHIP but i was rejected because i don't have a letter from CIC which CIC don't issue anymore. OHIP sent me back a form to sign which they submitted to CIC to check my immigration status. They replied to me with the a letter confirming that I am eligible for OHIP for one year that can be renewed for another year. Now I have OHIP coverage ;D. Of course you should take that letter with other documents to any service Ontario office to apply for OHIP.
For those of you who have dependents, I did not apply for my wife at the first time and now I am going through the whole process again hoping that she will be granted OHIP. So, when you go to Service Ontario office for the first time, take your dependents with you just to get the eligibility assessment form "request denial" for all of them and then include them in your appeal. Don't forget to submit any related documents (i.e. tax assessment report for your wife that shows her address in Ontario). Check service Ontario website for required documents.
WIsh you the best,
