I was wrong about the waiting time for OHIPOHIP waiting time is available here http://www.health.gov.on.ca/en/p ... hip_waiting_pd.aspx
I am updating this post in a lab on campus, so I have to type English.
I think my landing paper confused the officer when I applied for my OHIP for my tentative landing city was Vancouver on it. Therefore, she assumed that I moved from BC to Ontario with Health coverage. If it were my case, my OHIP card would come to effect on July 1. The fact is that I moved from China directly to Ontario, so wating time for my OHIP would still be three full months. I have to go to service Ontario again to correct it.
