I left Canada in 2005, and now I have just returned back. I know that OHIP has expired and I also know that there will be 3 months waiting time before I can use any of the services. But my question is do I need to apply immediately or wait for three months to pass and get some temporary coverage in the mean time. Is it three months after I apply for it or is it three months after you enter in Canada. In other words if I apply say after 4 months, will it become active immediately or will I have to wait another 3 months after the application?
