For Kitchener:
- I advise parking at KPL underground lot. It's pretty cheap and covered! That's on Queen Street.
- Once finished, hike down the street to the RBC building across from the green parking garage -- 2nd floor is the Service Ontario you need to go to to update/apply for OHIP. They are usually not busy at 9am. We were out in 15m.
- Service Canada is on the opposite side of Frederick Street to CIC, in the Market Square (this is opposite side of Duke to the Court House). There you will spend a little time, because they do process EI and other benefit related cases on a walk-in basis.
They will print you a SIN immediately (usually). In my wife's case, she had a temporary, but I think I heard her mis-spell her fathers name from the previous time. Which prompted a mail-in request.
