yeah. so prepare yourself to fly
it took only 15mins. we went there early last tuesday. you just need to fill up the form and show them the COPR, passport etc. they stooped issuing the plastic card since march of this year. so they will give your social insurance number on a paper based only. it's confidential, so keep it safe.
we tried getting the OHIP as well but we still need the proof of address because we recently moved. but they said it won't take long unlike before you have to wait for 3months for you to apply and avail the card. as long as you have the proper documents, it will be easy as 1, 2, 3. don't forget to bring copies of your marriage certificate. it's very important
