When you land in canada, if you get your SIN number at the ariport, thats great, but if you are not in a hurry, go home and have some sleep or take rest. you can go to any Service Canada near your house and get your SIN card. After that, you can go to any Service Ontario and get your Health Card, 1st they will give a document (which will also act like your Health Card), and the Original Health Card will be delivered to you within 15 Days. Also you might consider to go for the G1 Test in designated G1 Test centres so that you can get your G1 Driving License. But you can't drive with G1 Driving License card, you need to have G2 Driving Test in order to Drive.
1 piece of advise, if you have a license in your home country, get a document from your RTC so that you can show that Document in the Test centre which will add that experience in your Canadian Driving License.
PR card will be delivered between 50-60 days in your canadian mailing address eversince you made an entry at the Airport..
Rest all the other cards like health and Driving license takes about 15 days to be delivered.
Enjoy !!
