When I landed 12 years ago,
1)The first thing we did after landing to the airport, my sister drove me to the Service Canada(used to be called something else before

) office and me and my dad applied for SIN number(to make sure,we are job ready A.S.A.P)
2)My sister got us a Brampton city bus pass for the whole week and we spend about 3 hours every day just to know the city we live in.
3)We were ready to do any job(factory or desk job) and we applied to multiple job agencies.
4)Although we spoke good Indian English, It was very hard for us to understand Canadian English accent and we interacted with people for this sake asking time, bus route, talking to a mall shop persons, asking the driver for best route etc and we watched bunch of TV series to get familiar with accent.
5)After, we got our SIN number, I believe we applied for OHIP card, bank account, library account etc.
6) The Brampton library had great pamphlets with various information.
