Maybe you wanna know one of these?:
- cancel all insurances u don't need. (Car, life, accidental, pp.)
- think about your bank account in you current country- do you still need it?- how much money do you keep there
- cancel phone, cellphone contracts.
- see that there are not to many letters you wil receive while beeing in Canada already. So look for an address u can send ur mail to before u leave.
- inform as many institutions as u can that you leave, delete as many customer # (catalog companies, pp.) as u find/remember
Just to give u an idea... Hope it helps!
