1. On sponsor questionnaire, there are questions of my previous residences outside of Canada...I can remember back to 2000 as far as addresses are concerned, but phone numbers? They are long out of date. A problem?
Put as much of the info they ask for as you can. If there are details you have forgotten and can't find out, just attach an explanation of this. As for old phone numbers that are no longer yours - just include them anyway. I did note in my form when the numbers were a cell phone.
2. On the same questionnaire IMM5540, question 11 asks for proof of intention to re-establish in Canada and details of plans to do so. Well, I am a teacher, but have no job yet, or rental agreement. How can I answer these in an acceptable manner? We would consider a down payment on a house once we got there...want to get there in July 2012...any advice here?
Explain your plans and offer whatever proof you can. You can get letters or affidavits from family members or friends if they will be helping you in any way when you first return - people who will be staying with their parents while they get reestablished get an affidavit from the parents about this, for example. You can show correspondence with potential employers, landlords, and real estate agents. You can show how you are planning to end your stay in China: for example, correspondance with moving companies or storage companies. Proof you and your wife have given notice at your current jobs. Proof you have told the children's schools they will be leaving and have made arrangements for their schooling in Canada.
