Hello Dear
I have some friends who are living in Canada, well accommodation is not a big problem there. First of all I would advise you dont even think about going with your entire family. Yes if you are financially sound, then you can take chance, but I would recommend that first of all you go all alone, search a good house for you and your family and then bring them after you are mentally prepared, and to search a proper work is also a big question there. Well Toronto is a very costly city so atleast book an appartment in advance by using a proper accommodation website.
Well it depends upon you which type of house you may like to live in. First of all study the wheather conditions in Toronto, then take some advise from the peole you know who are already there or others whom you can trust. Take the decision very wisely as things are not easy as we think in that country. From the day first you apply for a bank account and a credit card and then try your best to get a driving licence. For driving licence I advise you to apply from Sudbury which is in Ontario I have heared that procedures gets completed faster there. Anyways still if you have any doubts then do ask me.
