Bluejay,
All your questions are related to POST IMMIGRATION.
First thing is to immigrate, for that best startup point is
http://www.cic.gc.ca/english/index.aspImmigration itself is a long process, once you are through this you start looking for life after that. Offcource during this period you can get info about employment, life, healthcare, housing etc. Internet is a goo source. Almost all the provinces maintain websites and so do major cities.
Thanks
Cool
