The Canadian Immigration process is explained at the CIC site mentioned in
section 4 and also in the various Canadian Immigration FAQs cited in
section 97.  If we try to simplfy it, it consists of a paper screening
phase, in which the documentation required by the local consulate/embassy
are assessed using the criteria determined by the Canadian Government [in
the case of applicants headed for Quebec, by the Quebec Provincial
Government] which employ a point grading system.  After the points are
calculated, you might or might not be called for an interview.  A positive
interview result, or an interview waiver will get you to the medicals check
phase, to ensure that you do not have any illnesses that can threaten the
Canadian populace and/or have ailments that would make you a burden on the
Canadian Health System.  A positive medical result will lead to an
immigrants visa for you and your dependants.  Please note that this
overview is necessarily over-simplified and you are welcome to visit any of
the numerous Canadian immigration lawyer sites and the FAQs [section 9x] to
get a more in depth explanation.
