The settlement funds necessary change depending on the size of your family
and your intended destination.  The latest information on the CIC site on
this subject is:

October 1997
Applicants must prove they have enough money to support themselves and
their dependants for six months after they arrive in Canada. The government
provides no financial support to new immigrants. You should research the
cost of living in the region of Canada where you intend to live. You should
take with you as much money as possible to make your initial establishment
easier. You will be required to show proof of your funds. An independent
applicant, upon entering Canada, is required to have at least CAD
$10,000.00 plus CAD $2,000.00 for each dependant.=20
