If we move Seattle to Canada,my wife is sure she can find work,my
retired income about $5,000/mth.We have 5 grown kids.With our  new
Canadian residency, do you think they will be allowed to live
in Canada with us as there sponsors? What advantages do we get living
in Canada, other than not having an idiot as our national leader? What
type of social security will our kids be able to earn in
Canada? How long does it take to get qualified for medical and other
Canadian benefites?

Your wife should indeed find little trouble working in Canada.  We've
had a serious issue with nursing shortages, and of course senior
nurses are all the more valuable.  Your primary resource for questions
of this sort would be the Canadian government's Citizenship and
Immigration website, located here:

The "skilled workers" section should have information directly
applicable to your wife's situation.

As for the longer-term scenario of bringing your children to Canada,
I'm not clear on how that works.  It is not especially difficult for
Americans to move to Canada and gain the legal right to work; and
socially it is not as difficult to adjust to Canadian life as it would
be in many other countries.  We share a language and many common
cultural characteristics.  This is not to say it wouldn't be an
adjustment.

To look into this further, the phrase you'll probably want to search
on is "Landed Immigrant Status," which is a sort of citizenship lite,
if you will.  If you decide to stay long-term, Canada does permit dual
citizenship for Americans.

Unfortunately I do not have time at present to research this question
for you properly, or to comment at length on such social advantages as
you may derive.  Perhaps another Canadian-based researcher
(Knowledgeseeker-ga, for example, is an American ex-pat living in
Canada) may wish to take this on.

You are moving to avoid a President is in his last term?  OK (shrug).

But the next Prez could be even worse.

Unlikely but possible.

If you don't like Bush, why doesn't your  political party:

1. develop a true platform, other than "Republicans are bad"?  You
haven't had a new idea since 1935.

2. Run a person who is qualified for the job. No rapists; no
pathological liars no matter how charming; and can keep their pants on
while on the job?
