what should i do and what i need to do if i need to move to frence and
live there? I am a canadian

Dear Red Eye, 

There are so many things that you should do, that it would probably
not encompass a $2 question!

However, here are som guidelines that would fit your pricing of this question: 

(1) You should get legal permission to live in France. For that, you
have to contact the nearest French Consulate and get all of the legal
matters sorted out:
French Consulates in Canada
<http://www.ambafrance-ca.org/article.php3?id_article=472#sommaire_1> 
The consulates are supposed to give you all the details on what are
the requirements, and what kind of documents you should bring with
you.

Canadians, unlike citizens of EU countries, need permissions (visas)
to stay in France. You can get different visas, depending on your
goal: student's visa (to study in the country), residential visa and
work permit (to live and work, either for a limited period or
indefinitely). However, French Canadians, as people belonging to the
French cultural areas, may find it easier than others.

(2) If you don't know enough French, it should be a good idea to know
the language before you immigrate. If you plan to live in the country,
you should know the lanaguage and the culture.

(3) After you've received a visa from the consulate - even a temporary
one (but one that enables you to work) - to live and work in France,
you have to try to find a job in the country; unless you plan to move
there in order to retire. This Google search would provide at least
some of the answers:

I hope this answers your question. Please contact me if you need any
further clarifications on this answer before you rate it.

Do you mean France?

You may want to investigate if you have a claim to citizenship of ANY
of the 25 EU states. The advantage of this is that it will simplify
the problem of legal residency in France when you have obtained a
passport of another EU state. The disadvantage is that it may take
longer than is what is practical
for your future plans.
