you will find many of the above on this government web site

These are all Canadian search sites, Batshaw

Mouvement-retrouvailles may be of interest to you being that you were born in Quebec.

If you have just begun your search you I highly suggest you contact Batshaw, their offices are the only ones who deal with adoption/reunion proccess..unless your adoption was privately done. Hope this helps.
