hi, i think u can. there exist a lot of exchange programs between quebec and french universities. and if u take some time and read some basic information in quebec universities' sites, u will know how to proceed: for example, in mcgill's site, u will be told which doploma u have can make u eligible for a quebec diploma.
this is not like european system in which the credits can be exchangeable.
here u must ' faire votre candidature par le processus de l'équivalence'.
in france, licence 3 ans + master 2 ans + doctorat 3 -5 ans
in quebec, baccalauréat + master+ doctorat
look, the same thing.
frankly speaking, the process of equivalence is much better than the recourse to the credit exchange.
ask your husband to inquiry the school perhaps also helps.
