In order to get some help determining whether or not he may meet the the residency requirements for Citizenship, you may want to use the Citizenship Residence Calculator.
This calculator will help him determine on which date he can apply for Citizenship.
Your husband must meet the citizenship residency requirement in order to apply for citizenship. If he has not lived in Canada for 3 out of the last 4 years, then he does not qualify and should not apply along with you. He will have to wait until he does meet the residency requirement before applying. There is no way around the residency requirement. He has to meet it if he wants to become a Canadian citizen.
