Your case illustrates why the subtleties of citizenship and PR card process and policy are important. When people's lives are involved, these subtle points of policy can have huge effect.
Separating spouses from one another and children from their parents for untold months should not be a requirement of a humane immigration system.
This is another reason why the record citizenship processing delays are important. I encourage your husband to write a letter to his MP explaining the citizenship delay is effecting him (as a citizen), his children (as citizens) and his wife (longtime PR). The citizenship delays do not just affect immigrants, they effect Canadian families, Canadian workplaces & Canadian lives. Citizenship rights are not just about immigrants rights, but the rights of Canadian citizens to keep their families together.

I Agree, fair enough!
