Yh that different thing . It's mean you have reason to canada for work . It's mean you also help your husband by financial. If you have open work visa then you have reason to go canada . You understand my mean . You need very very storage to go there. But if you apply vistor visa then you need storage reason so visa office think 2 time even he or she want to reject or refused any application. After you reach there its your choice you want to change your visa status or not .
