TRV inside Canada question.

[cec4111]

Hello, I applied for TRV inside canada for me and my wife seperately through online. I couldnt do it together as it was showing some issues. I called up CIC and they asked me to do it individually.
NOw i got confirmation and a request for passport.

Should I send both seperately with seperate return envolpes or one should be fine, Also please specify the address i have to mail my passports.

Thanks,
