Hi Guys,
I think the procedure should be same as you were applying as first time together.
You should follow the
CHECK LISTS of CIO and Visa Office.AND dont delay informing visa office, as their guide specifically mentions to inform them immediately.
Stuff I can remember, that, you should Send(also refer to your check lists) :
- Fee Submitted @ 550CDN,
- Schedule 1 Background declaration,
- Family History form,
- Travel Details (Required by London, others check their Visa Office list).
- Photos as required by the Visa office (Refer to your visa office specific check List)
- Passport Copy of your spouse.
- Birth Certificate of your spouse (original or Copy as required)
- Marriage Certificate (copy/original as required by visa office, also should be in English or French, of not Translate),
- Marriage Photos (as are required by some visa offices)
- Spouse's Academic documents (as needed by Visa office check list, Transcripts etc as well)
- Spouse's Experience Certificates etc (as needed by Visa office check list)
- New Proof of funds, that shows you have money for 2 individuals.
And anything else you can remember

hope this helps.
