Hi Ja77,
Yes, you said it right. I've sent my full docs to CIC and day after, I discovered I left my husband's old empoyment certificates only the latest one has been included in the mailing envelope. But all these said old certificates has same dates certified true copy from JP together with the rest of my certificates. Hopefully they can considered that I sent it as addendum the following day.
Heaps of thanks to all respondents.
Cheers
