Hi CMP - all we did (and this is simple beyond belief trust me) was:
1. Proof of relationship: wrote a letter each and paperclipped them to the letters from friends and family. Attached a typewritten sheet with "Proof of relationship and letters of support". In those letters they each had an informal timeline such as we met at X on x date then little things little what we had been doing throughout and why we wanted to move [back] to Canada. We attached emails in date order (oldest first, and only one from every other month which had things like, "can you pick up some wine for dinner honey" just general stuff) and then things addressed to us both from family friends etc (a wedding invite, christmas cards etc - not many, maybe a couple, plus some photo's and boarding passes e-itineries.).
2. Proof of cohabitation: attached a typewritten cover sheet and listed the items - not detailed, simply 01/01/00 Hydro bill, 01/01/00 c/card statement, 01/06/00 Hydro bill, 01/07/00 c/card statement, 01/01/01 Hydro bill, and so on... This paperclipped package had items addressed to us both (only one utility company bill from the beginning, middle and current months) along with individually addressed items from beginning, middle and current month. Arranged them again in date order (oldest first).
We included copies of degrees and educational certificates - don't know if that had any effect at all, but that's it pretty much. (Along with mandatory items such as photocopy birth certificate etc.)
Same day approval for sponsor and 9 days for London to issue PPR. Landed in December. So all in all, it couldn't have been too bad.
