Where to put invitation letters?

[goms]

So my sister will invite me and my common-law in Canada for a vacation.

I have answered Eligibility Assessment online and continued until the last questions to come up with the checklist needed.

However, Letter of Invitation is not included in the checklist, where will I include the letter of invitation, proof of income, PR cards etc of my sister? They should be in just one .pdf file right?

Please help me. thanks!

It's because the letter of invitation is optional.
