I completely agree! It's nerve-racking!
First off, here's the suggestion from billhyatt on the format:

It really depends on your actual personalised checklist but for me here's what I will be compiling in my LOE:
- travel and personal history - table of all visits and addresses (

- Ontario Nomination cert + Schedule 4
- Moving work exp to personal exp due to lack of details provided by company and/or not claiming points for.
- passport scan quality (200dpi for current passport, 100dpi for previous passports)
- husband's work experience moved to personal history due to foreign experience (not Canada)
- legal name change, in our home country only marriage cert is required. In my country of origin where I am PR, they require marriage cert + updated passport.
- PCC, home country provided but country of origin requires letter from IRCC.
- Proof of funds, explaining the 3 accts I will present: 1 completely savings (joint acct) , 1 payroll acct + usd savings acct, 1 savings acct for my son under my name and his name.
Not super common:
- stamps for country of residence on passport, they are not shown because we use a chip at the immigration and our thumbprints.
- ref letter from my son's pediatrician to explain height and weight.
- relatives document, photos of docs rather than scanned.
Hope this helps. Please let me know if I missed anything!
