Travel documents, temporary foreign worker status, and travel during eligibility period

[SupremeLeader]

Hi everyone,
I'm excited to be applying for Canadian citizenship and I'm hoping some of you with experience can offer some advice on a few specific areas:

1. Travel Documents:

• Should I add my Canadian permanent resident card and US B1/B2 visas as travel documents I held during my 5-year eligibility period?

2. Temporary Foreign Worker Status:

• A bit of a tricky one: I applied to extend my temporary foreign worker status on September 2nd, 2021, but the application was "canceled" shortly after I obtained PR status in December of the same year. Was the extension application actually approved? (I'm unsure as it was canceled)
  
  Since it was canceled and not refused, I don't have a "Date of decision for the refused extension." What date do I need to enter in this section? I haven't received any official letter with details.

3. Travel During Eligibility Period:

• The application asks "Did you visit more than one country during this time?" Does this include transiting through a third-country airport without leaving the secure area?

Thank you so much in advance for any help and insights you can offer! I really appreciate your time and expertise.
