The Passport Request email show that:
"Ø Submit Original Passport/Travel Document: Valid passport or travel documents for yourself and your accompanying dependants. If you and/or your dependents hold a Taiwan or Hong Kong SAR passport, or your passport otherwise exempts you from obtaining a visa to visit Canada (see: http://www.cic.gc.ca/english/visit/visas.asp#exemptions), send a PDF copy of your visa-exempt passports (all pages) to this visa office. All passports must be submitted together."
Trying to upload a PDF copy of HKSAR passport to HKVO, when I click in the link and select "Hong Kong Special Administrative Region" the link show on the following:
"Hong Kong Special Administrative Region
You need an eTA to visit or transit Canada by air if you hold a valid and subsisting Special Administrative Region passport issued by the Hong Kong Special Administrative Region of the People's Republic of China.
If you travel by land or sea, you will not need an eTA when you enter Canada. However, you must travel with proper identification.
Note: U.S. citizens do not need an eTA or a visa. However, proper identification must be presented at the border.
Applying for an eTA is a simple online process that takes just a few minutes. You will need your passport, a credit card, and an email address. It costs $7 CAD to get an eTA and it will be valid for up to five years."
Is that means I need to pay CAD$7 when I upload the passport via online under passport request from family sponsorship section? And what is eTA?
