No. I read the email again and it clearly says dont send passports for US. Also, the only photocopy of photo page and any amendment page is required. Not all pages.
Here is the text from the email-
If you hold passport(s) from countries whose citizens need an eTA to travel to Canada or hold passport(s)/travel document(s) issued by the United States , you DO NOT need a Permanent Resident Visa to be affixed in your passport. Please do not send your original passport(s). You are required to submit one photocopy of the photo page and any pages containing amendments of the passport for you and for each accompanying family member. Please ensure that your passport(s) for which you will submit a photocopy is valid for at least 6 months.
