PR card extension 2 valid passports

[IvanVano]

Hi! I have 2 valid passports by the time of PR card extension and citizenship application. One of those I used to enter Canada when I got PR status and the stamp. However later when I traveled to and from Canada I sometimes used my first passport, sometimes the other. Though not every entry to Canada was stamped by border officers.
Which copy of biographical page of these passports should I submit at the time of PR card extension? Is it important to submit copies of other pages including stamps? Do I need to do it from both passports? As I haven't found any mention about other pages in the guidance.

You most certainly want to use both passports. If they find you have more than one valid passport (and have had since becoming a PR) they will wonder why you didn't include both of them. If you recently obtained a citizenship in another country allowing for a secondary passport then CIC should also be made aware of this as you could use either for your travels and both must be examined.

These both passports are both from one country and the second one was received after I obtained PR, however they're both valid at the moment

Either way they both need to be included and examined for both your PR renewal application as well as your citizenship application.

I find it very difficult to believe that any country would allow you to have two valid passports in operation. Normally any existing passport is voided when the new one is issued, even if is not physically voided by the issuer. Or, is one of them a diplomatic or government passport?
