Your options are:
1. Request Passport Canada for copies of your national passport.
2. Request CIC for copies of your passport if you submitted it as part of your asylum/refugee/pp case.
Both via the ATIP process as detailed on their respective websites. You need to make the ATIP request clear that you are applying for photocopies of all pages of your x country passport number y issued date z etc. They may charge you for this.
In 1 above Passport Canada may require you to return your CTD, mail you the national passport, you copy it and return it. Why did you apply for a CTD? What date (month/year) were you landed?
