ISBNs are free to register in Canada, which in my mind, is awesome. But I have some questions.

If I were writing under multiple pen-names and wanted to order a block of ISBNs for the purpose of self-publishing, what name do I order the ISBNs under? My legal name? My pen-name? Is there a way that people can connect my pen-name to my legal name though the ISBN?

If I use this ISBN in my Createspace or Smashwords account instead of their own, will it connect to my legal name?

Thank you.
