Tarion Enrolment Number

Hey guys, I bought a resale condo that was constructed last year. I’m trying to file a warranty claim with Tarion but I am being asked for an Enrolment Number of the condo unit in order to register for an account with Tarion.

Since this unit was purchased as resale, I do not have that Enrolment Number from the Builder.

Does anyone know how I could get this Enrolment Number to register with Tarion?

Thank you.
