I am ready to buy this patent (CA 2,505,802 A1), and am wondering how and who to contact about it.

This application was filed only in Canada and never granted. It has been considered to be a dead application since April 29, 2009, due to CIPO being unable to deliver the Maintenance Fee Reminder (returned to sender, moved/address unknown). You can find all of this information in CIPO.
