The Department will place this information on a public website at http://xnet.env.gov.ab.ca/imf/imf.jsp?site=rec_access (Bookmark this site). Before going onto the land, the recreational user must get in touch with the person leaseholders have named as the contact person for the grazing or farm development lease. If this information is not provided, the recreational user can come on the land without contacting the leaseholder.
Obviously you must ensure you are on the lease with no contact info as listed on the website. You can reference it with GPS coordinates to be certain.
