Chinese Visa from Tianjin International Cruise Port to Beijing International Airport

Our Asia cruise ends at Tianjin International Cruise Port, previous stop is Hong Kong or South Korea. We will take taxi to Beijing International Airport and depart to a third country on the same day. We have Canadian passports. Are we eligible for the 24-hour direct transit? If yes, does the cruise company or do we need to provide some sort of document to show Chinese immigration at the cruise port? Thanks !
