I am going from canada to hong kong for 2 days then to Macau to visit my daughter for 5 days

then we are going to Thailand from Macau for 6 days back to macau for 2 days then back to hong kong for return flight to Canada -- Do I need a tourist visa. All my research said no as we are there less than 60 days. What might they be looking for in order to clear immigrations?
