ADHS lists this lab 2 times in Mississauga with different phone numbers ((905) 201-9998, (905) 712-5100); ADHS explains that one licence can cover several labs, and only one of them is in the city listed. ADHS's detail for licence AZ0848 prints 5623 McAdam Road, Mississauga, ON 86001; 86001 is not a Canadian postal code, so it is not used.

Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Arizona certification program.
