Kanata, Ontario
Canada was also a pioneer in the production of medical isotopes, and today is the world's biggest supplier of Molybdenum-99, the "workhorse" and most commonly used isotope in nuclear medicine. This isotope is generated in the NRU reactor; this is then shipped to MDS Nordion, a global supplier of radiopharmaceuticals based in Kanata, Ontario (near Ottawa). There are more than 4000 Mo-99 treatments daily in Canada, and 40,000 daily in the US. Canada produces about 30-40% of the global supply of molybdenum-99.
