Nakasuk was born at Qamanirjuaq, a sealing camp not far from Pangirtung. He spent his boyhood at Kingmiruq and lived hunting in that area. Not having a dog team he walked on his hunting trips.
On October 1941, three American navy ships arrived at Linngait (a hunting camp) and wintered there in 1941-42. They spent the winter searching for a possible landing strip with Nakasuk guiding them. When they couldn't find a site for the landing strip they headed down the coast toward what is now Iqaluit. Nakasuk again spent the winter (1942-43) caring for and guiding the Americans in Iqaluit. Two more American ships arrived in July 1943 to help make the landing strip. After helping find the site Nakasuk became one of the first Inuit to settle in Iqaluit. He spent the rest of his life in and around Iqaluit.
When Nakasuk died he was over 70 years old.
