Steckley is reportedly the last known speaker of the Wyandot (or Huron) language, which he has studied for over thirty years. He is also interested in place names as derived from indigenous languages, and aims to correct common misconceptions regarding their original derivations.
Steckley has become a deeply respected figure amongst the Wyandot. On his adoption into the Wyandot tribe in 1999, he was named Tehaondechoren ("he who splits the country in two"). He was also given the name "Hechon" by descendants of the Huron in Loretteville, Quebec City, while teaching them their own historical language. This was a name that had previously been given to Jean de Brébeuf (1593–1649), one of the North American Martyrs, by his Huron and Wyandot followers.
His 2007 Huron-English dictionary was the first book of its type for over 250 years to be published.
In 2007, Laval University received a federal grant of $1 million for development of its Huron-language teaching materials in collaboration with Steckley.
