Twenty-one-year-old Stewart Kenneth Cody McGill, of Bewdley, Ont., pleaded guilty Wednesday to one count of travel to engage in illicit sexual conduct.
Under the plea deal, the parties are asking the judge to impose an eight-year prison sentence.
Authorities say McGill travelled in May 2012 to El Dorado (duh-RAY'-doh) to meet the girl.
They were found a few days later near Potterville, Mich.
The girl told authorities at the time she went with McGill willingly.
Prosecutors say McGill told police he met the girl playing "World of Warcraft" online and loved her.
Sentencing is April 24.
