He was arrested and charged Thursday with luring a child under the age of 18 and attempting to make child pornography, Toronto Police announced on Friday.
Police say the man allegedly "engaged" a 16-year-old boy through cellphone and internet chats between December 2012 and February 2013. The victim sent images of himself to the accused using his cellphone, police added.
Police say they believe there may be more victims.
At the time of his arrest, the accused was a recruiting coordinator and running back coach of the York University Lions football team. York University said in a statement Friday that Toronto Police notified them of the arrest of this man, who was one of their volunteers.
"We are extremely disturbed about this very serious allegation and are working closely with the [Toronto Police Service] in support of their investigation," the statement said.
"York has suspended our relationship with this individual, pending the outcome of the police investigation."
The accused was scheduled to appear in a Toronto court on Friday morning.
Police are asking anyone with information to contact Crime Stoppers or the Toronto Police Service.
