A two-year-old boy has died after falling 11 storeys from a Toronto highrise balcony Tuesday morning.

Police said the child fell from a building on Shuter Street in the Regent Park area just after 8 a.m. ET. He suffered head injuries and was declared dead after being taken to hospital.

The boy's mother and two other children were home when the boy fell, police said.

Workers with Toronto emergency services told CBC News that they have responded to 10 calls of falling children since May.

They urged parents to be vigilant in supervising near windows, balconies and decks. Windows should be fitted with locks to prevent them from opening more than 10 centimetres.

At a news conference Tuesday, Toronto police also urged parents to explain the dangers of falls from windows or balconies to their children.

This is the second serious fall in Toronto in three days. On Sunday, a toddler suffered serious injuries after he fell from a second-floor balcony in the north end. The boy is expected to fully recover.

On June 26, a three-year-old boy fell to his death from an apartment on the top floor of a 15-storey building in Ottawa.
