A 10-year-old boy visiting Niagara Falls, Ontario with his family was seriously injured Sunday when he fell about 80 feet off a railing into the gorge near the base of the Horsehoe Falls. 
  
 Niagara Parks Police reported that they were called to the Niagara Parkway near the Horseshoe Falls at 4:34 p.m. 
  
 The child was visiting from another country and was sitting on the gorge railing so his mother could take a photo. When he tried to adjust himself for the picture, he lost his balance and fell into the gorge, police reported. 
  
 Members of the Niagara Falls Fire Department, Niagara Parks Police High Angle River Team and Niagara Emergency Medical Service reached the injured boy and stabilized him so he could be taken to the hospital. They said his injuries initially were considered to be life-threatening. 
  
 The child was flown to McMaster Children’s hospital in Hamilton by Air Orange. The hospital later reported the child was in serious, but stable, condition. ||||| Image copyright Getty Images Image caption Millions of tourists visit Niagara Falls each year 
  
 A 10-year-old boy is in hospital after falling about 30 metres (100ft) over the railing at Niagara Falls into a gorge below. 
  
 Police told the BBC the boy was sitting on the railing so his mother could take a picture on Sunday. 
  
 He apparently lost his balance and plummeted backwards, striking his head. 
  
 A helicopter took the boy, whose injuries were initially described as critical, to McMaster Children's Hospital in nearby Hamilton, Ontario. 
  
 Police said the boy was now in a stable condition and they were still investigating the incident. 
  
 The boy was visiting Niagara Falls on the Canadian side with his family when they stopped to take a picture at the Horseshoe Falls, the largest of three waterfalls that make up Niagara Falls. 
  
 About a dozen people have gone over the falls since 1901, usually intentionally, inside a barrel or some other kind of protective device. 
  
 In 2017, Kirk Jones died after going over the falls in an inflatable ball after surviving a similar stunt in 2003. 
  
 In 2011, a Japanese exchange student died when she slipped and fell into the falls after climbing a pillar to get a better view. |||||

One family's dream vacation at Niagara Falls turned into a nightmare over the weekend when a 10-year-old boy toppled off a railing and fell into a gorge. Police say the boy was on the Canadian side of the falls when his family decided to take a picture of Horseshoe Falls, the largest of the three falls composing Niagara Falls. He was sitting on the railing having his picture taken by his mother when he apparently lost his balance, fell over the railing, and plunged 100 feet, injuring his head, the BBC reports. Police say they were called to the scene at about 4:34pm, the Buffalo News reports. Members of the Niagara Falls Fire Department, Niagara Parks Police High Angle River Team, and Niagara Emergency Medical Service were able to stabilize the boy so he could be taken by helicopter to McMaster Children's hospital in nearby Hamilton, Ontario. The boy's injuries were originally considered life-threatening, but the hospital later changed his condition to serious but stable. (A daredevil's very peculiar death at Niagara left cops perplexed.)
