Durham Regional Police say two workers were found dead after crews pulled them from a trench following a construction site collapse.
Police said the incident occurred on Rossland Road between Ravenscroft Road and Westney Road on Monday afternoon when four workers became buried in the trench.
Two of the four workers were pulled by crews hours later early Tuesday and were pronounced dead, police said.
The other two had been rescued and were taken to hospital.
On Monday, a spokesperson for Ornge Air Ambulance said a man in his 20s was taken to Sunnybrook Health Sciences Centre with serious injuries.
Police said another man was taken to a local hospital with minor injuries on Monday.
A spokesperson for the Ministry of Labour, Immigration, Training and Skills Development said the constructor is Grascan Construction Ltd. and the employer of the workers is Direct Undeground Inc.
It is unclear how the trench collapse occurred and the Ministry said the investigation is ongoing.
