Peel Police – Update To The Explosion On Hickory Drive, Mississauga

Peel – Peel Regional Police in partnership with the assisting agencies held a news conference this afternoon to share the conclusions of the investigation into the explosion that occurred on June 28, 2016 on Hickory Drive in Mississauga.

“Today we are here with our partners, the Office of the Fire Marshall of Ontario and Mississauga Fire and Emergency Services to share with you the outcome of what has been a very comprehensive investigation. We hope this will provide some answers, and much needed closure to those most closely impacted by this tragic event” said Peel Regional Police Chief Jennifer Evans.


At 4:21 p.m. on June 28th, 2016, Peel Regional Police dispatchers began receiving complaints of an explosion which had occurred in the area of Dixie Road and Rathburn Road East in Mississauga. First Responders arrived on the scene within minutes of the explosion, and began the process of evacuating the immediate area, providing assistance to victims and closing off access points in the neighbourhood.

The epicentre of the explosion was found to be the home which stood at 4201 Hickory Drive, which had been completely flattened by the explosion. Several adjacent homes were left with only half of their structures still standing and numerous other homes in the neighbourhood suffered serious damage.

Two people were killed that day both of whom lived within the residence on Hickory Drive which was the source of the explosion. The two victims were identified as Robert Nadler and Diane Page. Several others in the area suffered injuries that day and many residents were uprooted from their homes.

In the days that followed, a comprehensive investigation unfolded. A large-scale search of the scene was conducted which included a systematic removal of all the debris to preserve and collect evidence from the epicentre.

The investigation was conducted in collaboration with the Office of the Fire Marshall of Ontario, Mississauga Fire and Emergency Services, Peel Regional Paramedical Services, Enersource, Enbridge and the Technical Standards and Safety Authority. The Red Cross also provided community support.

Post-mortem examinations of Diane Page and of Robert Nadler were conducted. The cause of death for both was determined to be blunt force trauma, consistent with having been near the epicentre of the explosion.

Details of Investigation:

  • The explosion of 4201 Hickory Drive was as a result of natural gas inside the home. No evidence of any type of explosive has been located, and several witnesses reported smelling natural gas on properties adjoining the residence up to one and a half hours before the explosion.
  • Post-mortem examinations of Robert NADLER and Diane PAGE determined the cause of death to be massive blunt force trauma.
  • Investigators identified four possible scenarios which may have caused the explosion. Each scenario was thoroughly investigated. This investigation determined that the explosion was intentional and given that the supporting evidence ruled out accidental, double-murder or murder-suicide, investigators concluded that this was a double suicide.
  • The Office of the Fire Marshall of Ontario determined that there were two natural gas supply lines that were intentionally disconnected from the water heater within the residence.

In conjunction with our partners we plan to host a community forum sometime in the next two weeks. Once a date has been confirmed we will invite members of the community to attend.

November 29, 2016 – I have been advised that staff are in constant contact with the Fire Marshal’s office and Peel Region Police regarding the Hickory Drive explosion. The incident is still under investigation and no information has been release at this time.

I will provide an update as soon as one is available.


I want to express my deepest sympathies to the deceased resident and her family and friends as a result of this devastating explosion. As well my thoughts and prayers are with all residents impacted at this very difficult time.

I want to thank all the First Responders who attended immediately – Mississauga Fire Department, Peel Regional Police, Heavy Urban Search and Rescue Team, Animal Services and all Emergency Medical Services including Peel Paramedics. I was on site shortly after the explosion occurred and I am so proud of our First Responders not only for their immediate action but how they ensured all residents’ concerns were addressed and questions answered. I later attended Burnhamthorpe Community Centre where displaced residents were provided with essential services. Again, special thank you to the Region of Peel – Social Services, Salvation Army, Insurance Bureau of Canada and the Staff at Burnhamthorpe Community Centre for welcoming residents and again ensuring they were provided with anything they needed.

Going forward, the Office of the Fire Marshall Emergency Management Team is on site continuing their investigation. Peel Regional Police and City Building Officials are also on site ensuring both residents and buildings are safe.

Finally, I want to thank members of our community including the many churches, retailers and community groups who have come forward offering their assistance. At this time, no donations or personal supports are needed as all those residents who have been displaced have been taken care of.

I will continue to update my website as new information becomes available.
