Barrie police Sgt. Tim Conroy told CBC News that he has never seen such a large collection of explosives in a single location.
“It’s a lot more than we would find in a year and to find them in one location is a bit disconcerting,” he said during a telephone interview on Sunday.
Police began searching the home on Thursday and have found explosive devices tucked away in hidden places while others were left out in the open.
Conroy said the devices, which vary in size, are built out of metal or plastic and are packed with explosive material and metal.
The explosives that have been removed from the home have been detonated.
In a separate interview on Sunday, Conroy said that police will likely remain at the scene for a "couple of more days" as they ensure that no more of the devices remain.
The process has been time-consuming, as officers have found the devices in number of locations inside the home.
"Some of these devices have been found in plain view, some have been found concealed, some have been found amongst other things that you would just find normally in your household," he said.
"So the officers have to be very, very careful as they are moving around and looking to determine where these devices might be."
'Not safe' for residents yet
Earlier Sunday, Conroy said that about 60 people have been forced from their homes as a result of the ongoing police investigation.
"Due to the number of explosive devices, it’s not safe for them to come home unfortunately," he said.
Conroy also confirmed that there are firearms inside the basement of the home, but said that police have not removed them from residence yet.
"Right now, the investigators are more concerned with ensuring that the house is safe for them to move around in, rather than going down to seize guns," he said.
Two men who lived in the Virgilwood Crescent are facing charges in connection with a homicide that occurred more than 30 years ago.
Donald Feldhoff, 54, has been charged with first-degree murder in the 1978 death of 26-year-old Michael Traynor.
His 75-year-old father, William, was charged as an accessory after the fact.
Police say Donald Feldhoff turned himself in on Wednesday, triggering the arrest of his father and the search of the house the pair lived in for decades.
