Experts combing through the home have described the explosives as pipe bombs and improvised explosive devices, Butler said Tuesday night.
BARRIE, Ont. — Police in Barrie, Ont., say they have discovered 80 explosive devices so far in a search of a home where two men were arrested last week in connection with a 1978 homicide.

About 60 neighbours were evacuated from nearby residences last Thursday after police found explosives and unknown chemicals in the home.
The residents are expected to be out of their homes for the rest of this week and Const. Angela Butler said police have no idea when they will be able to give the all-clear.
Investigators released photographs Tuesday of some of the devices and weapons found in the home, and of a basement room filled with boxes and jugs of chemicals.
