There are a couple of reasons why northwest residents have been hearing booming explosion sounds near the Spyhill Landfill.
On Friday night, many residents were awoken by the sounds of explosions.
Police were detonating an explosive device that shook windows in several communities.
Area Councillor Joe Magliocca says he’s talked with police and they will try to avoid the night-time blasts, unless there’s an emergency need to do so.
Meantime, over the past few months there have been other noise complaints, as air cannons have been used to scare away ravens and other birds to protect workers at the landfill.
The sound of those air cannons are within acceptable limits.
Magliocca says, as the city grows and more homes get closer to the landfill, the number of complaints have increased.
He’s hoping to hold a town hall for residents living near the landfill and with police to answer more questions.
