Mystery vibration rattles Saskatoon homeowners while manufacturing plant hunts for cause

Sylvain Quirion describes it as a "pulsating hum" that rattles his oven, his barbecue, silverware and toolbox in his garage.

Carol Zentler says the "terrible vibrations" are cracking her walls, stopping clocks and shaking her china cabinet, while Gary Poleschuk calls it simply "the vibration."

The trio live side by side in bungalows on the 1700 block of First Avenue North in Saskatoon. For the past two years, they and other neighbours on the block say they've lived with a mysterious vibration that comes at different hours of the day, evening and middle of the night.

The residents say it all began when ABC Manufacturing built a block-long warehouse that looms over their homes from across the back alley.

"It's been two years now and, yeah, ever since they moved in we've just been getting vibrations all the time," said Quirion.

Both Zentner and Poleschuk have lived in their homes for more than three decades.

"I turn a lot of music up, it's just stressful for me because it's a constant low hum. You can constantly feel and hear it in this house," said Zentner.

Matt Grazier, director of the city's Community Standards Department, wrote in an email that the bylaw compliance team has completed several inspections in the area, both inside the building and at some of the nearby residences, "and have not observed in-person any instance of the issue."

Grazier wrote that "the case is not closed — we have an open file on this property and are continuing to follow up with some of the residents in the area to hopefully pinpoint what may be causing the noise issue. Complaints do coincide with construction of the new ABC building but we have not seen any firsthand evidence to support the building is causing the noise."

Both Quirion and Zentner take a dim view of the action taken by the city. Zentner has collected a stack of correspondence from a raft of civic officials and councillors, adding that she has yet to get a satisfactory explanation.

Quirion offers a blunt take on the experience. "The only thing we ever get from the city is not very much," he said.

"They don't really do a whole lot about it."

ABC Manufacturing makes ventilation systems for mining and aviation companies. In 2020, it proposed a manufacturing and warehouse project between the 1700 blocks of Quebec Avenue and First Avenue North.

It's been in the neighbourhood since 1995 and the 2,500-square-metre "Plant 3" is the latest building in its complex.
