The Office of the Fire Marshal has wrapped up its investigation into the Victoria Common fire, but “unanswered questions” mean the file has been turned over to police.

“We have information now that would suggest there were suspicious circumstances,” Waterloo Regional Police spokesperson Olaf Heinzel said Thursday.

“We’re looking for anyone who saw any suspicious activity around the time of the fire to give us a call.È

It was Tuesday morning that fire broke out at the Victoria Common development, near St. Leger and Louisa streets in Kitchener’s north end.

The fire caused an estimated $5 million in damage, destroying two rows of townhouses.

Fire officials say five occupied units suffered significant damage, while the rest of the hardest-hit residences were still under construction.

They declined to offer specifics of what investigators found in the rubble before the OFM investigation wrapped up Wednesday night.

“It was determined that the investigation was going to be handed over to Waterloo Regional Police for further follow-up,” said Tom Ruggle, Kitchener’s chief fire prevention officer.

As the investigation continues, some signs of normalcy are returning to Victoria Common.

Jeremy Kuyvenhoven, a spokesperson for developer Losani Homes, says his company is working with insurance firms to determine which parts of the complex need to come down and which can be salvaged.

“We have some obstacles to jump through, with removal of burnt items and structures we need to assess,” he said.

Residents in units that weren’t heavily damaged might be able to return to their homes as soon as late in the day Thursday, Kuyvenhoven said.
