WOODSTOCK, Ont. - The Ontario Fire Marshal's Office continues to seek the cause of an explosion and fire in Woodstock that killed two residents and left dozens homeless.

But they are now finished with the scene of the fire and have turned it over to an insurance company.

Investigators will continue to examine a number of items taken from the scene that will hopefully lead them to the cause.

The timing of the final report from the fire marshal isn't known.

Woodstock Mayor Pat Sobeski says the city will hold a meeting next week to review how the city reacted.
