At 3:36 the Guelph Mercury posted a news update to say that there was a new fire being fought by the department this time on Manitoba Street in the Ward.
The second fire drew trucks and crew away from the down town fire.
According to the Fountain Pen
the second fire started in the basement and the fire chief does not regard it as suspicious. The photo has a burnt out bed in the foreground, and driving past the site a day later, the burnt out bed was still there, so smoking in bed may have been the cause of that fire.
