Gilbert Zylstra and his son Dwayne (right) survey the aftermath of a fire which destroyed a barn on their Sixth Line property. The barn had been standing on the Zylstra property since it was moved to the location from Brampton in 1948 to be used as a poultry laying operation.

No one was injured in the fire, and the cause is undetermined, however, a smoldering spark from metal grinding done by the property owner in the barn Saturday may have started the blaze, said a spokesperson for Halton Hills Fire Protection and Prevention Services. Greg Coman, whose home is several hundred feet in front of the barn said he was awakened by someone frantically banging on his front door at about 1:50 a.m. After being told the barn, which is owned by his neighbour Gilbert Zylstra, was on fire, he rushed out his back door to take a look, and found another passerby, a deaf man, standing on his back porch. He had typed, "I'm deaf, your barn is on fire," on his Blackberry and handed it to Coman's wife. See FIREBALL, pg. 3
