A Burlington gardener getting more than he bargained for last weekend, when he dug up a World War II era hand grenade.
Halton police were immediately called in and their explosives unit determined it was an MK II grenade.
Police turned the explosive over to the military who identified it as a standard issue practice grenade used in training exercises.
Police tracked down the previous homeowners who had lived at the house for 30 years and they said they never buried the grenade.
