Waterloo Region police seized more than 60 guns – the majority of them long guns – 1,000 rounds of ammunition and several edged weapons from a Waterloo man on Saturday.
The guns, ammunition and knives were seized as part of an ongoing criminal harassment investigation, police said.
In a release, police said officers are permitted to take the guns and ammunition under a public safety warrant "when there are reasonable grounds that it is not in the public interest for that individual to have possession of weapons."
Police noted all the guns seized were legally owned.
