The arrests were made during two campaigns, called Project Karma and Project Calamity, that began in June.

Project Karma, which ran until the end of November and targeted street gangs and “brazen” firearms violence, resulted in 14 arrests, 137 charges laid and four firearms as well as and drugs and $5,000 seized.

Project Calamity, which ran until August, targeted people in the drug trade who were suspected of having access to or using firearms to commit offences.

Police say 13 people were arrested, 117 counts of charges laid and three guns seized as a result of that campaign.

They also say they seized more than 400 rounds of ammunition, drugs and $45,000 in Canadian and U.S. cash.
