The oldest accused in Project South is Donald Kirkland 62, of Toronto, who faces multiple charges for trafficking oxycodone, acid, psilocybin, cocaine, GHB, MDMA and methamphetamine.

The two youths, and Almar Heath, 28, of Toronto, were arrested after York police say they foiled a murder bid at a home in Markham on June 20.

Court records show that Heath is also facing murder conspiracy charges after a man in a mask appeared at a Markham home on June 28.

The would-be hit team’s vehicle collided with a marked York police cruiser that was stationed at the home, York police said in a prepared statement.

The alleged hit team found the home of their target after Toronto police constable Timothy Barnhardt unlawfully accessed a police database, performing a query that produced confidential information, York police said.

York investigators say the June incident at the Markham home alerted them to numerous unlawful police data base queries by Toronto police officers, which were used to plan an extortion, commercial robberies and shootings.

Investigators allege that the confidential information gleaned from the queries was shared with Brian Da Costa, 43, of Toronto, Elwyn Satanowsky, 34, of Richmond Hill and others, who police say are both “known to various criminal networks.”

Da Costa was on a release order requiring he remain in his home when he was charged on Tuesday. The original charges were for possession of fentanyl for purposes of trafficking and possession of cannabis for the purpose of distributing and exporting. He remains in custody.

Other civilians charged in Project South include Kaejean Doman, 23, of Innisfil, who was arrested at a shooting scene in Vaughan in September.

York police accuse Doman of being in possession of a firearm that police say was illegally smuggled into Canada and connected to at least eight shootings across southern Ontario.

Police accuse Doman, along with Median Jackson, 32, of Mississauga and Devonte Barker Campbell, 31, of Toronto, of accessing confidential information obtained by Barnhardt and of recruiting others to commit crimes.

York police say they also uncovered a plan, led by Da Costa, in which Toronto police officers planned to support illegal cannabis dispensaries by accepting bribes to obstruct any possible enforcement action to be taken at those locations.

Investigators working on Project South also arrested numerous suspects who face charges for the commercial drug trafficking of cocaine, methamphetamine, illicit cannabis, fentanyl, heroin and oxycodone.
