The 24-year-old pleaded guilty to robbery with intimidation for the theft from the MacDonald Avenue cannabis shop on July 25.
Vary, who is in custody, will be back in court June 4 for sentencing.
Ontario Court Justice Melanie Dunn heard two men, armed with a crowbar and a tire iron, entered the Temple Medicinal marijuana dispensary at 6:45 p.m..
Their faces were covered, and they banged the crowbar and tire iron on a counter as they forced an employee to put approximately three pounds of marijuana in a bag, prosecutor Robert Skeggs said.
The pair fled in a vehicle and the licence plate was noted.
"The entire robbery and the flight in the car was caught on video," the assistant Crown attorney told the court.
The police investigation discovered that Vary was one of the people involved in the robbery.
At the request of defence counsel Lindsay Marshall, a pre-sentence report will be prepared for her client's next court appearance.
Vary was arrested on Aug. 9 on outstanding warrants for multiple offences, including numerous theft and firearm charges.
