Lina Dabit joined the RCMP in 1994 and started her career in British Columbia where she spent 13 years posted to detachments up and down eastern Vancouver Island. She was lucky for the opportunity to work a variety of duties ranging from uniform patrol, drug section, major crime, intelligence, border integrity, and running a police boat while working solo in the Gulf Islands.

After transferring to Ontario in 2008, she focused on organized crime and national security, and as an Investigative Interviewing Subject Matter Expert, she went on to establish the RCMP interview team in Ontario.

She was commissioned to Inspector in 2017 and became the commander of the Air Marshal Toronto Field Unit. In 2021, she was selected to lead the Cybercrime Investigative Team in Ontario. She is currently working to establish an innovative operational Cyber hub focused on collaboration between federal, international and private sector partnerships.
