Family and education O'Connor was born in Pittsburgh, Pennsylvania, to Bob O'Connor and Judy Levine O'Connor. He is the youngest brother of Terrence O'Connor, a priest, and Heidy Garth. Bob represented District 5 as a member of Pittsburgh City Council from 1992 to 2003, including a four-year stint as council president; he was then elected Pittsburgh mayor in 2005, but six months after taking office in January 2006, he was diagnosed with a rare brain cancer and died seven months later. In his father's memory, Corey and his family established the Bob O'Connor Memorial Fund. To support the fund, they host the yearly "O'Connor Cookie Cruise" on the Gateway Clipper Fleet, which is attended by thousands.

He subsequently co-sponsored or supported gun reform legislation. He has also advocated nationally for stricter gun ordinances.

In 2022, O'Connor was nominated by Governor Tom Wolf and then confirmed by a Pennsylvania State Senate committee to become the next Allegheny County Controller, filling the vacancy left when Chelsa Wagner vacated the office on January 3, 2022, after being elected in 2021 to serve as a judge on the county's Court of Common Pleas. On July 10, 2022, O'Connor resigned as a member of city council and then was immediately sworn in as county controller. He was elected to a full term in 2023.

O'Connor's vacated city councilmember position was succeeded by Democrat Barbara Greenwood Warwick in a special election on November 8, 2022.
