Deputy Commissioner and Interim Commissioner

In December 2013, Blair was named Deputy Commissioner and Provincial Commander of Traffic Safety and Operational Support.^[6] After the retirement of Commissioner Hawkes in November 2018, Blair became the Interim Commissioner. Blair along with Ron Taverner was a candidate for the permanent job appointment as OPP Commissioner.

After the committee's selection of Ron Taverner as the new OPP Commissioner, Blair submitted a request for the Ontario Ombudsman to investigate concerns regarding the appointment of Ron Taverner as the new OPP Commissioner. Deputy Commissioner (Field Operations) Gary J. Couture was then appointed as the Interim Commissioner. He assumed that role on December 17, 2018, with Blair returning to his previous position as Deputy Commissioner and Provincial Commander for Traffic Safety and Operational Support.^[7]

Blair, currently in the position of Deputy Commissioner of the OPP retained controversial, human rights lawyer, Julian Falconer to notify the Premier of his intent to sue based on remarks which Blair feels impugn his character. The remarks relate to Brad Blair's possible failure to maintain the confidentiality of information he obtained as OPP Commissioner, said confidentiality being a legal obligation of all employees of the Province.

On March 4, 2019, the Conservative government of Doug Ford relieved Blair of his position. Blair was fired for releasing confidential OPP information in a letter to the ombudsman, a breach of his oath as the force's deputy commissioner. This is all amid a number of controversies related to Ford's actions, including the appointment of Ford's long-time friend Ron Taverner as OPP Commissioner and the procurement of a specially-appointed vehicle^[8] for Ford's use. On September 13, 2019, Blair has filed a $15-million lawsuit for wrongful termination against Premier Doug Ford and calls for public inquiry.^[9][10]
