The Edmonton Police Service is also a member of the Alberta Law Enforcement Response Teams.

Aside from dealing with law enforcement issues, Campbell was also Edmonton's health and licence inspector.

[11] The Mounties resumed the maintenance of law and order in the City and the Edmonton Police Department was founded to stay in 1894.

Former WWI ace Wop May flew an airplane to assist the successful pursuit and capture of John Larsen, murderer of Edmonton constable William Nixon.

In 1986 after years of stagnant and declining wages and eroded provincial labour conditions and laws, local millionaire and owner of the Edmonton Oilers and the Gainers meatpacking plant Peter Pocklington provoked a massive strike after threatening to cut wages from $13.00 an hour to $7.00 an hour, among other attacks on benefits and conditions.

In the first month of the strike, Edmonton Police deployed 1/3 of their force to the Gainers picket line, including their riot squad for the first time.

As described by Dave Werlin, president of the Alberta Federation of Labour at the time, "If the police had never shown their faces at the picket lines, no one would have tried to run buses through, there would have been no violence or arrest".

[16] In 2021 after a two-year delay related to roof collapse and other structural and mechanical failures, a new Northwest Edmonton Police Service Campus was opened at 18440-127 Street NW.

[17] On December 15, 2023, the EPS notified social service and homeless support organizations in the Edmonton downtown core of their plan to remove 134 tents and structures at what they deemed to be 'eight high-risk encampments' over 5 days, right before Christmas.

The planned operation would be one of the largest and fastest encampment sweeps in Edmonton's history, and would be carried out by police in conjunction with city employees.

An emergency court filing by lawyers working for the Coalition for Justice and Human Rights secured an interim injunction against the sweeps.

[21] At the last sweep on January 10 at Rowland Road encampment, as temperatures outside dipped to −30 °C, three people were arrested, including journalist Brandi Morin, camp elder Roy Cardinal, and Dene and Blackfoot drummer, observer, and activist Teyen Bohnsack.

[23] One of the peace officers claiming obstruction of justice was Amber Maze, a former candidate for the Wildrose Party.

Almost none of the cases, whether investigated through internal disciplinary committees or through the Alberta Serious Incident Response Team (ASIRT) led to convictions or firings of allegedly offending officers.

[40] The Edmonton Police Service Pipe Band was formed in 1914, although it was immediately dissolved at the start of the First World War, with its musicians being transferred to the Canadian Expeditionary Force to join Princess Patricia's Canadian Light Infantry (PPCLI) and lead the regiment into battle.

The band was first invited to play at the PPCLI beating retreat ceremony in 1964 and then at the regimental trooping of the colour in 1967.

The first armoured vehicle obtained by EPS was a used Grizzly, donated to them in 2007 by the Department of National Defence.

Criticisms largely focused on context of the Cambli Black Wolf's purchase, which was made public during the Black Lives Matter movement, which brought to light issues and criticisms of police brutality across North America and the world.
