Portrayed by Missy Peregrym

Andrea "Andy" McNally is one of the series seven protagonists, and the leading out of the other six. She is driven by the desire to do the right thing even if it means not following procedure. Her father, Tommy McNally, was formerly a homicide detective before he burned out. As a result, McNally carries her father's baggage, trying to prove herself. Her mother, Claire, is a social services worker who abandoned them when Andy was a teenager. She studied Sociology/Psychology before becoming a cop and she was an A student.

McNally was assigned to Oliver Shaw, who was mentored by her father when he was a rookie. Her first day begins disastrously; she was left to pursue two suspects on foot on her own as she had forgotten to turn her radio on and arrests them for drug possession, only to find out that one of them, Sam Swarek, was actually an undercover cop from her division and was two weeks away from a potential bust of a distribution ring – this was the premise for her love-hate relationship with him when he was assigned as her training officer. When Shaw is promoted to Acting Staff Sergeant in season 5, she volunteers to take his place as a training officer. Like her first day as a rookie, her first day as a training officer also ends disastrously when her rookie Duncan Moore contaminated the crime scene and offended a grieving widow when his cellphone started ringing while McNally was speaking with her.

After meeting in the pilot episode, McNally begins a relationship with homicide detective Luke Callaghan, and the two move in together at the end of season 1, although she previously kissed and almost had sex with Swarek, her training officer, before walking out on him, something that leaves them in discomfort for several episodes. She later becomes engaged to Callaghan but breaks up with him after he slept with his ex-girlfriend, Detective Jo Rosati. She finally admits that she has feelings for Swarek, but he has already left on an undercover mission. The last three episodes of season 2 show viewers the beginning of Swarek and McNally's relationship, even though he is undercover, which leads them both to suspension for "conduct unbecoming" when they are discovered. In the beginning of season 3, McNally returns from a trip after her three months' suspension and gets her job back as well as restarting her relationship with Swarek. When her mother suddenly appears in her life due to a work case, she decides to let her back in after she asked for a second chance. After Detective Barber's death, Swarek breaks up with her, which causes a lot of pain for McNally. After a month and a half, and in a life-threatening situation when she is holding a grenade, Swarek says to her that he loves her and then he tries to get her back. Then Detective Callaghan asks her to participate in a task force, which will keep her isolated and away from 15 Division during the mission. She accepts but has to leave immediately, which leaves Swarek drinking at the Penny (the local bar) while waiting for her. In the first episode of season 4, when she returns, she finds out he has been dating Officer Marlo Cruz while she was gone. Later on, Nick confesses his feelings for McNally, and the two embark on a new relationship. When Sam gets shot in the season 4 finale, she goes in the ambulance with Sam, and then confesses that she still loves him. It is shown in season 5 that the two are together again. At the end of season 5, McNally is caught in a bomb attack at the station, but escapes unharmed. In the season 6 episode "Home Run", Swarek proposes to her on a boating trip and she happily accepts. They marry in the season finale, with her best friend Traci serving as the maid of honor.

Dov Epstein is one of the series seven protagonists. Described as the "dork" of the batch of rookies assigned to 15 Division, he was a sickly asthmatic kid (he has been seen using his inhaler a number of times in the first two seasons) who watched reruns of Starsky and Hutch. His parents were "hippies", but his grandmother paid for him to have a private education.

He is often shown to be overeager to get involved in everything even when it is not necessary for him to do so, much to the chagrin of his more senior colleagues. This characteristic has gotten him into trouble many times, so much so he has been told to "slow it down". However, in season 2, Epstein's desire to be heavily involved enables him to save a man's life. He is Chris Diaz's best friend and roommate, and later Gail's roommate as well when she moves in with them. In season 2, he meets and becomes involved with Sue, a bomb technician from ETF, whom he always tries to impress, thinking he does not deserve her. They break up when he develops feelings for Crystal, the sister of the boy he shot and killed. In season 4 he has a one-night stand with Chloe Price, a woman he met in a bar and later finds out to be Frank's god-daughter as well as 15 Division's latest officer. By the middle of the season, however, the two of them have started a relationship. When Chloe is shot on the job, Epstein finds out that she is still married to an officer from her old division, Wes. He forgives her for this, but after he discovers that Wes kissed her and she hid the evidence from him, he breaks up with her, much to Chloe's dismay.

Despite this seemingly good trait, it makes him unable to take initiative. He was brought up in a small black-and-white town. He becomes involved in a relationship with Gail Peck until he is forced to notify the authorities of corruption that Peck's brother's partner was involved in. This temporarily costs him the relationship with Peck. However, the two reconcile and are seen happily together in the beginning of season 2.

Epaulette No.	6114

Portrayed by Ben Bass

Sam Swarek is a detective and one of the series seven protagonists. He is known to his superiors as a "rogue cop" because he prefers to follow his instincts instead of the book. Formerly an undercover officer working on a money laundering-cum-drug trafficking operation, his cover was exposed when McNally arrested him, believing him to be a suspect in a murder case. He returns to 15 Division as a training officer, awaiting a position to open up in Guns and Gangs. In season 4 he is promoted to detective.

Swarek is known to shut down and bottle up his emotions, instead taking it out by punching inanimate objects, especially his locker. From Season 4 onwards, he begins opening up to Andy and his long-time friend Oliver Shaw, who are the only people he has confided in. He is extremely loyal to his friends and put his career on the line several times to protect them.

In the season 1 episode "Hot and Bothered", Andy, upset and confused, goes to see him at night and almost sleeps with him. This makes their relationship awkward afterward, but the two talk and make amends later. Although McNally is his love interest, he insists that their relationship is strictly professional. But in season 2, there still might be hope for McNally and him because of McNally's fiance Luke Callaghan cheating on her. During the end of season's 2 "Best Laid Plans", he went back into undercover operations before he had the chance to become romantically involved with McNally. However, they meet in the following episode and finally hook up. After getting suspended, he asks Andy to have a real relationship, but she leaves town to keep her job, since one of the terms of the suspension was for Swarek and McNally to not see each other, which leaves him disoriented. In the beginning of season 3, Andy convinces him to restart the relationship, although he wants to take it slow. When Andy's mother reappears in her life, he investigates her, and we see that he doesn't like or trust Claire because he blames her for Andy's pain. When Detective Barber dies, he goes into a dark place and starts to question Andy's instincts as a cop. He then wonders how much he will sacrifice for their relationship, so he breaks up with her saying that he cannot take it anymore. Everyone tells him how foolish he is for what he's done, but he has already noticed. When he sees Andy terrified and holding a grenade, he confesses his love for her. Then he tries to convince her that breaking up was a mistake, that he will do anything to make it up to her, but she is hurt and not sure he means it. He asks her for drinks, but he is left waiting as she is already gone for the task force without talking to him. In season 4, he becomes detective and has been dating Officer Marlo Cruz. He was shot by Kevin Ford in the last episode of season 4, but recovers. In season 5, he rekindles his relationship with McNally, and later proposes to her in mid-season 6. On the first episode of season 6, Marlo confesses to him that she's pregnant, and this causes a strain in his and Andy's relationship for some time. He and Oliver Shaw begin to have suspicions about corruption within the police force during season 5 and 6, which is confirmed when Police Commissioner Santana and Steve Peck gets arrested. In the season 6 finale, Swarek marries McNally at a small church wedding with their colleagues and both their fathers present. Shaw, one of his few close friends, was his best man. Swarek owns a goldendoodle named Boo Radley, whom he bought for McNally (as he promised after they previously broken up) before they get married.

For most of the first four seasons, Swarek is largely an enigma. He never spoke of his family or opens up to anyone, despite being popular with his colleagues. In "Big Nickel", he tells McNally that his sister Sarah was attacked when he was a kid, which was why he became a cop. When he was shot in the season 4 finale, it is revealed that he had no next of kin listed and it took Nick Collins several hours to track down Sarah (Robin Brûlé), who reveals that she has not spoken to or seen her brother in years. It is not until season 5 that Swarek's painful childhood is fully revealed, but only after McNally's persistent questioning. His father Jay Swarek (Nicholas Campbell) was an abusive alcoholic who was "in and out of prisons all our lives" and used to hit his wife and two children to the point where the police have been called. Sarah, whom Sam affectionately calls "Square", still visits their father in prison but Sam continuously refused to as he had lingering fears that he would one day be like his father. As a result, the siblings drifted apart over the years, only communicating sporadically through text messaging. Jay is currently imprisoned at Milburn Penitentiary. He was present at Sam's wedding, albeit uninvited, but father and son call an uneasy truce and he tells Sam to "thank your lucky stars you didn't end up like me".

Oliver Shaw is one of the rookies' training officers and a 20-year veteran (as of season 6) of the police force. He was introduced in the pilot as the training officer of Andy McNally, a fresh academy graduate and daughter of his own former training officer Tommy McNally.

Shaw is the kind of cop who doesn’t go looking for trouble but doesn't shy away from it when it finds him. Despite being their superior, he takes care of the rookies and genuinely cares for them. He appears too laid back and is often seen eating a burger or sandwich in his car while on patrol waiting for a call but reveals that he did it so that his rookie would have the chance to take a breather and not rush into things. During off-hours he is usually seen hanging out with his colleagues, either Swarek or one of the rookies. He is close friends with Swarek, whom he calls "brother", and would serve as best man at Swarek and McNally's wedding.

In season 1, Shaw is portrayed as one of the few older police officers with a functional marriage and family, having a wife and three daughters, but it goes down the drain when his wife finds out he visited a strip club and kicked him out of the house. He and his wife had been on and off before he realizes that she was in love with someone else. He then files for divorce and moves out. He is dating a witch named Celery, played by Emily Hampshire. In season 5, he is promoted to staff sergeant after Frank Best was removed in light of Swarek's shooting and because Ford managed to elude security and enter the premises with a weapon. internal affairs needed a scapegoat and Best stepped down as a result. A self-described "street cop", he has expressed discontent on numerous occasions with remaining behind the desk during a crisis. He is still a very hands-on cop and continues to be a mentor and confidant for his officers; for example, he personally led the search for a young autistic boy who had wandered off.

Luke Callaghan

Portrayed by Eric Johnson

Luke Callaghan is a homicide detective at 15 Division. Tireless and exceedingly charming, he sometimes butts heads with Swarek over the latter's penchant for bending the rules during investigations. He was involved in a relationship with McNally, despite Swarek warning her that Callaghan had a reputation for dating one rookie a year, until he cheated on her with his ex-girlfriend, Jo Rosati. McNally ends the relationship, but Luke wants her back, and the fallout causes Jo Rosati to leave 15 Division. He is heartbroken but eventually accepts that Andy doesn't want him back. This is particularly seen when he discovers that Andy and Sam had been seeing each other while Sam was undercover. He is gone half of the third season due to a task force mission. He comes back after Gail's kidnapping. At the end of the season, he asks Andy and Nick to participate in the task force with him.

Despite his reputation as a charming "ladies' man", he is dedicated to his work.

Detective Barber died in episode 9 of season 3 due to a fatal stab wound to the abdomen while trying to solve Peck's kidnapping. Barber's death would affect 15 Division as a grief-stricken Nash struggles to move on while Swarek shuts down emotionally, leading to his break-up with McNally.

Noelle Williams

Melanie Nicholls-King portrays Noelle Williams. Another training officer and veteran of the police force, she hoped to become head of her police platoon but was beaten out by Frank Best.

She was caught by Traci who subsequently helped her. In episode 9 of season 2, she and Frank Best kiss, embarking on a relationship. It is revealed in the finale of season 2 that Noelle is pregnant with Frank Best's child and in the beginning of the third season, she is keeping it a secret. In episode 9 of season 3, she goes into labour a month early and delivers a healthy baby girl named Olivia. In season 4, she becomes engaged to Staff Sergeant Frank Best after he proposes to her following a faked homicide involving officers Peck and Epstein.

She is later convinced to go through with the wedding, and has since been optimistic about her recovery.
