Main Officers •
Missy Peregrym portrays Andrea "Andy" Grace McNally, the series protagonist. 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. Andy is the most positive person on the job—because she knows first-hand where the job can take you, and she does not want to go there. 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. At the beginning of the series she begins a relationship with homicide detective Luke Callaghan, and the two move in together at the end of season 1, although she and her training officer, Sam Swarek, have a palpable chemistry. After having shot her first person on the job, she is confused and runs to him, intending to sleep with him in order to stop thinking. Before it progresses too far, she walks 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 sleeps with his ex-girlfriend, Detective Jo Rosati. She finally admits that she has feelings for Swarek, but by the time she is ready to tell him 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, Andy 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 asks for a second chance. After Detective Barber's death, Swarek breaks up with her, which causes a lot of pain for Andy. 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. But for Andy, it is too little, too late. Then Detective Callaghan asks her to participate in a task force, which will keep her isolated and away from 15 Division for an extended period of time. 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. She is a bit competitive but eventually decides to move on. She becomes closer to Nick Collins, who was her partner undercover, resulting in the two of them beginning 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, Andy is caught in a bomb attack at the station, but escapes unharmed. In Season 6, when it is revealed that Marlo is pregnant with Sam's child, it causes tension between Andy and Sam, with Andy feeling left out. However, their relationship remains strong and they marry at the end of Season 6. •
Charlotte Sullivan portrays Gail Peck. She spent a few years as a half-goth. Underneath her caustic exterior, Gail is vulnerable and feels lonely. Because she is the daughter of high-ranking officials in the police force she is often seen by others as getting preferential treatment. Her mother is a superintendent, her father is an inspector, her brother a successful narcotics detective, and her godfather is the chief of police. Because of this, she feels the need to prove to herself and others that she can do the job without help, which further isolates her. In Season 1, she develops a relationship with Chris Diaz. However, the two break up in season 2 because Chris believes that she likes Dov but none of them are willing to clarify how they really feel. In Season 3, it is revealed that she was previously engaged to the new rookie, Nick Collins, with whom she begins a new relationship. Later, she is kidnapped by a cab driver after working undercover as an escort and is rescued, but at the expense of Detective Jerry Barber's life. When she takes the fall for a shooting in the 15 Division, her job is put on the line, but she does not lose it under the condition that she be treated as a new rookie. Gail ends up isolating herself from her friends due to the way she treats Chloe. Seeing how close Nick and Andy had gotten since their undercover operation, she becomes jealous and cheats on Nick with a detective who worked with him and Andy during their sting operation. As a result, she and Nick break up. Later in season 4, she ends up meeting and befriending Holly, a forensic specialist, and lesbian. The two share a brief kiss in the coat closet at Frank and Noelle's wedding and eventually begin a tentative relationship. At the end of season 5, Gail and Holly break up and Gail decides to adopt Sophie, the orphaned daughter of a woman killed in a case Gail worked on. •
Travis Milne portrays Chris Diaz. He is often seen as taking the "by the book" approach. He believes in the chain of command, following orders, doing the right thing and above all, he believes in defending the weak. Despite this seemingly good trait, it makes him unable to take initiative. 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. Their relationship ends when he accuses her and Dov of sneaking around behind his back. He eventually makes amends with Dov, but not with Gail. After a while, he realizes that he still has feelings for Gail, only to discover that she is now with Nick Collins. He finds out that his ex-girlfriend, Denise, had his child without telling him but accepts his role as a father and begins making family-centred decisions. He considers a transfer to
Timmins at the end of the third season because Denise does not want to live in the city and he still wishes to remain close to his son, Christian. In the fifth episode of season 4, Chris accepts his transfer to Timmins early and leaves, only saying goodbye to Oliver. However, he reappears in the ninth episode of season 4 when he comes to visit for the long weekend with Denise and Christian. Christian is later kidnapped while under the care of Andy and Nick, and it is later to be revealed that the kidnapper is his biological father, Gene McKenzie. In episode 10, Chris transfers back to 15 Division. He is no longer with Denise, but struggles to be so far from his son. Dov later discovers that Chris is becoming addicted to cocaine, which results in a fallout between the two. However, Chris takes some time off to recover and things are made right again with Dov. In Season 6, he is in affair with Jamie, a recovering alcoholic, who is revealed to be the wife of Inspector Jarvis. Chris tries numerous times to end things with her but finds himself incapable of doing so. At the end of Season 6, it is revealed that Jarvis had known about the affair but that he himself had a girlfriend since he and his wife were getting divorced. •
Peter Mooney portrays Nick Collins. He appears for first time in season 3. He is a former soldier who served for four years, including a tour in Afghanistan, before becoming a cop. Before the series began he was in a relationship with Gail Peck, and they were ready to marry in Las Vegas before he enlisted. When he first comes to 15 Division they start a new relationship, albeit after much coaxing on his part. His military training and experience is often considered as an asset by his colleagues. In the season 3 finale he is selected as the other officer to participate in Callaghan's task force, resulting in his developing feelings for Andy. He eventually breaks up with Gail when he finds out that she slept with someone else. He tells
Andy on the night of Frank and Noelle's wedding that he has romantic feelings for her, but Andy needs time to sort things out. He and Andy begin a relationship shortly after. However, Nick knows subconsciously that Andy is still in love with Sam, which is acknowledged when the latter is shot at the end of Season 4. He tells Andy to go see Sam at the hospital, showing that he knows that she can never let go of Sam. In Season 5 they are no longer together but eventually go back to being good friends. In Season 6 Nick meets Officer Juliet Ward who, unbeknownst to him, is an undercover officer for Internal Affairs. He expresses an immediate interest in her, but Ward tries not to get close to any of the officers that she is investigating. However, the two eventually give in to their feelings for each other and begin a relationship. When it comes to light that she is investigating their division, Nick breaks it off with her, feeling betrayed. At the end of Season 6, Ward is on her way to Vancouver when Nick stops her to tell her that he wants to go with her, indicating that he has forgiven her. •
Priscilla Faia portrays Chloe Price. She appears for the first time in season 4, when she is first introduced as a
one-night stand of Dov's and then later revealed to be Frank's goddaughter and the newest rookie to be transferred to 15 Division. She is talkative and bubbly, which sometimes annoys the other rookies. However, she shows herself to be a competent officer. She and Dov embark on a relationship, until Dov finds out that she is married to Wes, an officer from her old division. It does not help that he finds out about Wes by meeting Wes himself while Chloe is in a coma and unable to explain anything. When Chloe wakes up and recovers, she assures Dov that she and Wes had not been together for a long time and that they were getting divorced. However, she kisses Wes one day and Dov breaks up with her. She spends the season trying to win him back but Dov responds coldly. At the very end of Season 6, Dov has an outburst and their problems are finally out in the open. They kiss and get back together.
Detectives •
Gregory Smith portrays Dov Epstein. He was a sickly asthmatic kid who watched reruns of
Starsky and Hutch while in bed and his older brother, Adam, killed himself, something that Dov still does not understand. 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. 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. They eventually get back together. At the end of season 6 he is promoted to detective. •
Ben Bass portrays Samuel "Sam" Jay Swarek. He is known for following his instincts rather than following the book and is thus labeled as a rogue cop by his frustrated superiors. Formerly an undercover officer working on a money laundering operation, his cover is exposed when McNally arrests him in the series premiere, believing him to be a suspect in a murder case. He returns to 15 Division as a training officer for the rookies, awaiting a position to open up in Guns and Gangs. In episode 7 (Hot and Bothered) of season 1, 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 fiancé Luke Callaghan cheating on her. During episode 10 (Best Laid Plans) of season 2, 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. He has a sister, Sarah, who was attacked as a kid, and that is why he became a cop. 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 in the last episode of season 4, but recovers. It is later revealed in season 5 that his father, Jay Swarek, is an inmate at Millburn Penitentiary, and was in and out of his childhood.
