Tyler "Ty" Borden is Amy's husband with a troubled past.
As a child, Ty was abused by his stepfather Wade, and was arrested and sent to juvenile detention after attacking him when he was assaulting his mother, Lily Borden. For his probation, he was sent to Heartland to work. He soon began to enjoy his life there and decided to stay.
Jack treats Ty like a son and is very proud of him, especially after he earned his high school diploma and decides to become a vet.
Ty dated Kit Bailey, a local cowgirl, for a time before admitting his feelings for Amy. They dated for a time but eventually broke up due to a lack of trust. Later, while working with a pair of horses, Ty and Amy managed to talk things through, and they got back together. Ty buys a ring with plans to propose to Amy in the final episode of Season 5, after a motorbike accident with Jack, but after hearing how they should never "tie themselves down" from Amy, leaves the room and goes outside, thinking twice about proposing. After he leaves, his phone rings; Amy goes to answer it, and she finds the ring. In Season 6, after much miscommunication and bickering, Ty and Amy come to an agreement to wait to get married and Ty gets accepted to vet school. After a few episodes, Ty and Amy find themselves in the perfect moment while camping and he proposes to her; she accepts. In season 8, they get married. At the end of Season 9, Amy tells Ty that he's going to be a father.
In the beginning of season one, Ty Borden is a troubled and ill-tempered 17-year-old. He entered "juvie" at a young age after attacking his step-father, Wade, for abusing his mother. For his probation, Ty's probation officer, Clint Riley, made a deal with Marion Fleming that Ty could stay at Heartland Ranch and work there as a stable hand.
When Ty first arrives at Heartland he reves his truck and speeds past Amy Fleming while she is out riding with a friend, angering her. He informs her that he's looking for Marion Fleming, and Amy tells him that Marion was her mother and she had died.
Ty then meets Jack Bartlett, owner of Heartland Ranch and Amy's grandfather. He, at first, reluctantly agrees to let Ty stay and work at Heartland for the duration of his probation. Jack lets Ty stay in the room above the barn, the loft which Ty is none too thrilled about.
Ty often frustrates Jack when he begins working as a stable hand, often slacking off and giving attitude. Jack especially becomes upset when Ty goes to a party that Amy is also attending when he was supposed to be working.
When he arrives at the party, uninvited, Ty sees Amy's boyfriend Jesse Stanton grab her and, thinking that he is hurting her, proceeds to get into a fight with him. Amy leaves the party angry and Ty follows. Ty apologizes and offers her ride home, to which Amy originally rejects but eventually agrees. Jack gets angry with Ty, and Ty then decides to leave.
In the second episode, Ty builds a track for Amy to practice her jumping, beginning to show a softer side to him.
Throughout the season, Ty proves that he is not the same troubled teen he once was, and constantly helps Amy with Spartan (Amy's horse).
Ty and Amy become good friends and they both start developing feelings for each other.
Ty and Amy have many flirty moments where they both lean towards wanting more than friendship but ultimately not wanting things to change between them.
Ty becomes Amy's coach for an upcoming jumping competition in the last few episodes. This causes them to spend more and more time together leading to them kissing in the season finale. Although Ty wants to be with Amy, he leaves in the middle of the night to live with his estranged father, hoping to reconnect.
In the beginning of season two, Ty comes back from being with his dad; Amy is upset with him for leaving, bringing on tension between them. The new ranch hand named Caleb O'Dell has a thing for Amy, making Ty and Amy's relationship even more strained and complicated.
Ty can't find the right words to get her to trust him again and to prove that he's not going anywhere, making it difficult to bring their relationship back to where it was in season 1.
In episode 4, Ty finally tells Amy about his father and why he left. He tells her he should have called but was worried that the one thing he wanted to say she might not have wanted to hear anymore. As Ty is about to leave, Amy grabs his arm and kisses him.
Ty's dad comes to town causing a rift between him and Amy, as Ty pushes her away, worried about becoming like his dad. After his father leaves, Ty expresses his concerns; Amy pulls Ty outside and they kiss, but Ty stops and says that he doesn't want to hurt her. She says she is willing to risk that but he is not willing to.
Ty not wanting to hurt Amy begins a relationship with Kit Bailey but is not totally invested as he is in love with Amy.
In the finale of Season Two, Amy and Ty go to Jack's fishing cabin to save some starving horses. They eat dinner together and talk about the future. Ty is thinking of interning with Scott Cardinal at the Vet Clinic. Amy asks about their future and Ty says it is up to her. Ty becomes ill and Amy takes care of him. That night Amy dreams of everything they have been through so far. When she wakes up his fever is gone and he tells her she is beautiful. She looks outside and sees the Ghost Horse, who returns in later seasons during key points in Ty and Amy's relationship. They go outside and hug.
