Leth was born in Ottawa and lives in Halifax, Nova Scotia, and attended NSCAD University, studying photography. They dropped out before achieving their degree.

Leth worked at the Strange Adventures comic shop in Halifax, where they developed an interest in comics, and created promotional art for the shop. In 2010, they created their webcomic Kate or Die for their blog. Kate or Die eventually became a bi-weekly column on Comics Alliance. They cited fellow Nova Scotia writer Kate Beaton as an influence, "...this person who was putting all this stuff out there, and no real formal art school training, but was doing really well with her work." Leth also contributed to the webcomics Locke & Key: Guide to the Known Keys and The Strange Talent of Luther Strode, and the anthology, Womanthologoy: Heroic. They later contributed to the Smut Peddler anthology in 2012. Leth's Adventure Time fan art on their Tumblr page attracted the attention of BOOM! Studios, publishers of the comic based on the television show. They were hired to do covers, a short story, and a graphic novel, Adventure Time: Seeing Red, which entered The New York Times Best Seller list in April 2014. They also were a co-writer and co-artist for issue 3 of Adventure Time with Fionna and Cake, Adventure Time: Bitter Sweets, and Adventure Time: The Four Castles. In 2013, Leth organized The Valkyries, a group of women who work in comics retail. In 2017, Leth described the group as "great for creating a community" and equivalent to a union. The group was disbanded in 2018, largely related to accusations that the group failed to adequately represent the concerns of women of color. In 2014, Leth wrote for Jim Henson's Fraggle Rock: Journey to the Everspring, and Edward Scissorhands In 2015, Leth worked with Joe Quinones to pitch Batman ’89 as a comic series, but DC Comics rejected it. In 2015, Leth wrote another comic for Boom!, Power Up, and wrote six issues of Vampirella for Dynamite Entertainment. Leth was co-host for Less Than Live with Kate or Die, a bi-weekly comics podcast which last aired in 2016. Leth collaborated with the podcast Welcome to Night Vale and wrote stories for the Lumberjanes comic for Boom!. In 2018, Lumberjanes, the comic to which Leth contributed along with 5 other creators, was nominated for a GLAAD Media Award. They also worked on Transformers: Galaxies, an anthology comic book series by IDW Publishing which is a spin-off to 2019's Transformers comic book, which began on September 25, 2019 and concluded on December 30, 2020. For Marvel they contributed to Secret Wars, Too, a comedic anthology, and Patsy Walker, A.K.A. Hellcat!, for 17 issues. In 2016, Leth wrote for the graphic novel, School Spirit. From October 2016 to February 2017, they contributed to issues 1-5 of Spell on Wheels, co-writing with Megan Levens. Leth was also the cover artist for various webcomics. This included Adventure Time: Marceline and the Scream Queens #5 in 2012, The Midas Flesh #3 in 2013, Littlest Pet Shop #2 and Lumberjanes #1 in 2014, and Swords of Sorrow. Additionally, they were a variant cover artist of Sex Criminals #12. In 2020, Leth announced they had signed a deal with Simon and Schuster to produce a graphic novel entitled Mall Goth, released in September 2023.
