Three Pines was canceled primarily because its three major production companies could not come to an agreement regarding the development of a second season.
The Prime Video detective series concluded after its first season, with no renewal for subsequent installments. This decision stemmed directly from the inability of the key production entities involved in the show to secure a consensus and agreement for its continued creation. The challenges in aligning the visions and terms of these companies proved to be the decisive factor, ultimately preventing the series from being greenlit for further installments. Based on di Girolamo's Instagram post, the lack of agreement among these major production companies was the reason the second season was not approved.
