Lexier expresses the concepts he has developed through sculptural means, using ready-mades or materials prepared using industrial processes.
This work embodies a number of themes that are central to Lexier's art practice: timelines; life span; mortality; and the ordering of things and their undoing.
In 2010, the Press of the Nova Scotia College of Art and Design published, I'm Thinking of a Number,[4] a 30-year survey which documents this aspect of his practice.
In keeping with Lexier's overall approach to artmaking, the work's emotional tone is muted, yet it dramatizes the universal fact of aging.
[7] This is true of his on-going series, A Minute of My Time (born 1995), in which scribbles the artist makes over the course of a minute are transformed in a variety of ways, including: factory-produced water-cut metal sculptures, etchings, custom minted coins,[8] lines sewn onto pieces of paper, spray-painted graffiti, and chalkboard drawings.
[10] In addition to working with McCormack, Lexier has collaborated with the Canadian poet, Christian Bök[11] and the Irish writer, Colm Tóibín.
In 2008, Lexier produced a project with Tóibín and the entire student body of Cawthra Park Secondary School.
Lexier is co-editor with Dan Lander of Sound By Artists, co-published by Art Metropole and Walter Phillips Gallery (1990).
