Meer is a member of the Canadian Comedy Award-winning improv troupe Die-Nasty and stars in the CBC sketch comedy radio program "The Irrelevant Show".
He also provided additional voices for various older Bioware games such as Baldur's Gate II, Jade Empire, Neverwinter Nights, along with more recent games such as Dragon Age. In Origins, Meer provided the voice for the male Warden's ''violent voice'' for the human/elf mid-combat quips and efforts, and voiced all of The Disciples--sentient Darkspawn who can talk and have free-will--in the expansion to Origins, Awakening.
While across the Mass Effect series Mark is most recognisable as the male Commander Shepard, he also voiced all of the Vorcha, Hanar (including Blasto), and many of the Volus encountered across the series.
