Mike Miller steps in as Toronto Argonauts head coach after Dinwiddie’s exit

By Canadian Press on December 2, 2025.

TORONTO — Mike Miller is the next head coach of the Toronto Argonauts.

The Argos promoted Miller on Tuesday after he spent four seasons as Toronto’s quarterback coach.

Miller succeeds Ryan Dinwiddie, who left the Argonauts in a surprise move to become head coach and general manager of the Ottawa Redblacks on Nov. 5.

The 55-year-old Miller, from Pittsburgh, has extensive coaching experience, making stops in the NFL, CFL, XFL and Europe.

He served as the Arizona Cardinals’ offensive coordinator in 2011 and 2012, and then became offensive coordinator for the Montreal Alouettes in 2013.

Miller was hired as quarterback coach for the Argonauts in 2022, winning a Grey Cup that year and again in 2024.

Toronto finished with a 5-13 record last season, missing the playoffs for the first time in five years under Dinwiddie. He guided the Argos to two Grey Cups, posted a 51-35 regular-season record and finished first in the East Division on three occasions.
