Dwyer scored in the 74th minute and the 86th for Sporting (3-1-2), which is unbeaten in its last five matches and tied with Columbus atop the East.
Aurelien Collin also scored for Kansas City with a left-footed shot just inside Troy Perkins' left post in the 71st.
Montreal (0-4-3) fell behind 1-0 in the 31st minute when midfielder Calum Mallace headed a throw-in into his own net.
Eric Kronberg needed to make just two saves to record his third shutout of the year for Kansas City.
