During his 17-year Major League Baseball (MLB) career, he played with the Montreal Expos, Colorado Rockies, and St. Louis Cardinals.

The first player in more than 60 years to record a batting average of .360 in three consecutive seasons from 1997 to 1999, Walker also won three NL batting championships. He was inducted into Canada's Sports Hall of Fame in 2007, and the Canadian Baseball Hall of Fame in the Class of 2009, and was named the 13th-greatest sporting figure from Canada by Sports Illustrated in 1999. In 2020, he was elected to the Baseball Hall of Fame.
