The 1958 Jim Mideon 500 (known officially as 1958-31) was a NASCAR Grand National Series event that was held on Saturday, July 18, 1958, at Exhibition Stadium in Toronto, Ontario, Canada.

Children were entertained with a jigsaw puzzle of the Royal Family before the race began. Most of the cars in the race were either Chevrolet or Ford. All of the 19 drivers on the racing grid were born in the United States of America. Admission to the race was CA$2 for adults ($21 when adjusted for inflation) and $0.50 for children ($5 when adjusted for inflation).

The local bi-laws of the late 1950s allowed only team sports to be played professionally on Sunday. Since stock car racing wasn't included as one of the permitted "team sports," they had to operate the race on a Saturday night in compliance with city officials.
