The 58th Grey Cup was played on November 28, 1970 before 32,669 fans at Exhibition Stadium at Toronto. The Montreal Alouettes defeated the Calgary Stampeders 23 to 10. The Grey Cup game was dominated by the woeful condition of the field with the turf coming away in chunks.

Both teams had finished third in league play. Montreal was third place in the East Division at 7-6-1, and Calgary was third in the West with a 9-7-0 record.

The Alouettes were coached by former Als great Sam Etcheverry.

Als quarterback Sonny Wade demonstrated the condition of the turf when he hurled a huge chunk of grass out of his way to take a snap. The field condition was described as "disgraceful". It was the last Grey Cup final game to be played on a natural grass surface until 1984 at Edmonton's Commonwealth Stadium.

Sonny Wade won the first of his 3 Grey Cup Most Valuable Player awards
