The Region was incorporated in 1974 to efficiently provide community services to the massive area. Owing to immigration and its transportation infrastructure (six highways pass through Peel and the Pearson International Airport is within its boundaries), the Region of Peel is a rapidly-growing area with a young population and an increasing profile. In recent years, the torrid growth in Mississauga has prompted many in the city to call for it to withdraw from Peel and become a single-tier city, arguing it pays far more into the Region and relinquishes far too much power.
A fair guess can be made that the Region of Peel was named after Robert Peel, the nineteenth-century Prime Minister of Great Britain.
