Vallengrove Park, now known as Centennial Park is a subdivision developed in 1961 between Wellesworth area and highway 27 by Vallen-Grove Developments. The three bedroom- one bath simple brick bungalows with garage on approximately forty-five foot wide lots sold for approximately seventeen thousand dollars new.

It was marked in the early 1960s by a red brick entrance at the then-connecting Birgitta Crescent to the long-gone off entrance from the southbound service road of then Highway 27 (a farm house stood here right at the ramp), and leading into the suburb between that west of 27 towards Wellsworth Park, and halfway north along Odessa Ave. and as far as Renforth. That new area was built in 1961; the older area further north along Odessa and out branching roads was built a few years earlier, wherever one sees the old wood hydro poles instead of concrete.

Vallengrove Park was once farmland; cows bones were found by children digging around before all areas were paved and settled, and another farm was at the location of Catholic church-Nativity of Our Lord and was torn down at same time. When the 27 was expanded into the 427, the east loop homes of Summerfield Crescent were expropriated around 1967, and moved to Bramalea. Part of their front lawns can be seen today at the sound barrier wall. Wellsworth school was opened in 1960 when hundreds of tulips were given by the Netherlands for planting. Tulips are still grown there almost 50 years later.

The area's high school was Vincent Massey Collegiate Institute. It closed in 1986 with a reunion there.

The northern most part of The West Mall is an important and very busy artery today but it originally ended as a bumpy, dirt bicycle path a short distance south of its intersection at Rathburn. The south end of that unfinished part continued to the edge of Burnhamthorpe, where Percy Bishop built the new Etobicore Mall across from the Shaver/Bishop farm house- then directly at the corner of Burnhamthorpe and The West Mall. Mr. Bishop gave land to Etobicoke in order for the road to be opened up, and had it built, around 1964.

This neighbourhood is home to people from a wide range of cultural backgrounds and levels of income. It has many fine attributes including an abundance of parkland, a diverse housing stock, a local library, an excellent selection of public and separate schools and convenient access to shopping and transportation. Its proximity to Centennial Park golf and skiing, and to the Etobicoke Olympium make it a wonderful family neighbourhood.
