Oshawa neighbourhood guide

O'Neill

O'Neill is Oshawa's old north end, the grid of tree-lined streets between Simcoe Street North and Ritson Road North where the city's early industrial money built its houses. It takes its name from O'Neill Collegiate and Vocational Institute, the school at 301 Simcoe Street North that opened as Oshawa Collegiate Institute in the early 1900s and was later renamed for its long-serving principal. R.S. McLaughlin's Parkwood Estate, a National Historic Site, stands across Simcoe at the community's south-west corner, with Lakeridge Health Oshawa and its regional cancer centre beside it. Housing is a century deep: Edwardian and 1920s brick houses on Simcoe, Masson and Alexandra streets, 1940s and 1950s storey-and-a-halfs and bungalows east toward Ritson, 1960s and 1970s apartment towers along Simcoe and Mary streets, and a scatter of infill. Residents range from hospital and university staff who walk to work, to long-time owners, to renters in the towers. Alexandra Park and the golf club's fairways give the area more open green than any other central neighbourhood, and downtown's arena, restaurants and the Ontario Tech downtown buildings are a short walk south.

Where O'Neill sits

O'Neill is the older neighbourhood directly north of downtown Oshawa, east of Simcoe Street North. Most guides run it from about Adelaide Avenue East north to Rossland Road East, with Ritson Road North on the east, taking in Mary Street North, Central Park Boulevard North and the streets around Alexandra Park and the Oshawa Golf and Curling Club. Whether the blocks between Bond Street and Adelaide, including O'Neill Collegiate itself, belong to O'Neill or to Central varies by map, so treat the southern line as roughly drawn.

The homes you will find

The oldest houses stand along Simcoe Street North and on Masson, Alexandra, Hillcroft and Elgin streets: two and two-and-a-half storey brick from the 1900s to the 1930s, some grand, many converted at some point to duplexes or offices and a good number restored since. East of Mary Street North the stock is smaller and later, storey-and-a-half wartime and immediate post-war houses on 40 to 50 foot lots, brick bungalows from the 1950s, and semis and a few small walk-up apartments toward Ritson Road North. Central Park Boulevard North and the streets near the golf club hold larger mid-century houses on generous lots. Along Simcoe and Mary streets and near Rossland Road East, rental and condominium apartment towers from the 1960s and 1970s rise above the houses. Infill is steady rather than dramatic: replacement two-storeys on old lots, a few small townhouse rows and the occasional new low-rise condo. Detached garages, driveways down the side and 100-foot-deep lots are typical of the older blocks.

Getting around

Simcoe Street North carries the 901 PULSE, Durham Region Transit's busiest line, south to the downtown terminal and north to the university campus, and the Highway 2 PULSE buses from Pickering and Scarborough reportedly end downtown a few blocks away. Local routes run on Mary Street North, Ritson Road North and Adelaide Avenue East, and the 916 crosses the top of the community on Rossland Road East. Oshawa GO is about a ten-minute drive or one bus transfer away, and the Central Oshawa GO stop planned for 500 Howard Street, part of the extension toward Bowmanville, will be closer still once built. Highway 401 is reached via Simcoe Street or Ritson Road South. The community is one of the few in Oshawa where walking is realistic: downtown, the hospital, the arena and the Ontario Tech downtown buildings are all within about a kilometre and a half of most streets, and cyclists use the Oshawa Creek path just west of Simcoe.

Schools

O'Neill Collegiate and Vocational Institute, the Durham District School Board high school that gives the community its name, offers the regular academic streams and reportedly hosts the board's regional arts program. The public elementaries most often reported for the area are Dr. S.J. Phillips and Mary Street Community School, with French immersion available through the board at designated sites. On the Catholic side, St. Gregory Catholic School near St. Gregory the Great parish on Simcoe Street North is the usual elementary, feeding Monsignor Paul Dwyer on Stevenson Road North or Monsignor John Pereyma in the south end. French-language boards run École élémentaire Antonine-Maillet (Viamonde) and École élémentaire catholique Corpus-Christi (MonAvenir) in Oshawa. School assignments follow board-drawn boundaries that shift over time, so verify the schools tied to a specific address. Ontario Tech's downtown campus is walkable and Trent University Durham sits near Oshawa GO.

Parks, shopping and daily life

Alexandra Park, among the city's oldest, sits at the community's centre with its lawn bowling greens, ball diamonds, playground and the Kinsmen Civic Memorial Stadium, and the private Oshawa Golf and Curling Club spreads across the blocks north of Alexandra Street. Parkwood's gardens are open to visitors in season, and the Oshawa Valley Botanical Gardens and the creek trail are a short walk west across Simcoe. Daily shopping happens at Simcoe Street North's plazas, at the stores along Ritson Road North and Adelaide Avenue East, and downtown, where the Tribute Communities Centre, the Regent Theatre, the Robert McLaughlin Gallery and a growing set of restaurants and cafés sit within a fifteen-minute walk. The Oshawa Centre mall is about a five-minute drive west on King Street. Lakeridge Health Oshawa, the largest hospital in Durham Region, is at the south-west corner, which means both convenience and ambulance sirens. The McLaughlin branch of the public library is downtown on Bagot Street.

Who it suits

O'Neill suits buyers who want character, a walkable location and a big lot with mature trees, and who accept that a century house needs ongoing care. It is a natural fit for hospital and university staff, for downsizers who want a bungalow near services without leaving the city core, and for investors interested in legal duplexes and the apartment market near the campus bus. It suits fewer people who want a turnkey new house with an attached double garage, a quiet cul-de-sac or a uniform streetscape, and the blocks nearest downtown and the towers see more foot traffic, noise and parking pressure than the rest of the community.

Questions people ask about O'Neill

Is O'Neill a good place for commuting to Toronto?

It is one of the easier Oshawa neighbourhoods for it. Oshawa GO is a ten-minute drive or one bus transfer down Simcoe Street, Highway 401 is reached at Simcoe or Ritson, and the future Central Oshawa GO station on Howard Street will be even closer. Toronto-bound drivers can also reach Highway 407 north on Simcoe in about ten minutes.

What schools serve O'Neill?

O'Neill Collegiate on Simcoe Street North is the public high school, with Dr. S.J. Phillips and Mary Street Community School reported as the elementary feeders. Catholic students typically attend St. Gregory and then Monsignor Paul Dwyer or Monsignor John Pereyma. Both boards draw their own boundaries and revise them, so check the assigned schools for the exact address.

Are the old houses in O'Neill expensive to maintain?

They can be. Expect knob-and-tube or early wiring in unrenovated houses, original plaster, single-pane windows, older roofs and cast-iron or clay drains, and mature trees that need pruning. Many have been fully updated, and the insurance and inspection reports will tell you which. Budget for the unknowns and hire an inspector who works on pre-war houses.

Is there much rental housing in O'Neill?

Yes. The 1960s and 1970s towers along Simcoe and Mary streets are largely rental, a number of the large old houses are legal duplexes or triplexes, and students and hospital staff rent basement suites. That mix keeps the streets lively and supports investors, but owner-occupiers should check what a particular block looks like on a weekday evening.

How walkable is O'Neill?

Very, by Oshawa standards. Downtown, the arena, the hospital, Alexandra Park, grocery stores on Simcoe Street and the downtown bus terminal are all within a twenty-minute walk from most streets, and the 901 bus runs often. The grid layout and sidewalks on both sides help. Parking is tighter near the hospital and the towers.
