  • Should we make OOS a model community for healthy aging?

    Should we make OOS a model community for healthy aging?

    Seniors Watch of Old Ottawa South believes that healthy aging, community involvement and economic regeneration are synergistic. We would like to demonstrate this by making Old Ottawa South a model age-friendly community as we rebuild from the pandemic. Our group of volunteers are working to identify needs as well as creative responses. We need to hear from everyone - seniors and others - who have an interest in making the neighbourhood an even better place in which to raise their families and grow old. Click here to fill out the survey!


We’ve come a long way since March of last year.  The Firehall is now offering summer camps and activities and preparing for Fall programs: in person and online. All of us at OSCA (staff and volunteers) thank you for your support and generosity. Your pledges and contributions have surpassed $85,000.

This summer the majority of our summer camps are outdoors at Windsor Park. Safety remains our top priority and we continue to meet and even exceed Ottawa Public Health COVID-19 recommendations. Our staff to child ratio is 1 to 5. We look forward to seeing you again this summer and fall.


442 Sunnyside to Become 17-Bedroom Student Rental

442 Sunnyside to Become 17-Bedroom Student Rental

According to the permit that is affixed to the fence in front of 442 Sunnyside, Konson Homes is building a three-level triplex with twelve bedrooms — four in each unit. However, it doesn’t take an expert to see that the five “dens and offices” noted on the plans will likely be used as additional bedrooms, bringing the practical total to seventeen. The largest apartment, which will take up the below-grade level and the ground floor has four bedrooms, two offices, one den, four bathrooms, one family room and one living/dining room.

Non-local Heavy Truck Traffic on Sunnyside Avenue

Non-local Heavy Truck Traffic on Sunnyside Avenue

Have you been bothered by the increase in heavy truck traffic on Sunnyside Avenue over the years? Non-local heavy trucks continue to use Sunnyside Avenue despite regulations that prohibit this. Heavy trucks can use non-designated truck routes for local deliveries and servicing, but this is meant only as an exception. Their use on this narrow residential street interfere with day-to-day life, work and sleep. It increases the risk to pedestrians, cyclists, and students, parents and employees of Hopewell Public School.

Bus 7 Stop at Sunnyside and Leonard to be Reinstated

Bus 7 Stop at Sunnyside and Leonard to be Reinstated

As mentioned in the April 2020 OSCAR, the longstanding number 7 westbound bus stop at the corner of Sunnyside and Leonard was removed in 2014 when the rain gardens were installed. Since then, some passengers descending from this bus had to walk about an extra 170 metres to get to their destinations.

An extra 170 metres doesn’t appear much if you are young, vigorous and the weather cooperates, but when you are getting on in years or have mobility problems, and the weather is so typically hot or cold, the footing slippery and uneven (as often happens in winter), the extra metres become a good reason to give up on busing.

Sunnyside Rain Gardens 2019

The City of Ottawa will be restoring the gardens within the next 4-6 weeks. They will inspect drainage, repair where necessary, add more soil (a unique composition to rain gardens) if required, and replant. We now know what survives!


From the Archives: Ottawa South Memories

In this excerpt from the March 1990 OSCAR, June Kelly O'Byrne recounts memories of life on Sunnyside Avenue from the 1920s and beyond, with recollections of family and friends, and recalls the many local stores and businesses in the neighbourhood.

Ottawa South Memories by June Kelly O'Byrne

In 1920 my parents bought a little house on Sunnyside Ave. on a big lot which extended to Woodbine Place. Dad had just returned from the First World War and was fortunate to obtain employment as a Letter Carrier. His "route", as he called it, encompassed Echo Drive at the Precious Blood Convent to Cameron Ave. (Cowan's Ice House and Wilson's Lumber Yard), east to the Rideau River, including what is now known as Rideau Gardens. Some senior citizens may remember him, as he received many a "tip" at Christmas time from the residents of those streets.

The two-story Marion House sits at the northwest corner of Sunnyside and Bristol. It was bordered from the north by a number of market gardens that were part of the original Williams farm before development took over the nearby area along Southern Drive and Avenue Road.


Sunnyside and Seneca Four Corners


Title: The Corner of Sunnyside Avenue and Seneca Street

Address: 431, 435, 437 Sunnyside Avenue and 41, 43, and 44 Seneca Street, Ottawa, Ontario.


The corner of Sunnyside Avenue and Seneca Street currently comprises four buildings which combine commercial and domestic spaces. In the early period of Old Ottawa South’s development (pre-1950) this corner had particular importance as one on which Ottawa’s streetcars turned. It has continuously included commercial spaces since 1907.


Sunnyside Tennis Club

The April 1979 OSCAR contained an article by Lindsay Suthren in which Mr. George Seal of Bellwood Avenue reminisced… “about his childhood in Ottawa South. He can remember the sounds of tennis playing on the four courts of the Sunnyside Tennis Club which was situated in the ravine behind St. Margaret Mary's Church, formerly Calvin Presbyterian Church. Tennis was very popular as was canoeing. There were a number of canoe clubs on the Rideau River and on the Canal within the Ottawa South area.”[1]

Tennis boomed in Ottawa in the 1920s. Many clubs – St. James, All Saints, St. Alban’s, and St. Joseph’s – were linked to churches and in 1924 Calvin Presbyterian Church at Sunnyside and Fairbairn acquired enough land behind the church to build six double tennis courts; in fact, only four courts were built.[2]

Sunnyside CutDownTreeIn 1971 an expected road widening changing the look and feel of a neigbhourhood street drastically.


The Ottawa Journal, Wednesday, June 16, 1971


The city was continuing work on transforming the shady one-way residential street in Ottawa South into a two-way artery which will connect Bank Street with the Bronson Avenue entrance of Carleton University.

The casualties in this, the latest skirmish in the battle of the automobile versus the environment, were 21 stately old trees.
