Backflow testing in Whitby
Whitby is on Regional water from the Lake Ontario plant in the town and sits under Durham Region By-law 24-2018 like every other municipality in the Region. There is no separate Whitby backflow program. Every ICI and multi-residential building on Regional water here has its device tested once a year and the report filed with the Region.
One program for all of Durham Region
The testing requirement in Whitby is set by Regional Municipality of Durham By-law 24-2018, the same by-law that covers every other Durham municipality. Notices come from BSI Online on the Region's behalf, reports are filed through the same portal, and the Region issues the tag. There is no separate Whitby program. See the Region's program page for the by-law and the tester registry.
Whitby’s building stock, from a backflow point of view
Whitby has more newer stock than Oshawa and a heavier industrial weighting than Ajax, which changes what turns up in mechanical rooms:
- Industrial and logistics. The 401 corridor and Port Whitby have the older employment lands; the north, around the 407 and 412 interchanges, has the newer prestige industrial parks the town has been developing. Distribution centres, manufacturers and their accessory offices are one property under the by-law, usually with several devices: premise RPZ or DCVA, boiler make-up RPZ, wash bay, sometimes irrigation. See the industrial page.
- Condominiums. Whitby has a lot of condo and townhouse-condo corporations built in the last twenty years. Clean mechanical rooms, well-labelled devices, and a property manager holding the notice. Buildings over six units are in the program. See apartments and condos.
- Retail plazas along Dundas, Thickson, Taunton and Brock: landlord premise device plus tenant devices in restaurants, salons and clinics.
- Downtown Whitby and downtown Brooklin. Restaurants, offices, small commercial. Restaurants carry RPZs and want after-hours slots.
- Institutional. Schools, places of worship, community facilities, and the Regional headquarters at Rossland and Garden. Institutional facilities departments often run their own compliance; the smaller ones call us.
The rule is Regional
By-law 24-2018 was passed by Durham Regional Council and administered through BSI Online. Whitby does not run its own program and its notices are not different from Oshawa’s or Ajax’s. If you have received a notice, the notice page explains what it asks. If you have not and think you should have, the annual requirement applies anyway; the notice is a reminder, not the trigger.
Water context
Whitby is served by Regional water from the Lake Ontario water supply plant in the town, one of the Region’s five lakeshore plants. Brooklin and the north are on the same Regional system. Properties in the rural north on private wells only are outside the program.
Scheduling in Whitby
Two clusters, both visited most weeks:
| Cluster | What is there | Usual slots |
|---|---|---|
| Lakeshore Whitby | Downtown, Port Whitby, the 401 corridor, Dundas and Taunton plazas, most condo stock | Restaurants before open or after close; condos mid-morning; industrial between shifts |
| Brooklin and the north employment area | Downtown Brooklin, the 407 and 412 industrial parks, newer subdivisions | Industrial sites grouped together; Brooklin restaurants after close |
A property manager with buildings in both clusters gets one schedule. A single Brooklin site with a tight due date gets folded into the next northern run or handled on its own; say which you need.
New buildings, first tests
Whitby’s newer stock means a lot of first-cycle tests. The device was installed and registered during construction and its first annual test falls a year later, often landing on a condo board or a new tenant that has never seen a notice before. New devices almost always pass; the visit is quick; the useful thing is to get the record right (correct owner contact, correct device details) so year two runs itself.
What it costs and what you get
Per device, per property, $25 BSI filing fee included, report submitted within the by-law’s 28-day window, tag on the device, report copy for the five-year file, filing confirmation, and a reminder 30 days before next year. Details on the cost page.
Scheduling in Whitby
Whitby splits into two clusters for us: the lakeshore town (downtown, Port Whitby, the 401 corridor, the Dundas and Taunton plazas) and Brooklin with the north employment lands. Both are on the schedule most weeks. Industrial sites in the north are grouped with each other; condo corporations are booked mid-morning with the super notified; downtown restaurants get before-open or after-close slots.
Backflow testing in Whitby: questions
Is Brooklin covered by the same rules as the rest of Whitby?
Yes. Brooklin is part of the Town of Whitby and on Regional water, so By-law 24-2018 applies exactly as it does downtown. We treat Brooklin and the north employment area as their own scheduling cluster because of the drive, not because the rule differs.
Our Whitby condo corporation just took over from the developer. Who handles backflow?
The corporation, through its property manager. The premise device on the common water service was installed during construction and registered with the Region; the first annual test is due a year after that. New buildings often have a clean, accessible mechanical room, which makes the visit quick. Send the notice or the address and we confirm what the Region has on file.
We are a distribution centre in the north employment area with several devices. One visit?
Yes. Premise device, boiler make-up, wash bay, irrigation: all on one visit, timed between shifts or during a planned outage for the premise device and line by line for the rest. Send the device list from the notice or let us build it from the Region's record.
