Some buildings cannot tolerate a missed sequence, a late equipment delivery, or an unverified penetration. Data centers, solar farms, industrial facilities, high-security buildings, and complex operational sites demand more than general construction — they demand a contractor that can coordinate utility coordination, long-lead equipment, hardened envelopes, redundant mechanical/electrical systems, and strict commissioning protocols without ever losing the schedule.
With more than 20 years of hands-on construction, restoration, and project-management experience across Eastern Ontario and now the Greater Toronto Area (GTA), our complex-projects division has the planning depth, supplier network, and on-site discipline to deliver projects where standard general contractors stall. We work in Kingston, Toronto, Mississauga, Brampton, Vaughan, Markham, Oakville, Burlington, Oshawa and across the broader Ontario corridor — and we coordinate equally well with hyperscale operators, IPPs, industrial owners, institutional clients, and federal/provincial security tenants.
If your project requires a contractor who can read a single-line diagram, sequence a 4-week generator delivery against a building-envelope close-in, and pass a SCIF or CSA Z32 commissioning checklist — you're in the right place.
Our IICRC-aligned protocol
- 1
Pre-construction & feasibility
Site due diligence, utility capacity studies, geotechnical and environmental review, permitting strategy with the AHJ, and Class 3 → Class 1 cost estimates. We lock the constructability story before mobilization.
- 2
Integrated planning & logistics
Critical-path schedules with long-lead equipment (transformers, switchgear, CRAH units, PV inverters, racking, security hardware) sequenced against site enabling works. Lay-down areas, crane picks, road bonds, and night-delivery permits coordinated in advance.
- 3
Site enabling & civil works
Heavy civils, deep utilities, foundations, equipment pads, perimeter security, access roads, and stormwater — built to support the mechanical, electrical, and security systems that will be installed on top.
- 4
Mechanical, electrical & specialty trades
MEP coordination with BIM clash detection, redundant power distribution (N+1, 2N), precision cooling, fire suppression (FM-200, Novec, pre-action), grounding/bonding, EMI/RFI shielding, and SCADA/BMS integration.
- 5
Commissioning, security & turnover
Level 1–5 commissioning, IST (integrated systems testing), security accreditation support (CSA, RCMP T-SCIF, ITSG-22 considerations), as-built drawings, O&M manuals, and warranty handover with a single point of accountability.

Now serving the Greater Toronto Area (GTA)
We are expanding our Ontario footprint with a new Greater Toronto Area office, giving our complex-projects division direct presence in the largest construction market in Canada. From the GTA we serve Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Pickering, Ajax, Whitby, and Oshawa, with field crews mobilizable across Southern and Eastern Ontario from either office.
The GTA office focuses on data center build-outs, industrial and logistics facilities, solar and BESS projects, and high-security tenant fit-outs. Our Kingston head office continues to anchor Eastern Ontario coverage and overflow capacity, so our clients see one Ontario-wide contractor with two coordinated dispatch points and a single project-management standard.
Data center construction across Ontario
Whether you're delivering a 2 MW colocation suite in Markham, a hyperscale shell expansion in Mississauga, or an edge node in Eastern Ontario, the discipline is the same — concurrent maintainability, verifiable redundancy, and a commissioning trail that satisfies the operator and the insurer. Our teams have delivered base-build, white-space fit-out, generator yard expansions, and chilled-water plant upgrades, all sequenced against live tenant load.
We work to Uptime Institute Tier objectives, ASHRAE TC 9.9 thermal guidelines, and TIA-942 infrastructure standards, with grounding and bonding to IEEE 1100 (Emerald Book). Critical environments mean zero-tolerance for water intrusion — and that is exactly the failure mode our restoration history has trained us to design out.
Solar farms & battery storage (BESS)
From utility-scale ground-mount arrays in rural Ontario to commercial and industrial (C&I) rooftop systems in the GTA, our crews handle access roads, pile driving, racking erection, DC string installation, inverter and transformer setting, MV interconnection civils, and SCADA commissioning. We coordinate directly with the IESO, local LDCs (Hydro One, Toronto Hydro, Alectra, Hydro Ottawa), and EPC partners to keep energization dates on track.
Battery energy storage (BESS) projects are delivered with fire-code compliance to NFPA 855 and CSA C22.2 No. 340, including thermal runaway containment, deflagration venting, and emergency-services pre-planning.
Industrial buildings & advanced manufacturing
Manufacturing plants, distribution centers, cold storage, food-grade facilities, and process buildings require a contractor that understands floor flatness for VNA racking, food-grade insulated panels, vapour barriers under freezer slabs, process-piping coordination, and explosion-proof electrical zones. We deliver tilt-up, structural steel, precast, and hybrid systems with clear-span requirements up to and beyond 40 metres.
Across the GTA's logistics corridors (Highway 407, 401, 400, and the Niagara-GTA trade route) we deliver fast-track industrial shells and tenant fit-outs without compromising commissioning quality.
High-security & complex operational buildings
High-security buildings — federal facilities, courthouses, secure data handling sites, financial vaults, telecom switch sites, utility control rooms, and SCIF-ready spaces — demand specialized envelope construction, EMI/RFI shielding, blast and ballistic-rated assemblies, mantrap and access-control integration, and uncompromised chain-of-custody on every trade entering the site. Our crews are background-screen ready and our project paperwork is built to satisfy security-accreditation reviews.
Complex operational buildings — hospitals, laboratories, broadcast facilities, transit operations centers, water-treatment plants — share the same intolerance for downtime. We sequence shutdowns, build temporary services, and execute phased turnovers so operations never stop.
Why owners and developers pick us for complex builds
Two decades in restoration taught us what happens when a construction detail fails — water in a switchgear room, a missed firestop in a riser, a vapour barrier short-circuited at a slab edge. That field perspective is built into every drawing review, every submittal, and every site walk we perform. Our planners think in failure modes, not just bills of material.
Add disciplined logistics, mature long-lead procurement, an Ontario-wide subcontractor bench, and a single project-management standard across both our Kingston and GTA offices, and you get a contractor who finishes complex projects on the schedule that was promised.

Frequently asked questions
What is a 'complex construction project' for 24/7 Remedial Services?
Complex projects are builds where logistics, long-lead equipment, redundancy, security, or commissioning rigour exceeds what a general commercial GC typically handles. Examples include data centers, solar farms and BESS, industrial manufacturing plants, cold storage, high-security and SCIF-ready buildings, hospitals, laboratories, and 24/7 mission-critical operational facilities.
Where in Ontario do you deliver complex projects?
Across all of Ontario, anchored by two offices: our Kingston head office (serving Eastern Ontario — Kingston, Belleville, Brockville, Ottawa Valley, and surrounding regions) and our new Greater Toronto Area (GTA) office (serving Toronto, Mississauga, Brampton, Vaughan, Markham, Oakville, Burlington, Oshawa, and the wider GTA / Golden Horseshoe).
Do you build data centers in the GTA?
Yes. From the GTA office we deliver data center base-build, white-space fit-out, generator yard expansions, chilled-water plant upgrades, and edge / colocation facilities across Toronto, Mississauga, Markham, Vaughan, and the surrounding region. Our work aligns with Uptime Institute Tier objectives, ASHRAE TC 9.9, TIA-942, and IEEE 1100 grounding standards.
Do you build solar farms and battery energy storage (BESS) sites?
Yes. We deliver utility-scale ground-mount solar, C&I rooftop systems, and BESS sites across Ontario — including civils, pile driving, racking, DC strings, inverter and transformer setting, MV interconnection, and SCADA commissioning. BESS projects are delivered to NFPA 855 and CSA C22.2 No. 340.
Can you handle high-security and SCIF-ready buildings?
Yes. We build envelopes and interiors for high-security buildings — including EMI/RFI shielding, blast and ballistic-rated assemblies, mantrap and access-control integration, hardened doors and windows, and chain-of-custody site protocols. Our project paperwork is built to support security-accreditation reviews.
What delivery models do you offer?
Stipulated lump sum, design-build, construction management (CM at risk and CM as agent), EPC, and owner's representative engagements. We tailor the model to the project's risk profile and the owner's preferred procurement approach.
How does your restoration background help on complex construction?
Two decades of restoration work means we know exactly how buildings fail — water in switchgear rooms, missed firestops, vapour-barrier short circuits, soot infiltration in MEP systems. We design and inspect with those failure modes in mind, which reduces commissioning rework and long-term operational risk.
Do you do work for government, institutional, and Crown clients?
Yes. We deliver federal, provincial, and municipal projects, as well as institutional builds (hospitals, post-secondary, transit operations centers, utility control rooms). We are accustomed to public-sector procurement, prevailing-wage compliance, and the documentation standards Crown agencies require.
How do I request a proposal for a complex project?
Email dispatch@247remedialservices.ca with the project name, location, scope summary, and target schedule — or call (855) 324-7356 and ask for the complex-projects desk. Qualified RFPs and RFQs receive a same- or next-business-day response from either our Kingston or GTA office.
