Low Voltage Cabling Toronto
One subcontractor for the whole low-voltage scope. Structured cabling, fiber, CCTV, access control, paging and AV — installed by the same crew, through the same pathway, with one set of as-builts at closeout.
Velocity Cabling is a commercial low voltage contractor working across Toronto and the GTA. We install the full low-voltage scope — communications and electronic security — as a single subcontractor, working either from consultant drawings or from our own onsite survey. If you are a general contractor or facility director trying to avoid coordinating four separate vendors over one ceiling, this is the page for you.
What Actually Counts As Low Voltage
Low voltage means cabling that carries signal or limited power rather than building power. In practice that is anything under 50 volts, and in code terms Class 2 and Class 3 circuits under Section 16 of the Canadian Electrical Code, as adopted in Ontario by the Ontario Electrical Safety Code.
That covers a wider range than most people expect. Data and voice cabling, yes — but also camera and access control wiring, paging and intercom, AV and display cabling, and control wiring for building systems. It is a distinct trade from commercial electrical work, though the two frequently share a project and a ceiling.
Where it matters commercially: low voltage is usually specified and tendered separately from Division 26 electrical. If you are reading a spec that mentions Division 27 or Division 28, that scope is what we do.
Division 27 vs Division 28
Commercial specifications organise low voltage under CSI MasterFormat. Two divisions matter, and most buildings need both.
| Division | Title | Typical scope | We cover |
|---|---|---|---|
| 27 | Communications | Structured cabling, backbone and horizontal, voice, fiber, pathway, racks, distributed audio and paging, AV cabling | Yes, in full |
| 28 | Electronic Safety & Security | Access control, video surveillance, intrusion detection, intercom and door hardware interfaces | Yes, in full |
| 26 | Electrical | Building power, panels, circuits, lighting | Licensed electrical available — see electrical |
Why this matters on a tender. Splitting Division 27 and 28 across two subcontractors means two mobilisations, two sets of pathway, two schedules to coordinate and two parties to ask when a door reader will not talk to the network. Carrying both under one contract removes that interface entirely — and removes the argument about whose cable is at fault.
Systems We Install
Any combination of the below, on one contract and one schedule.
Fiber optic backbone
Riser and campus links, plus splicing and termination. See fiber cabling.
CCTV and surveillance
Camera pathway, PoE infrastructure and NVR rooms. See business CCTV.
Access control
Reader, REX, mag lock and controller wiring coordinated with door hardware. See access control.
Paging, intercom and AV
Zone paging, overhead PA, door intercom and display cabling. See paging systems.
Pathway and containment
Tray, basket, J-hook and conduit sized for the whole low-voltage scope rather than one system. See cable tray.
Plenum, Riser And Getting Past Inspection
Two things fail low-voltage inspections more than anything else: the wrong cable jacket rating, and inadequate separation from power.
Jacket ratings
CMP (plenum) is required wherever cable passes through a space used to handle environmental air — most commonly the void above a suspended ceiling used as a return air plenum. CMR (riser) is for vertical runs between floors. CMP costs more, and substituting CMR to save money in a plenum space is both a code violation and a genuine life-safety issue, because of what the jacket gives off in a fire. We have written this up in more detail if you want the full explanation.
Separation from power
Class 2 low-voltage circuits must be kept separate from Class 1 power wiring. That drives real decisions on site: dedicated tray or divided containment, spacing where runs are parallel, and proper crossing angles where they must intersect. Doing it properly also happens to reduce induced noise, so the code requirement and the performance requirement point the same way.
Working from a Division 27 or 28 spec?
Send us the drawings. We price from documents, attend site meetings, and submit shop drawings and closeout in the format the spec asks for.
Why One Low Voltage Contractor Beats Four
You can buy data cabling from one vendor, cameras from a security firm, access control from a door company and paging from an AV integrator. Plenty of projects do. Here is what it costs you.
Four vendors means four site set-ups, four sets of ceiling tiles lifted and four rounds of disruption to your floor.
Pathway sized once for the whole scope, rather than each vendor discovering the tray is already full.
No waiting for the cabling vendor to finish before the security vendor can start, with a week of float lost at each handoff.
A single documentation package your facility team can actually use, not four partial records in four formats.
When a reader will not communicate, nobody is blaming the other trade's cable. It is all ours to fix.
One estimator, one PM, one number. Particularly worth having on a phased or multi-site rollout.
From First Call To Certified Handover.
Five steps, same order, every job. You always know what happens next and who is on site.
Free Onsite Survey
We walk your space, document cable routes and flag every constraint. No cost, no obligation.
Written Proposal
Itemized quote covering materials, labour, timeline and compliance standard.
Pre-Install Planning
We coordinate with your PM, GC or IT team. Rack layouts and phasing locked before day one.
Expert Installation
Licensed technicians pull, dress, terminate and label every run to commercial spec.
Test & Certify
Every run Fluke tested. We don't leave until every port passes.

Low Voltage Questions.
What general contractors and facility directors ask us most about low-voltage scope.
Anything carrying signal or limited power rather than building power — generally under 50 volts, and in code terms Class 2 and Class 3 circuits under Section 16 of the Canadian Electrical Code as adopted by the Ontario Electrical Safety Code. In practice it means data, voice, CCTV, access control, paging, intercom, AV and control cabling: the systems in CSI Divisions 27 and 28.
Division 27 is Communications — structured cabling, data, voice, distributed audio, paging and AV. Division 28 is Electronic Safety and Security — access control, video surveillance, intrusion detection and intercom. Most commercial specs separate them, and most buildings need both. We hold both scopes, so you are not coordinating two subcontractors across one ceiling.
That is the point of hiring a low voltage contractor rather than individual system vendors. Same crew, same pathway, one set of as-builts and one number to call when something needs attention. It also removes the argument about whose cable caused the fault, because it is all ours.
Yes. We regularly work to Division 27 and 28 specifications issued by consultants and architects, price from drawings, attend site meetings, and submit shop drawings and closeout documentation in the format the spec asks for.
CMP plenum-rated cable is required where cable runs through a space used for environmental air handling, typically the void above a suspended ceiling used as a return air plenum. CMR riser-rated cable is for vertical runs between floors. Getting this wrong is one of the most common reasons a low voltage install fails inspection.
Every copper run is Fluke DSX tested to the relevant TIA-568 limits and fiber is certified to Tier 1 and Tier 2. You receive the full report along with labelling schedules to TIA-606 and as-built drawings before the project closes.
Yes, and it is included rather than an extra. Floor plans with outlet locations, patch panel schedules, TIA-606 label reports and the full certification results, delivered as one package. Your facility team gets a usable record instead of a job completion note.
