Yes, if they are within 64 km of the Sarnia city centre, our service radius for network cabling and installation companies. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.

No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.

By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does network cabling and installation, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.
Does network cabling need a licence?
It depends on where you are. Some states and provinces license low-voltage or limited-energy work (California’s C-7 low voltage classification and Washington’s limited energy specialty are examples) and many cities require permits. Ask the firm which licence and permits apply to your job.
What should we get when the cabling is finished?
Labelled cables and patch panels, test results for every run and a floor plan showing where each run goes. Those records make later changes and fault-finding much faster.
