Our Company
Whitby-based installers. GTA-wide coverage.
Keeping You Protected — professional security and low-voltage installation for homes and businesses, rooted at 1020 Dundas St E, Unit 1, Whitby, ON.
Ultimate Security designs, installs, and maintains the systems that keep properties visible and doors accountable: security cameras, access control, intrusion alarms, video doorbells, intercoms, and structured cabling. We work residential and commercial — from single-family homes to multi-door workplaces — with the same standard of clean cable work, labelled panels, and app setup that owners can actually use.
Being based in Whitby means Durham Region jobs get fast assessments and follow-up, while GTA projects in Scarborough, North York, Toronto, and Markham get scheduled service days with the same craftsmanship. We do not sell mystery “security kits.” We walk the site, map risk points, and write a proposal you can understand.
After install day, support continues: maintenance, expansions, repairs, and help recovering remote access when staff or networks change. Call 647-922-9884 or visit us at 1020 Dundas St E, Unit 1, Whitby, ON during business hours.
