Protecting the National Capital Region since 1992.

For decades, Alliance Security has been the preferred choice for discerning Ottawa-area home owners who want the best in home security, installed by certified, experienced professionals.

Our approach is simple: Offer top-of-the-line products for the right price, then back them up with efficient, invisible installations, 24-hour ULC monitoring and smarter technology options to provide each client with protection and ‘no false alarm’ peace of mind.

As a locally-owned, family-run company first founded in 1970 before being taken over by owner and certified electrician, Terrill Leclair, we put the security and wellbeing of our thousands of clients first. We ensure that when a customer buys home monitoring, they’re not only getting peace of mind, but personalized customer care, as well.

Unlike cheaper “no frills and no money down” systems that trigger disruptive and costly false alarms, we guarantee our products will do the job right, all the time. In fact, all of our custom systems come with a written ‘no false alarm’ guarantee.

And if you do experience problems, we’re big enough to respond quickly and small enough to do so personally.

Alliance Security…protecting your world.
