About us
Security is about more than standing guard. It's about showing up for people when it matters most. That's what we do at Sentry Security & Investigations (SSI).
Founded by Ian Townsend and Terry MacDonald, SSI brings together over 30 years in law enforcement and 30 years in private security. We've seen firsthand what real security means: not just deterrence, but protection, prevention and a proactive approach to safety.
Our trained, qualified officers offer an unparalleled level of service. We encourage a strong team atmosphere, where everyone is an integral part of a unit that delivers premium service to our clients.
We've grown into a team of 300+ trained security professionals across Nova Scotia and New Brunswick. But it's never been about numbers. It's about the people behind the uniform.
Our mission
Your people, assets and peace of mind. Integrity, discretion and professionalism are at the core of everything we do.
Whether it's a retailer preventing theft, a hospital needing patient watch, or a family seeking peace of mind through an investigation, we meet every challenge with integrity and accountability. We don't assign guards to a post and call it a day: we train, equip and empower our team to be the best in the field.
As a Nova Scotia company, we take pride in serving the communities where we live and work. We give back through emergency response support, community outreach, and mentorship and training for future security professionals. A strong community is a safe community.
Our team brings together backgrounds in law enforcement, security and risk management. We lead by example: our officers are trained not just to react, but to prevent, de-escalate and build safer environments.
Training & certifications
Our personnel complete rigorous training so they're ready for high-risk situations and emergency response.
Mental Health & Addictions / Trauma-Informed Care is a training course exclusively designed and delivered by Lydia McIsaac, RN, BScN, Senior Mental Health Education and Practice Consultant, Sentry Security.
At the end of the day, security is about people.
People who trust us to protect their businesses, communities and loved ones. People on our team, who show up every day ready to serve. And people like you, looking for a security partner you can rely on.
That's who we are. That's Sentry Security & Investigations.
Our team supports local initiatives, charities and community programs that make Nova Scotia safer for everyone, from security for public events to working closely with law enforcement.
