New Home, New Neighbourhood: The Security Upgrades Toronto Buyers Are Making Before They Move In
June 1, 2026
Buying a Toronto home is a major investment. After the inspection and legal steps, the keys are finally yours.
Most new homeowners turn to paint colours and décor first.
But security should top your to-do list. Moving in is when your home is most at risk: you do not know who has the keys, you are unfamiliar with the neighbourhood, and your alarm system or locks may be outdated or unsecured.
Act now—complete your most important security upgrades within your first week. Follow this step-by-step plan before you even start unpacking.
Step 1: Rekey or Replace Every Lock on Day One
This is non-negotiable. You have no way of knowing how many copies of your keys exist: the previous owner, their family members, house cleaner, dog walker, contractor, and real estate agents who had access during the listing. Any of them may have a working key to your new home.
Rekeying is cheaper than replacing locks and just as effective. A locksmith resets the internal pins so previous keys no longer work. If you are upgrading to a smart lock system, do it now before you settle in and the project becomes more difficult.
Act now. Rekey every garage, back, and side door. Secure all keyed entry points before anything else.
Step 2: Assess Your Entry Points Like a Burglar Would
Walk around your new property and look at it the way someone casing it would. Ask yourself:
- Which windows are on the ground floor and visible from the street — and which are not?
- Do I have sliding glass doors? How secure are the frames and locking mechanisms?
- Are there shrubs or trees near windows or side doors that provide natural concealment?
- Which areas of my property have no exterior lighting?
- Does the neighbourhood have high foot traffic or low visibility from neighbouring homes?
This assessment tells you where your vulnerabilities lie before a criminal can identify them.
Step 3: Upgrade Your Door Frames Before Your Locks
Here is something most locksmiths will not tell you. The lock is rarely the weak point on a residential door. The frame is.
Builder-grade door frames use short screws, often 1 inch, that go into soft-wood casing rather than the structural stud behind it. A single hard kick will split that casing and pop the door open regardless of lock quality. This is one of the most common residential forced-entry methods in the GTA.
A steel door frame reinforcement kit with 3-inch screws anchored into the stud costs under $100 per door and takes about 30 minutes to install. It is one of the highest-ROI security investments you can make in a new home and almost no one does.
Reinforce every exterior door today. Upgrade deadbolts immediately after for the strongest protection.
Step 4: Deal With Your Windows Before Anything Else
If your new home has standard glass windows at ground level, and almost every Toronto home does, you have a vulnerability that your alarm system, cameras, and deadbolts do not address.
Standard residential glass breaks in a single strike. In three seconds, the burglar is inside while your alarm is just beginning to trigger.
This is the security gap that most new homeowners never close — and it is the gap that residential burglars exploit most frequently.
What Builders Don't Tell You About Your Windows
Builder-grade windows meet minimum code requirements for weather resistance and energy efficiency. They are not designed to resist forced entry. The glass and frames are standard. Unless you upgrade them, they will remain the easiest entry point in your home.
This is not a criticism of builders; it is simply not their mandate. Security glazing is a post-purchase upgrade and one of the most impactful you can make.
STRIKEGLASS: The First Security Upgrade Savvy Toronto Homeowners Are Installing
STRIKEGLASS from 416 Security Solutions reinforces your existing windows and glass doors against break-ins, enhancing security without replacement.
For new homeowners, STRIKEGLASS is particularly valuable because:
- Installation does not require window replacement or renovation and is typically completed in a day.
- STRIKEGLASS is transparent and does not alter your home’s appearance.
- It offers protection at all times, needing no activation, subscription, or power.
- Additional benefits include UV protection, noise reduction, and improved insulation.

Step 5: Set Up Exterior Lighting at Every Entry Point
Motion-activated lighting is cheap, fast to install, and highly effective against the casing behaviour that precedes most residential break-ins. Criminals rely on concealment, and lighting removes it.
Install exterior lighting at every entry today. Brighten front, back, and side doors, plus windows near shadows. Stop burglars before they act.
If your new home lacks exterior lighting fixtures, battery-powered motion lights are a quick interim solution while you arrange permanent installation.
Step 6: Install a Monitored Alarm System
A professionally monitored alarm — where a 24/7 monitoring centre dispatches emergency services when triggered — is the detection backbone of any residential security system.
Set up a new monitored alarm on move-in day. Activate your system and monitor all sensors yourself—don’t delay.
Key features to look for:
- Cellular backup — so cutting your internet does not disable your alarm
- Battery backup — so a power outage does not disable your alarm.
- Glass break sensors — trigger on the sound of breaking glass rather than waiting for a contact sensor to open
- Door and window contact sensors on all ground-floor entry points
Options to consider in the Toronto market include ADT, Alarm Force, Telus SmartHome Security, and SimpliSafe. Compare monthly monitoring costs and contract terms carefully.
Step 7: Add Visible Cameras and a Video Doorbell
Cameras serve a different purpose than alarms or physical barriers. They change the risk calculus for opportunistic criminals during target selection. A home with visible cameras is passed over more frequently than one without because the perceived risk of identification increases.
A video doorbell at the front door, combined with one or two exterior cameras covering the back yard and side entries, covers most of a typical Toronto property. Look for 1080p minimum, night vision, motion alerts, and local storage backup.
Position cameras and a video doorbell clearly and immediately. Increase deterrence from the moment you arrive.
Step 8: Get to Know Your Neighbours
This one costs nothing and pays significant dividends. Neighbours who know you are new, your car, and your patterns will notice when something is off. A neighbour who sees an unfamiliar person trying your back window at 10am and calls you or 911 is worth more than most security systems.
Introduce yourself in your first week. Meet your immediate neighbours and join your local Nextdoor group for timely security alerts. Take action to build connections now.

Frequently Asked Questions
How soon after moving in should I change my locks?
Day one. This is not optional. You have no way of knowing how many key copies exist from previous occupants and their contacts. Rekeying is fast, inexpensive, and removes the immediate risk of unknowns.
Do I need a security system if the previous owners had one?
Yes. Even if existing hardware is present, assume it is not active, connected, or monitored. Set up a new account with your preferred monitoring provider and verify all sensors work before relying on the system.
How does STRIKEGLASS installation work in a new home?
STRIKEGLASS is a retrofit system that mounts over your existing windows without requiring replacement or significant construction. A 416 Security Solutions technician will assess your windows, confirm compatibility, and complete installation. Most homes are done within a single day with no disruption to your move-in process.
What is the most important security upgrade for a new Toronto home?
Physical protection at your glass entry points, windows and sliding glass doors, is the most commonly overlooked and frequently exploited vulnerability in residential security. STRIKEGLASS addresses this gap directly and is the upgrade most security professionals would prioritize first for a new home, followed by door frame reinforcement and a monitored alarm system.
Will these upgrades affect my home insurance premiums?
Potentially yes. Many Ontario home insurers offer premium reductions for monitored alarm systems and may recognize certified physical security measures. Contact your insurer after completing upgrades and ask specifically which improvements qualify under your policy.
The Bottom Line
Moving into a new home is one of the best opportunities you will ever have to build your security infrastructure from the ground up — before any vulnerabilities have been tested, and before any incidents have occurred.
Most of the upgrades on this list are fast, affordable, and permanent. The rekeying happens in the afternoon. The door frame reinforcement takes an hour. The STRIKEGLASS installation is completed before the movers finish.
The investment is modest. The peace of mind — and the actual physical protection — lasts for as long as you own the home.
