Ottawa, ON's backyards are full of sliding patio doors, and most of them are secured with nothing more than the factory latch they shipped with — a piece of hardware built to keep the door from sliding open on its own, not to resist someone actually trying to get in. Can-Lock Security installs and upgrades patio door security across Ottawa, and it's one of the most common gaps we find during a home security walkthrough.
The Vulnerability Most Ottawa Homeowners Don't Know About
Sliding doors can often be lifted slightly out of their bottom track, clearing the latch entirely, without needing a key, a tool, or any real skill — a technique that takes seconds and leaves no visible damage behind. This is especially true in Ottawa's older housing stock, where decades of use have loosened the track fit on doors that were already installed with more play than a newer door would have. Because patio doors sit at the back of the house, out of view from the street, an attempt here can also go unnoticed for longer than one at the front door.
Hardware We Install Across the City
- Security bars (charley bars), sitting in the interior track to physically block the door from sliding even if the latch is defeated
- Auxiliary pin locks, drilled through the frame and into the door itself, some adjustable to allow partial opening for ventilation while still blocking full entry
- Foot locks and floor bolts, mounted at the base of the door and difficult to disengage from outside
- Keyed patio door locks, useful for properties left unoccupied for stretches, including Ottawa condos used seasonally or homes with extended travel schedules
- Anti-lift track screws, closing the lift-and-shim vulnerability directly with no visible hardware added
Most Ottawa homes we visit benefit from pairing an anti-lift screw with either a security bar or an auxiliary pin lock — one closes the lifting vulnerability, the other reinforces the latch itself.
Older Homes vs. Newer Builds
In Ottawa's established neighbourhoods, older patio doors often have enough accumulated wear in the track that lifting the door takes very little effort, making anti-lift hardware a particularly high-value addition. In newer subdivisions across Barrhaven, Kanata, and Orleans, the tracks are usually tighter, but the factory latch itself is frequently just as weak as it is on an older door — meaning a security bar or auxiliary lock still closes a real gap even in a five-year-old home.
Screen Doors and Secondary Panels
Sliding screen doors get skipped entirely in most Ottawa security conversations, on the assumption that the glass panel behind them is the real barrier. In practice, a flimsy screen door latch offers almost no resistance, and reinforcing it is inexpensive relative to the peace of mind, particularly for ground-floor units and homes backing onto shared pathways or green space common throughout the city.
Matching Hardware to How You Actually Use the Door
A door your family uses constantly needs hardware that's quick to disengage without becoming a daily annoyance — usually a security bar. A rarely used patio door, or one on a seasonal property, can carry more restrictive hardware like a keyed lock or floor bolt, since convenience matters less when the door isn't opened every day.
Signs It's Worth an Upgrade
- The door has visible play or rattles when lifted in the closed position
- The factory latch feels loose or doesn't seat firmly
- The home sits vacant for stretches, including seasonal or travel-heavy households
- A nearby home has had a break-in through a back or patio door
- You're renovating or replacing the door and want security built in from the start
