Glass guards · Mississauga
Glass guards and railings, balcony to basement stairs
The building code calls a railing that keeps people from falling a guard. In Mississauga, repairing or replacing a balcony guard needs a City permit. So the first questions are what kind of building it is and who is responsible for the guard. We connect you with an independent local professional who works on glass guards, explains the permit and approvals, and says when one panel can be replaced on its own.

A cracked panel
If a glass panel cracks: what to do first
A cracked guard panel is a safety problem. Take these steps in order.
Keep everyone off
Close the balcony door, keep children and pets inside, and don't lean on the rail.
Take photos
The crack, the whole guard and the fixings. They help the pro, the management office and any insurance claim.
Call the right person
In a condo or rental, the management office or landlord comes first. In a house, contact a pro.
Plan the repair
A temporary barrier can go up while the permit and the new panel are arranged.
Permits
Balcony guards need a City permit, even for repairs
The City of Mississauga's building permit page lists building a balcony, or replacing or repairing its guards, as permit work. That covers houses, apartments and condos, and like-for-like repairs as well as new railings.
The pro or a designer usually prepares the application details. Ask each pro who applies, and check the City's page for the current wording before you book.
Condo balconies
Condo balconies: the corporation decides first
On a condo balcony, the guard is typically not yours to change alone.
Check the declaration
It says whether the guard is part of your unit or a common element. In a tower, such as those in the City Centre, it is often a common element.
Report it to the management office
If the guard is a common element, the corporation arranges the repair and the permit.
Get approval before any change
An owner change to a common element needs board approval by resolution before work starts, usually recorded in an agreement registered on title. The condo window and balcony door guide walks through it.
Expect a matching look
Boards usually keep guards uniform across the building.
The glass
Glass in guards: laminated or tempered safety glass
The Ontario Building Code requires glass in guards to be safety glass, laminated or tempered. The type and thickness are set by the railing system and its design.
Tempered
Strong, and breaks into small, blunt pieces that leave the opening clear. A top rail often ties the panels together.
Laminated
Cracks but stays in the frame, which matters high above the ground. See glass cut to size for how the two differ.
Clear, tinted or frosted
A looks and privacy choice. In a condo, the corporation usually sets it.
Decks
Deck railings: posts, spigots and frameless options
On a house deck, the system has to suit the deck's framing.
Posts and panels
Glass set between aluminum or wood posts. The most common system, and the easiest to repair one panel at a time.
Spigots
Short steel clamps that hold each panel from below. They need solid blocking in the deck underneath.
Base shoe
A continuous channel that grips the bottom of the glass. It needs a strong, straight edge to fix to.

Indoors
Interior stair and landing railings
Glass works on stairs, landings and open lofts, including a basement stair being finished. The panels are safety glass, held by stand-offs on the side of the stair, a base shoe or posts. A handrail you can grip is usually still needed.
Heights and loads
Guard height and loads: who confirms them
The Ontario Building Code sets minimum guard heights and the loads a guard must resist, and they vary with the location and the drop. The railing's design sets the height and fixings, and the permit review confirms them. Managing several balconies? See the page for property managers.
