Accessible parking is not optional for commercial properties in Ontario. Furthermore, under the **Accessibility for Ontarians with Disabilities Act, 2005 (AODA)**¹ and **Ontario Regulation 191/11 – Integrated Accessibility Standards (IASR)**², property owners and managers must meet specific technical requirements.
2026 Compliance Alert
If your organization has 20 or more employees, your next mandatory Accessibility Compliance Report is due by December 31, 2026⁵. Consequently, ensuring your parking lot meets Part IV.1 standards is a primary component of this legal filing. Failing to file or providing inaccurate data can trigger audits and daily fines of up to $100,000 for corporations¹.
Beyond the Blue Paint: Protecting Your Property from AODA Non-Compliance Penalties
The Ontario government enacted the AODA to make the province fully accessible. Therefore, under the Design of Public Spaces Standards, organizations must ensure that newly constructed or redeveloped public-use parking areas meet accessibility requirements².
Important Trigger: While routine maintenance (like filling a single pothole) may not trigger an overhaul, re-striping or resurfacing an entire lot constitutes a “significant alteration.” As a result, this work requires you to bring the layout up to current AODA standards².
Types of Accessible Parking Spaces Required
Ontario requires two distinct types of accessible parking spaces to accommodate different mobility needs².
1. Type A Accessible Spaces (Van Accessible)
Crews design these spots specifically for vehicles equipped with ramps or lifts.
-
Minimum Width: 3,400 mm².
-
Signage: You must install the International Symbol of Access (ISA) PLUS a “Van Accessible” tab³.
-
Location: Place these on the shortest accessible route to the building entrance².
2. Type B Accessible Spaces (Standard Accessible)
These serve users who do not require a ramp but need proximity to the entrance.
-
Minimum Width: 2,400 mm².
-
Signage: This spot requires the standard ISA vertical sign³.
Access Aisle and Surface Requirements
Each accessible space must have an adjacent access aisle to allow for safe transfers². In addition to width requirements, you must consider the following:
-
Width: Minimum 1,500 mm².
-
Marking: Clearly mark these with high-contrast diagonal lines to discourage non-accessible parking².
-
Slope: The surface must remain virtually flat. Specifically, the law allows a maximum slope of 1:50 (2%) in any direction². Surfaces must stay firm, stable, and slip-resistant.
How Many Spaces Do You Need? (The 2026 Scale)
The total lot capacity determines the number of required spaces². However, note that when you require an even number of spaces, you must split them 50/50 between Type A and Type B.
| Total Parking Spots | Minimum Accessible Spaces | Breakdown (Type A / Type B) |
| 1–12 | 1 | 1 Type A |
| 13–25 | 1 | 1 Type A |
| 26–50 | 2 | 1 Type A, 1 Type B |
| 51–75 | 3 | 1 Type A, 2 Type B |
| 76–100 | 4 | 2 Type A, 2 Type B |
| 101–200 | 1 + 3% of total | Split equally |
Signage and Pavement Markings
Faded paint or improper sign height represent “low-hanging fruit” for liability claims. To avoid this, follow these standards:
-
Vertical Signage: Mount signs at the head of the space. Moreover, the center of the sign should sit between 1,500 mm and 2,000 mm from the ground for maximum visibility³.
-
Pavement Markings: Paint the International Symbol of Access (ISA) directly on the pavement. These markings should measure at least 1525 mm x 1525 mm and utilize high-durability, slip-resistant paint².
Maintenance & Snow Removal Liability
Under the **Occupiers’ Liability Act (Ontario)**⁴, property managers must ensure the premises remain reasonably safe.
-
The Snow Rule: An accessible space becomes legally non-compliant if you use it for snow storage. Similarly, you must keep access aisles as clear as the spots themselves².
-
Audit Tip: Perform a “Spring Walkthrough” annually. By doing so, you can check for UV-faded lines and frost-heave that may have altered the 1:50 slope.
