Demolition Services You Can Trust

A demolition contractor is a specialized firm or individual responsible for the planned, controlled, and safe dismantling or removal of structures, all while strictly following the Ontario Building Code (OBC) and provincial safety laws.

Here’s a breakdown of what we handle demos from start to finish:

1. Mandatory Pre-Planning: We start by inspecting the site and developing a detailed safety strategy. This step is critical for legal compliance.
2. Hazardous Material Check: This is vital. We conduct or commission a Designated Substance Survey (DSS) to detect and safely manage materials like asbestos and lead, in line with provincial regulations.
3. Utility Disconnection: Before any major work begins, we coordinate with providers (Hydro One, Enbridge Gas, local water services) to ensure all services are safely disconnected and capped – a non-negotiable step for site safety.
4. The Demolition: Using specialized equipment, we execute the tear-down, whether it’s a full structure removal or selective interior work, with precision, minimizing impact on surrounding properties.
5. Debris and Cleanup: Once the structure is down, we don’t just leave a mess. We meticulously sort materials for recycling and haul all debris to approved transfer stations, ensuring environmentally responsible disposal.
6. Site Preparation: We leave the site clean, level, and ready for the next phase of development.

Choosing the right contractor is the most important decision you’ll make. It ensures your project is legal, safe, and doesn’t expose you to liability. Follow these key steps:

1. Verify Credentials: This is absolutely essential. You must get proof of a valid Workplace Safety and Insurance Board (WSIB) account and current Commercial General Liability (CGL) insurance. If they don’t have these, walk away immediately.
2. Review Local Requirements: Check if your municipality (especially in larger urban centres, like Toronto) requires the contractor to hold a specific local license or registration to operate legally.
3. Get Detailed, Itemized Quotes: Ask at least three reputable companies for a comprehensive, written proposal. The price should clearly break down costs for labour, permits, utility work, and the handling of any hazardous materials (like asbestos abatement).
4. Check Their Safety Track Record: Ask about their internal safety program and compliance with the Occupational Health and Safety Act (OHSA). A responsible contractor will always prioritize site safety and worker training.
5. Research Past Clients: Request references from recent projects similar to yours. A quick call to a previous client provides genuine insight into their reliability and professionalism.
6. Finalize the Contract: Make sure the signed agreement clearly outlines who is responsible for securing the demolition permit and conducting the mandatory pre-work surveys.

“Can you show me your current WSIB Clearance Certificate and proof of General Liability coverage?”

Why does it matter: This is your primary defence against lawsuits. It confirms they’re a legal, insurable business and protects you if a worker is injured or property is damaged.

“Who is responsible for the Designated Substance Survey (DSS), and do you have a plan for asbestos removal?”

Why does it matter: The DSS is a provincial requirement before demolition. You need to know if they handle the abatement themselves or use a specialized, certified subcontractor.

“How will you notify the Ministry of Labour (MOL), and what’s your on-site safety plan?”

Why does it matter: For larger projects, they need to file a Notice of Project (NOP) with the MOL. This question confirms they understand and follow the strict OHSA protocols.

“Can you detail your procedure for disconnecting and capping all utilities (gas, hydro, water)?”

Why does it matter: Utilities must be officially disconnected at the property line by the proper provider, not just cut. This prevents severe accidents and massive liabilities.

“What measures will you take to control dust, noise, and vibration?”

Why does it matter: This shows their awareness of local municipal bylaws and their consideration for neighbours, minimizing the risk of project-stalling complaints.

The demolition permit is issued by your local municipal Building Department under the authority of the Ontario Building Code Act. We recommend applying for your demolition permit along with other required permits, this will streamline the overall process. 

Below we have outlined the process to apply:

1. Get the Designated Substance Survey (DSS): Before submitting any permit application, a qualified consultant must complete a DSS. This report, which confirms or denies the presence of hazardous materials, is a mandatory attachment to the permit application.
2. File the Application: The contractor submits the formal Application for a Permit to Construct or Demolish to the local municipality.
3. Gather Support Documents: This submission package is extensive, including the DSS report, a site plan, proof of all utility disconnections, and evidence of the contractor’s WSIB and insurance standing.
4. Fee Payment: You will pay the permit fee, which is based on the size and complexity of the structure.
5. Review and Approval: The Chief Building Official reviews the submission to verify that it complies with the Building Code, local zoning, and the Ontario Heritage Act.
6. Start Work: Once the permit is issued – a process that has mandated review times – it must be posted visibly on the site before the first piece of machinery touches the structure.

ALMAR Demolition does not include permit applications as part of our service, however, if required we can assist for an additional fee.

Operating a demolition company legally requires meeting specific criteria set by both provincial authorities and local municipalities.

Licensing and Registration:

• Provincial Trade Qualifications: While demolition itself isn’t a compulsory trade, all specialized workers on the site (like electricians, plumbers, or specific heavy equipment operators) must hold a valid provincial Certificate of Qualification (C of Q).
• Municipal Licensing: In major cities, you may find that contractors need a specific municipal business license or registration to bid on and operate projects within that city’s limits. Always check with the local city hall.
• WSIB Registration: The contractor must be registered and in good standing with the Workplace Safety and Insurance Board (WSIB). This isn’t optional for an ethical company.

Required Insurance Policies

A responsible contractor will carry robust insurance policies designed for the high risks of demolition:

• Commercial General Liability (CGL) Insurance: This is foundational. It protects against costly third-party claims, such as accidental injury to a passerby or physical damage to your neighbour’s property due to the work.
• WSIB Coverage (or Clearance): Crucial. It ensures that if a worker is hurt, their medical and wage costs are covered, preventing you from facing financial liability. Always ask for the clearance certificate.
• Pollution and Environmental Liability: This coverage is essential in demolition. It addresses the high-risk issue of discovering or accidentally releasing contaminants like asbestos, lead, or chemical spills, covering cleanup and fines.
• Commercial Automobile Insurance: Provides coverage for all the heavy machinery, excavators, and dump trucks used to perform the work and haul the materials.
