- Architectural plan
- A floor plan or technical drawing to scale, showing the relationships between rooms, spaces, structures, traffic patterns and other physical features at one level of a structure.
- Building permit
- A document issued by the City of Toronto that provides formal permission to begin construction (demolition, addition, renovation, etc.) on your property.
- To obtain a building permit, the City of Toronto must review your plans to ensure compliance with Ontario building codes, local bylaws and other applicable laws. For more information, visit the City of Toronto website.
- Civil plan(s)
- The approved engineering plan(s) for the design, construction and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways.
- Composite utility plan
- A document that shows the location of all proposed utility systems, including, but not limited to, electrical, telecommunications, natural gas and municipal services.
- Electrical room floorplan (also known as an electrical room plan or electrical drawing)
- A construction drawing that shows the details of an electrical supply from the power source to each electrical output in a building, making it easier for both Toronto Hydro designers and the contractors to understand what’s required.
- A typical electrical room floorplan includes a cable routing diagram, a site plan showing incoming utility services and substations, a symbols and abbreviations list, quotations, service size, panel load schedules and equipment load schedules.
- Electrical Safety Authority (ESA) permit
- The ESA is responsible for enforcing a level of public electrical safety across Ontario. After a customer has electrical work completed, they’re required to have an ESA inspection completed to ensure it meets the requirements defined in the Ontario Electrical Safety Code, which sets provincial standards for safe electrical installations and electrical products.
- Once the inspection has been successfully completed, the ESA will issue a permit authorizing Toronto Hydro to energize (or re-energize) service.
- Electrical site plan
- An electrical drawing that shows the placement of electrical equipment and its connections, as well as electrical equipment descriptions, power rating(s), voltage(s), size(s), capacity and more.
- Engineering plan(s)
- Plans and specifications certified by an engineer or architect licensed to practice in Ontario, in accordance with the rules of the jurisdictional engineering board, land surveying examining board or architectural examining board.
- Load calculations
- Electrical load calculations help determine a property’s electrical-use threshold. Load calculations must meet requirements outlined by the Ontario Electrical Safety Code.
- Parcel register
- An official electronic report from the Ontario government pursuant to provincial land registration statutes. It presents the property's legal description, the PIN (Property Identification Number) and the registered owner(s) of the property, including the ownership percentage(s) and type of ownership.
- Single line diagram (SLD)
- A simplified representation of an electrical system that shows how electricity flows from the power source to distribution equipment. It is also commonly referred to as an SLD or a one line diagram.
- Site grading plan
- A construction drawing that illustrates the grading layout of a site. The plan should include proposed grading, compliance with zoning and other regulatory requirements, environmental protection from stormwater run-off, potential pollutants and erosion, and desired property aesthetic.
- Site plan
- A drawing used to show the land base (ground-level) key elements of the site, including pedestrian, bicycle and vehicular circulation, hard and soft landscaping, and grading, both onsite and in context with adjacent streets, boulevards and properties.
- The site plan includes a significant amount of information and detail, and will be reviewed together with other detailed drawings.
- Site servicing plan
- A scale drawing used to show existing and proposed changes to the various utilities onsite, including grade changes, driveway crossings with dimensions from property lines, curbs, gutter sidewalks and onsite parking.
- Sketches of asset(s) in conflict
- One or more simple drawing(s) containing relevant detail markings that do not need to be to-scale or mathematically precise, but sufficiently convey ideas or proportion of hydro plants that are in conflict for which a customer requests remedy. These could include pictures with added markings and notes or drawings with some added dimensions for reference.
- Suite metering provider
- A document that provides details about the suite metering provider or sub-metering provider that would be, or currently is, providing suite metering services to customers from a bulk meter supplied by Toronto Hydro.
- Transfer switch specifications
- A document that specifies where transfer switches are located (before or after the meter base). This helps determine the point of connection between the generator and the premise.
- Utility Clearances for Demolition Permit (demolition permit)
- A permit to demolish an existing structure (must be completed and signed by the owner).
- Zoning Applicable Law Certificate Program (ZAP)
- A document provided by the City of Toronto after a preliminary review of submitted plans has taken place to confirm zoning and applicable law compliance. For more information, visit the City of Toronto website.
