General contractors in the GTA are most commonly used for renovations, home additions and construction projects that require the skill of various trades. It is recommended for projects where the client is looking to establish a hard cap on costs based consultant and construction drawings already planned out. A general contractor is responsible for providing all of the material, labour, equipment and services necessary for the construction of the project. Duties of the Toronto general contractor include applying for building permits, securing the property, providing temporary utilities, managing personnel, providing site surveying and engineering, disposing and recycling of construction waste, monitoring schedules and cash flows, and maintaining accurate administration records.

In a general contracting agreement, the contract is between the contractor and client. It is then the duty of the general contractor to use their personnel or hire the necessary sub-trades, procure equipment and supplies accordingly, and complete the project on time and on budget. A lot of coordination is required in order to set schedules and develop timelines for material and labour procurement. As such, Toronto general contractors play the role of managers on a given construction project.

Some of the main benefits of hiring a general contractor include the following:

  • General contractors in Toronto & surrounding areas, such as One Oak Construction, operate on a firm contact price, which is approved by the client before on-site work commences. Only unforeseen complications or changes to the scope of work by the client would have an impact on a price change. The client is aware of and must approve any such additions to the cost before they are made, so there are no surprises later on.
  • A dependable general contractor oversees the entire project, from start to finish. They alleviate the responsibility of coordinating trades, ordering supplies and procuring permits from the client. They maintain an effective communication channel with the client, so that the latter has a clear understanding of the progress of work without having to go through various sources.
  • A reliable Toronto general contractor has an extensive network of certified, licensed and insured sub-trades who can be trusted to provide quality work. A professional contractor with years of industry experience would have cultivated their relationships with other licensed sub-trades, and would utilize the specific trade skills necessary to complete the job well.
  • An experienced Toronto general contractor in  has the construction knowledge and skill to understand how every piece of the project fits together, according to legal codes and client usage. They are able to foresee any future complications and implement contingency plans on this basis. This results in a project completed with client needs in mind, which also meet legislative requirements.

A reliable general contractor will be licensed, insured and, in the province of Ontario, carry the necessary WSIB coverage for construction work. One Oak Construction not only meets these requirements, but is also accredited by the Better Business Bureau, and a member of the Toronto Construction Association. One Oak provides general contracting services in residential, commercial, institutional, and retail sectors of Toronto, the GTA and Southern Ontario.


Any construction jobs, from minor renovations to complete new-builds, are considered to be projects. They contain a scope of work, which includes cost, timelines, limitations and objectives. There is a lot of planning, researching and analysing that has to happen before any work starts on the site.


Pre-construction is the first and most essential aspect of any prospective construction project. Whether the project is a renovation, a new-build or an addition, this phase consists of estimating project costs, setting a schedule and foreseeing any possible complications. Our clients gains a clear understanding of overall costing for the projected site, and are able to determine whether the construction cost meets their internal budgets.

Clients generally seek our pre-construction services for two main reasons: they would like to go ahead with a project but require an accurate cost forecast, or they are thinking of a project and would like to understand what the process is for completing the job. At the end of our pre-construction services, One Oak Construction will provide our client with an extensive report which will outline the cost breakdown, the labour and materials required, the timeline for each stage of the project, and any foreseeable limitations.

Our pre-construction services include meeting with the client, evaluating the job site and formulating a budget price and schedule based on client requirements. If the estimated price doesn’t fit the client budget, we will collaborate to value engineer the products and services offered. Therefore, the project will still have a similar look and feel to the original intentions, at a different cost.

One Oak provides the necessary consulting services needed for the budgeting stage by obtaining and analyzing costs from Architects / Interior Designers / Engineering, to estimating the actual construction costs, timelines, permit requirements and other deliverables. One Oak Construction provides pre-construction services in the residential, commercial, industrial and retail sectors of the GTA and Southern Ontario.


It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design-builder or design-build contractor. The design-build procurement route changes the traditional sequence of work; it relies on a single point of responsibility contract and is used to minimize risks for the project owner and to reduce the delivery schedule by overlapping the design phase and construction phase of a project.

Design Build

A typical project would involve the client specifying their must haves based on the site area. These include details such as the number of offices, conference rooms, data and hardware requirements, entrances, security features and others. The design-build contractor would then establish a team of consultants including an architect, as well as mechanical, electrical and structural engineers and site surveyors. Based on the findings of these experts, the design-build contractor creates a plan for the layout design and establishes construction costs that include all the above mentioned consultant fees.

Generally, this budget is set between the client and design-build contractor, and only changes if there is a scope of work alteration required from the clients’ side. The advantage for the client of choosing a design-build contract is that once all the parameters have been established in the beginning of the project, the onus falls on the design-build contractor to maintain the initial budget.

What makes a strong design-build contractor is the ability to envision the full potential of the clients’ space, and efficiently communicate this with the client so that both parties share a common goal. At One Oak Construction, our clients rely on us to provide prompt service, have transparency with our costs, and maintain an environment of trust throughout the design-build process. We provide design-build services in Toronto, the GTA and most of Southern Ontario and take pride in growing meaningful relationships with our clients.


Green Building Technology designs and implements various systems to buildings and homes in order to reduce negative environmental impact. These technologies effectively utilize resources in order to create energy-efficient, cost-reducing solutions that require low-maintenance into the future. Green building solutions can be implemented to new and existing buildings through services such as lighting and HVAC automation, addition of solar panels, changes to the exterior glass and blinds, and many more. They are not only beneficial for reducing the environmental impact, but also employ building controls to maximize energy efficiency and savings for optimized comfort and convenience.

Green Building Technology

For the past decade, a new emphasis has been placed on re-designing and enforcing various systems to buildings and homes in order to reduce negative environmental impact. Designing and implementing a sustainable energy system, such as installing solar panels on the roof of a building or house, can be an investment as well as an environmental benefit. In the province of Ontario, residents who install solar panels are eligible for the Ontario Solar incentive program, which can provide a return of 10% or more on investment. (CanSIA, 2011)

While there are many benefits to using green building technologies in residential and commercial buildings, here are some of the main ones:

  • Green building solutions decrease operating costs going into the future, as the total amount of energy used throughout the home or building decreases dramatically.
  • Implementing green building solutions is environmentally-sound and sustainable, meaning that systems are meant to last well into the future with low maintenance.
  • Some green building solutions can be an investment, as there are many government grants, rebates and programs available to clients who switch-over.

At One Oak, our team will consult, develop and implement custom green building solutions in residential, commercial, institutional, and retail sectors of Toronto, the GTA and Southern Ontario. We bring with us an extensive network of various trade and labour contacts, experienced project managers and the necessary know-how to complete quality and durable projects with minimal inconvenience to our clients. We take pride in the work that we do, and seek to build meaningful relationships with our clients, which are enhanced by trust, transparency and collaboration.


Construction Management or Construction Project Management is the overall planning, coordinating and controlling of a project from start to finish in conjunction with the client. Construction management is a type of contract between the client and contractor, whereby the contractor plays the role of a project manager, representing both the client and the sub-contractors involved. Similar to project management, construction management requires the use of industry knowledge, skills and techniques to ensure that a project is completed successfully. Construction management consists of time and quality management, cost allocation, procurement capabilities, risk management, contract administration and communication proficiency.


Construction Management


In this type of arrangement, One Oak Construction will oversee the entire project on behalf of the client, provide site and labour supervision and maintain an open-cost system with throughout the job. This indicates that our client is always aware of the costing allocated to all aspects of the job (such as engineering, electrical, or plumbing). Furthermore, the client will pay the sub-trades directly, and have a direct contract with each party, while One Oak will take a construction management fee. This is different from most general contracting arrangements where the contractor is paid by the client, and is responsible for covering the costs of their sub-trades. The benefit of construction management to the client is that they have full control over which sub-contractors they want to work with, and they have a clear understanding of the costs associated. Because construction management requires the client to have separate arrangement with all of the parties involved, it is typically better suited for larger-scale projects.

For these types of projects, such as building additions, new builds and major renovations, the client has the benefit of maintaining control over their hired trades while leveraging external expertise from the construction management firm. At One Oak Construction, our construction management services will take our clients from the pre-construction stage, to obtaining materials/permits/labour, throughout the completion of the construction work, and finally to the warranty stage following the project.

One Oak maximises the resource efficiency through the procurement of labour and materials while implementing the proper coordination and control of planning, design, estimating, contracting and construction. One Oak provides construction management services in the commercial, institutional, retail and residential sectors of Toronto, the GTA and Southern Ontario.
