Canada's new tax policy enables certain organizations that buy or build new facilities to write off the cost of expansions on their taxes, and your business likely qualifies. This 100% immediate expensing deduction can save you hundreds of thousands of dollars. This tax benefit only applies to buildings that are operational before 2030, so it's important to act quickly. Here's what you need to know about the new Canada greenhouse tax policy. What Changed in the 2025 Federal Budget for Greenhouse Builders Canada’s 2025 federal budget, tabled on November 4, 2025, introduced new business income tax measures that significantly increase available deductions for greenhouse expansion. These measures were enacted into law through the Budget 2025 Implementation Act (Bill C-15), which received Royal Assent on March 26, 2026. Immediate Expensing for Manufacturing and Processing Buildings The 2025 federal budget provides temporary, immediate expensing of the cost of eligible manufacturing and processing (M&P) buildings, renovations, and expansions. It provides a 100% deduction in the first taxation year for eligible properties to encourage investment in these industries. How the 90% Floor Space Rule Applies to Greenhouses This tax measure applies to buildings that use at least 90% of their floor space to manufacture or process goods for sale or lease. For greenhouses, this means that 90% of the building space must be used for crop production, while space... --- - Published: 2026-04-14 - Modified: 2026-04-15 - URL: https://sef.ca/dt-enterprise-completion/ DT Enterprise Greenhouse Expansion SEF® (South Essex Fabricating) is proud to share the completion of a 7-acre greenhouse expansion for DT Enterprise in Ruthven, Ontario, delivered in partnership with RGC.

Missed approvals halt construction, delay your growing season, and cost far more to fix than to prevent. This guide covers the full stack of commercial greenhouse permit requirements that Ontario growers face, so you can plan ahead and protect your schedule. South Essex Fabricating (SEF) is the turnkey greenhouse builder in Ontario for in-house permit coordination and commercial construction across the province. Give us a call to simplify your project. Why Ontario Growers Must Understand Permits Before Breaking GroundA modern commercial greenhouse triggers a chain of approvals that can take months to process. Missing even one can stop your build or push back your first harvest by an entire season, cutting into revenue for year-round production operations. Securing commercial greenhouse construction approval requires coordinating across provincial ministries and local municipalities simultaneously. Obtaining a commercial greenhouse expansion permit in Ontario adds to those timelines, so mapping out the full process before committing to a budget is critical. What Happens When You Build Without the Right ApprovalsBuilding without the required approvals exposes your operation to stop-work orders, fines, and potential demolition of non-compliant structures. Municipal building officials in Essex County and across Southwestern Ontario review and inspect large agricultural construction projects, and unpermitted structures can void insurance coverage and complicate future financing. Building Permits Under the Ontario Building Code and National Farm Building CodeEvery Ontario greenhouse construction permit... --- - Published: 2025-12-17 - Modified: 2025-12-17 - URL: https://sef.ca/2025-recap/ As 2025 comes to a close, we’re taking a moment to reflect on a year of growth at SEF®.

These systems serve as the structural foundation on which crops grow while also helping manage runoff and nutrient flow. Choosing between open gutter systems and closed gutter systems depends on several factors, including crop type, sanitation requirements, and maintenance preferences. Each system offers distinct advantages and presents unique challenges that growers must consider when planning their greenhouse layout. Closed Gutter System Advantages of Closed Gutters Limited sunlight exposure, significantly reducing the risk of algae growth within the system. Enhanced structural strength, allowing for reliable support. Reduced contamination risks during active crop cycles, as the enclosed design prevents plant debris from entering the gutter. Considerations and Challenges More complex cleaning processes at the end of each crop cycle, as the enclosed design can trap organic residue. Reduced visibility into the system, requiring thorough inspection protocols. Open Gutter System Advantages of Open Gutters Full system visibility, allowing growers to monitor drainage, water flow, and overall gutter conditions in real time. Easier cleaning and maintenance at the end of each production cycle. Considerations and Challenges Increased risk of algae growth due to sunlight exposure. Higher likelihood of clogs, as plant debris—including leaves and produce—can fall directly into the gutter. Greater potential for contamination, particularly if regular cleaning is not maintained throughout the crop cycle. Choosing the Right System Both systems can be effective when matched to the crop type, greenhouse design, and operational goals. Assessing these factors in advance helps ensure... --- - Published: 2025-03-26 - Modified: 2025-03-26 - URL: https://sef.ca/ruthven-farms-greenhouse-expansion/ Project Details SEF® is proud to announce the completion of a 2-acre greenhouse expansion for Ruthven Farms in Ruthven, Ontario.

Our community has undergone a transformative journey, marking pivotal moments in the region's agricultural history. As we look back to the 19th century and compare it to the thriving industry of today, we witness a remarkable tale of growth, innovation, and resilience. Greenhouse Farming History During the 1970s, Leamington witnessed an increase in advancements in greenhouse farming technology, leading to the expansion of commercial greenhouse operations. Tomato and cucumber cultivation dominated the industry, prompting local farmers to innovate new methods for improving crop yields and quality. The growth of the greenhouse sector also spurred the development of supporting industries, such as packaging, marketing, and transportation, further fueling economic expansion. Produce was distributed through the Ontario food terminal in Toronto or directly through produce stands operated by family-owned farms. Another sector experiencing significant growth was R&D. Researchers were constantly seeking out new plant varieties for cultivation, while also focusing on combating diseases and pests. Leading North America in Modern Greenhouse Production Today, Leamington is home to some of the largest greenhouse operations in North America, producing a diverse array of fruits and vegetables year-round.

From churches, to recreational facilities, to office buildings, there are some major advantages to opting for a pre-engineered steel structure when scaling an organization (namely: cost efficiency, durability, and construction timeframes). Under the umbrella of pre-engineered steel buildings, there are two main framing techniques—rigid framing and truss framing—that have their respective advantages and disadvantages. Understanding how these two techniques differ from one another is essential for businesses looking to start work on a new building project. Rigid Frame versus Truss Frame Rigid Frame Steel Buildings There’s a reason why rigid frame systems are the most commonly used framing option in pre-engineered steel buildings: a rigid frame steel structure is one of the most cost-effective steel building solutions that maximizes both structural integrity and use of interior space. Rigid frame steel buildings are characterized by their load-resisting frame design, engineered to be durable even in extreme weather conditions and to ergonomically support the main load-bearing stress points of a structure. With this framing technique, thicker steel is used to reinforce the areas of the building where the greatest stress is applied. A clear span rigid framing system does not have any interior support columns throughout the structure, meaning interior use of space can be fully maximized. This is by far the most appealing element of a... --- - Published: 2023-09-14 - Modified: 2023-11-10 - URL: https://sef.ca/food-science-research/ At the Center for Horticultural Innovation, we believe that food science testing is one of the best ways to learn about and improve upon the flavor, quality, and longevity of greenhouse-grown produce. In our R&D harvest lab, our team runs a wide variety of tests on fresh produce samples to analyze different attributes, such as sugar levels, acidity, and firmness. We are committed to applying what we learn from this important food science research to help our greenhouse partners grow the best tasting and highest quality produce available! Brix & pH Testing Using a food science approach, our team completes Brix testing on produce samples to determine the sugar content in the fruit. To do this, we first need to blend the fruit and turn it into a liquid. We then use a machine to pull the liquid sample into a chamber where the Brix levels are measured. The machine then displays the Brix level of the sugar found in the fruit, which ultimately tells us how sweet the fruit tastes. We also complete similar pH testing to determine a fruit’s acidity levels. By analyzing the sweetness and acidity levels of greenhouse-grown produce, our team remains on the forefront of discovering the next best tasting produce varieties grown within the horticultural industry. Shelf-Life Testing Along with measuring a fruit’s weight and firmness, our team completes in-depth shelf-life testing to check how aging and storage conditions affect the quality of a fruit.
