Greenhouses for Sale in Canada
Arctic Acres is our exclusive Canadian manufacturing partner for the original Growing Dome® greenhouse. The Canadian company manufactures its kits in Portland, Ontario, under licence from Growing Spaces, with design and component adaptations for use in Canada.
A greenhouse gives you more time with the garden, whether you want an earlier vegetable harvest or somewhere to care for favourite plants through winter. The size and equipment can reflect how you want to use that space, along with the growing conditions in your part of Canada.

Why choose a Growing Dome for Canadian growing?
The Growing Dome brings climate management into the greenhouse design. Sunlight enters through multiwall polycarbonate, and water in the above-ground pond absorbs warmth during sunny periods. As the air cools, the water releases some of that stored heat, moderating the swing between day and night. Reflective insulation along the north side helps direct radiant energy back into the growing space.
In summer, shade limits incoming heat while ventilation releases warm greenhouse air. Arctic Acres equips its Canadian kits with intake and exhaust fans in place of the automated greenhouse vents used in our U.S. kits.
The rounded shell lets wind move around the greenhouse, while the interconnected triangles distribute structural loads through the frame. The foundation and engineering still need to match local wind and snow requirements. Arctic Acres' component guide describes the Canadian construction and equipment.

Choosing a size for the way you want to garden
The 15-foot and 18-foot kits offer a compact home garden. Moving to 22 feet or 26 feet gives more room to combine annual beds with permanent plants, a potting area, or a chair beside the pond. A school or shared growing project may benefit from the larger 33-foot and 42-foot footprints.
The pond and paths occupy part of every interior, so total floor area is not the same as planting space. Arctic Acres can help compare the sizes around the plants and activities you want room for.
Greenhouse growing across Canada's provinces and territories
A greenhouse has different advantages in different parts of Canada. Near the coast, shelter from cool rain may be as useful as frost protection. Farther inland, gardeners may be looking for more growing time on either side of a short outdoor season.
British Columbia: wet coastal gardens and colder interiors
On Vancouver Island and the Lower Mainland, mild, wet winters make shelter from rain valuable alongside warmth. A covered garden offers a place to tend plants when outdoor beds are soaked. Drainage around the dome and air movement inside help manage those damp conditions. Interior and northern B.C. gardeners face colder winters and, in many areas, a shorter frost-free season, making cold-weather protection a larger part of the purchase.
Alberta, Saskatchewan, and Manitoba: more time before and after frost
Across the Prairies, a late spring frost or an early autumn freeze can interrupt an otherwise productive garden. An enclosed growing space makes it possible to protect crops beyond those outdoor limits, with added heat as needed. The pond helps retain some of the warmth collected on sunny days as evenings cool. In an open rural setting, the dome's rounded shape is also useful for wind exposure, with anchoring and foundations designed for the local conditions.
Ontario and Quebec: winter protection and humid summers
Southern Ontario and Quebec have warm, humid summers as well as cold winters. A Growing Dome needs to shed summer heat as deliberately as it collects warmth in colder months. Fans and shade are part of that seasonal change. Conditions also vary within each province: a Niagara garden and a garden farther north will have different outdoor seasons, and trees or neighbouring buildings can greatly reduce the low winter sunlight reaching either greenhouse.
Atlantic Canada: shelter for cool-season growing
For gardeners in Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador, a greenhouse can provide shelter from cool rain and coastal wind while allowing more control over warmth and watering. Newfoundland and Labrador's short, cool growing season makes an earlier start particularly useful. Inland snowfall and exposed coastal locations need different structural consideration when Arctic Acres and local professionals review a project.
Yukon, the Northwest Territories, and Nunavut: making use of northern daylight
Long summer days offer a valuable growing window in the North, even where the outdoor season is brief. A dome can provide protected space for seedlings and food crops during those months. Growing through the darkest part of winter is a different undertaking: heating and supplemental lighting become central to the project. Arctic Acres can discuss the intended season and delivery options with households and community groups.
The Canadian greenhouse archive includes gardens and community projects that show how owners have adapted the Growing Dome to different parts of the country.
A longer growing season or a year-round greenhouse?
A greenhouse used from early spring into late autumn can be a substantial change for a Canadian garden. Keeping it productive through winter is a further choice. Hardy vegetables can tolerate cooler conditions than tender flowers or fruiting crops, while a winter harvest also depends on how much light reaches the plants.
The Growing Dome's passive-solar features help make use of available sunshine. Supplemental heat depends on the winter climate and the temperatures your plants need; short days and cloud cover can also limit growth even in a warm greenhouse. If you want a comfortable place to sit among the plants, that temperature preference belongs in the equipment discussion too.

An Ontario greenhouse filled with flowers, fruit, and experiments
Ron Cole built his 15-foot Growing Dome in Ontario in 2014. Inside, curved raised beds and a second pond made the small space his own. He added string lights, and the greenhouse glowed in the garden at night.
His first plantings focused on vegetables, but a peach tree soon had him returning with a paintbrush to pollinate the blossoms. In our 2020 story, his plant collection included grapes, a fig tree, hydrangeas, and gerbera daisies. A small heater helped keep the greenhouse warm enough for flowers through winter; Ron told us about a rose that bloomed on Christmas Day.

Growing fresh food in northern communities
In Naujaat, Nunavut, Green Iglu began its 2015 pilot with two 42-foot Growing Domes. Growing Spaces helped build the greenhouses, and the local community took over the project in 2018.
Our 2022 story also follows projects in British Columbia, Quebec, and Newfoundland and Labrador. Training and community participation accompanied the structures, helping people grow fresh food close to home.

Buying, delivering, and assembling a Canadian Growing Dome
Arctic Acres has been our licensed Canadian partner since 2019 and makes its kits in Portland, Ontario. Their team supplies the Canadian purchase quote and assembly guidance, and arranges shipping across Canada. Remote destinations may need additional freight arrangements, which can be discussed while the model is being chosen.
The kits are designed for owner assembly, and customers can also hire a local builder. Arctic Acres provides manuals and videos, with experienced contractors available for some larger or community projects. Availability depends on location and schedule. Foundation work, locally purchased materials, and any additional engineering need to be included in the overall budget.
Arctic Acres' getting-started guide explains Canadian foundation options and owner-supplied materials. Local authorities and project professionals confirm the permit and structural requirements for the intended use. Arctic Acres can provide its plans and help identify what needs further review.
