What you earn and what it costs to get there.
Grower or section lead
$45,000
Greenhouse worker
$35,000
Head grower or manager
$70,000
Job Bank's closest page covers greenhouse managers, with a national median of $21.80 an hour, about $45,000 a year full time. Head growers at large vegetable operations in Leamington and Delta earn above the top of this range, because one person's decisions control millions of dollars of crop.
$35,000 to $40,000
Greenhouse worker, often just above minimum wage
Almost everyone starts here: planting, pruning, trellising, harvesting. Show up, learn the crop, and you can be running a section within two or three years.
$70,000 and up
The person responsible for the whole crop
A head grower sets the climate, feed and irrigation strategy for hectares of plants. Experienced head growers at big operations earn well above the Job Bank range, and the best of them are recruited internationally.
Tuition, fees, exams and kit. Not rent, food or travel
You can start as a greenhouse worker with no schooling and be paid from your first day, so the low end is genuinely nothing. The high end is a four year horticulture or plant science degree at $11,000 a year plus a provincial pesticide applicator certificate, which is a course and exam costing a few hundred dollars. A two year horticulture diploma at $4,000 to $7,000 a year is the middle route. Plenty of head growers hold a diploma or no credential at all and got there on a decade of crops behind them, which makes this one of the cheapest ways into science based work.
This is one of the cheapest ways into a science-based career. Many head growers have a diploma or no formal credential at all, just a decade of crops behind them.
Year-round work
Unlike field farming, greenhouses run through the winter, so the job is not seasonal.
Indoor work
Warm and dry, though humid and hot in summer.
Fast promotion
Good workers move to grower roles quickly because the industry is short of trained people.
Produce to take home
A small perk, but a real one.
Housing on some sites
Large operations in rural areas sometimes provide accommodation.
The exact path from high school to qualified.
Start on the floor, learn the crop, take courses that let you make decisions.
High school diploma
Grade 12
Biology and chemistry help. A summer job at a greenhouse or garden centre helps more.
Greenhouse worker
1 to 3 years
Planting, pruning, pollination, harvesting and packing. You learn what a healthy crop looks and smells like.
Horticulture diploma (optional)
2 years
Two years at a college such as Niagara, Olds, Kwantlen or Dalhousie covers plant science, greenhouse climate and pest management.
Grower or section lead
3 to 6 years in
You take responsibility for a block of the greenhouse: irrigation, feed recipe, pest scouting and yield.
Head grower
8 years or more
Climate strategy for the whole site, crop planning with the sales team and managing the growing staff.
Biology
Plant growth, pollination and disease.
Chemistry
Nutrient solutions are chemistry you mix every day.
Math
Feed rates, yields per square metre and climate data.
Computer courses
Modern greenhouses are run through climate control software.
Shop
Irrigation lines, pumps and fans break constantly.
Anyone can be called a grower. What is controlled is what you spray. Ontario requires training and certification to buy or use many pesticides, including a specific farmer certification route for people applying products on their own operation, and every province has an equivalent. Food safety programs that buyers demand also set rules on records, water testing and worker hygiene. Break those and the retailer stops buying, which matters more than any licence.
Ontario
Niagara College, which runs a teaching greenhouse and a horticultural and environmental sciences innovation centre, plus the University of Guelph and Fanshawe College.
British Columbia
Kwantlen Polytechnic University and the University of the Fraser Valley.
Prairies
Olds College in Alberta and Assiniboine College in Manitoba.

Things you don't need, but that help.
Pesticide applicator certificate
Provincial course and exam. Needed before you can apply most crop protection products.
Integrated pest management
Releasing predator insects instead of spraying. Standard in Canadian vegetable greenhouses and a specialist skill.
Climate computer training
Learning a system such as Priva or Hoogendoorn is what turns a worker into a grower.
Hydroponics and irrigation
Mixing and managing nutrient solutions for crops grown without soil.
Cannabis production
A licensed and well paid branch of greenhouse growing with extra security and record keeping rules.
Forklift ticket
Cheap, one day, and useful on every site.
Basic mechanical skills
Pumps, fans, boilers and irrigation lines.
A second language
Many greenhouse crews include seasonal workers from Mexico and the Caribbean, and Spanish is genuinely useful.
Data skills
Growers track yield, light and climate data weekly and argue about it with spreadsheets.
Day to day, pros and cons, where you'd work.
You walk the crop first thing, looking at the top of the plants, the fruit set and the leaves for early signs of pests or disease. Then you check the climate computer and overnight data: temperature, humidity, light, irrigation and drainage. You adjust the feed recipe and set points, meet the crop staff about what needs pruning or picking, scout for pests and release beneficial insects. Afternoons are packing schedules, orders and fixing things that broke.
The good
The hard parts
Things people don't tell you.
Ontario Greenhouse Vegetable Growers states that Ontario is North America's largest producer of greenhouse produce. Tomatoes, cucumbers and peppers are the three main crops, concentrated around Leamington and Kingsville.
Greenhouse tomato growers buy boxes of bumblebees and release them inside. The bees shake pollen loose in a way hand pollination cannot match, and you can tell a visited flower by the small bruise the bee leaves.
Instead of spraying, Canadian vegetable greenhouses release predator mites and parasitic wasps that eat the pests. Growers order them by the container and scout weekly to check they are winning.
A greenhouse tomato vine can grow more than 10 metres over a season. Growers lower and lean the vines along the row so the picking height stays the same while the plant keeps climbing.
