Where to Buy Plants in the GTA: Garden Centres Worth the Drive

A garden centre earns a drive when it can tell you what the plant tag cannot: who grew this, and what happens if it dies. Four GTA retailers publish that they grow much of their own stock (Sheridan Nurseries, TERRA Greenhouses, Valleyview Gardens in Markham and Vandermeer Nursery in Ajax), and each backs it with a written guarantee whose conditions decide whether it is worth anything. Native plants are a separate trade on a shorter season, and the cheapest trees in the region are not sold at a garden centre at all.

Grower or reseller: the distinction that decides the drive

Most garden centres buy in finished plants and sell them; a grower raises them. Each of the four describes its own operation:

Sheridan Nurseries, founded in 1913 near Sheridan, Ontario (now part of Oakville), farms over 900 acres at Glen Williams and Norval, grows over 1,200 cultivars of perennials and hardy nursery stock, and ships over 1.8 million plants a year. Seven of its eight garden centres are in the GTA, the eighth being Kitchener. It describes its Southdown Road store as one of the largest combined retail and trade garden centres in Canada, and the store it lists as "Etobicoke" has a published address of 2069 Burnhamthorpe Road East in Mississauga.

TERRA Greenhouses runs five acres of production behind five retail garden centres with, it says, full production capability, so that customers "can shop directly from some of the benches we grow on." Three of the five are in the GTA, counting Burlington in Halton; the two nearest Toronto are Vaughan at 11800 Keele Street and Milton at 12800 Britannia Road, which TERRA calls its largest store.

Valleyview Gardens has been in Markham since 1970, now at 8636 Reesor Road on the north side of Highway 7. It grows year-round from tissue culture, grafted branches and hand-cut propagations, and is unusually specific about what: one of Canada's largest producers of calamondin citrus, over 30,000 hot pepper plants a year from seed, and pothos propagated in bulk from its own mother plants.

Vandermeer Nursery at 588 Lake Ridge Road South in Ajax is in its second and third generation after more than 60 years, and says plainly that it grows most of what it sells at its Ajax greenhouses, hardening perennials and shrubs off to the local outdoor climate first.

The guarantee is the part you can actually check

All four publish a plant warranty. Put the same four questions to each (how long, does a pot count, when can you claim, what must you produce) and the headline number stops being the interesting part.

Outside trees and shrubs, Sheridan gives roses one year and non-flowering houseplants three months, while annuals, hanging baskets, herbs and vegetables, bulbs, seeds, bonsai and flowering houseplants including orchids get nothing. Its two discount rules are easy to blur: Manager's Specials, seasonal clearance and anything discounted 50 per cent or more stay warrantied, but only to the value paid on a gift card rather than by replacement, while Farm Sale items and price points ending in .00 are final sale and not covered at all.

Vandermeer's two years cover hardy evergreens, deciduous trees and shrubs and hardy vines, except boxwood, clematis, Japanese maples, rhododendrons, azaleas, pieris and anything marked tender, which drop to September 30 of the year of purchase, as do perennials, roses and hardy water plants. It also excludes plants never taken out of their original pot, frost damage, and death from improper planting, over- or under-watering and animals.

Valleyview's year runs against a named list of 45 plants (cedar, spruce, magnolia, hydrangea and lilac among them), which it describes as select perennials with woodier stems. Annual, tropical and perennial stock is not guaranteed, roses, rhododendrons and azaleas are not covered over winter but only to the end of October in the year of purchase, discounted and wholesale purchases are excluded, and stock is replaced once.

TERRA's policy, last updated November 29, 2023, warrants trees, shrubs, evergreens and vines for one year from purchase, but roses, perennials and ground covers only to December 31 of the year of purchase, and it excludes anything bought under the Landscaper's discount programme.

Native plants run on a shorter calendar

The growers above stock some natives, but the specialists are separate businesses with short seasons. The Halton Region Master Gardeners' March 2026 list of Southern Ontario native nurseries opens with an instruction worth repeating: "Contact the nursery in advance. Many have limited hours, or are open by appointment only."

Three that serve the GTA:

• **Toronto Plant Market and Native Plant Supply**, 327 Bering Avenue in Etobicoke. Open for the season April to October, Wednesday to Friday 11am–6pm and weekends 9am–2pm, stocked from local growers and verified seed, per the Bee City Canada nursery directory.
• **Native Plants in Claremont**, 4965 Westney Road in Pickering. Ontario wildflowers, trees, vines, shrubs and ornamental grasses, with boxed potted plants couriered by FedEx within Ontario. The sources disagree on the days: the Halton list gives late April to mid-October, Wednesday to Saturday, the nursery's own site Thursday to Saturday 9am–3:30pm and Sunday noon–3pm. The Halton entry settles it, because its comment reads "Check out website".
• **Ontario Native Plants**, online only, shipping within Ontario by UPS with delivery in two to seven days. Every plant is propagated from seed collected in Ontario and sold as a plug 2.5 inches wide and 5 inches deep. The FAQ is pointed about why: seed-grown plants are not clones, so each has its own genetics. Stock sold between July and September is current-year, roughly 4 to 5 months old and 15 to 30 cm tall. Its own banner sets the last day for orders this season at September 18, with preorders for next year opening February 27, 2027.

The North American Native Plant Society runs an annual native plant sale at the Toronto Botanical Garden, but its site still shows the 2026 date, Saturday May 9, which has passed, and marks online advance ordering finished, so watch it for a 2027 date rather than treating it as a live listing.

The cheapest trees in the GTA are not at a garden centre

If you want a tree, start with the subsidised programmes: no retailer competes with them.

The Toronto Free Tree Program gives Toronto residents up to two free native trees or shrubs per household each spring and fall, in 1 or 2-gallon pots and 1 to 4 feet tall, collected at pickup locations that move each season. Preregistration is required, and the plant has to go on privately owned land. The City warns that part of your front or side lawn may be road allowance, which does not qualify. As of the page's July 19, 2026 update, the spring pickups had ended and fall dates were not yet posted.

Above that sits LEAF, the non-profit the City has partnered with for subsidised planting on private property. Full service buys a 30-minute site consultation with an arborist, a 5 to 8 foot native deciduous tree or a 2 to 4 foot native evergreen, delivery, planting, mulch and a care guide, for backyards and fenced side yards only; the do-it-yourself option swaps the site visit for a virtual consultation, delivers the tree and mulch to your door, covers front and unfenced side yards, and leaves the digging to you.

Three conditions decide whether this is for you. First, geography: LEAF's private-property service area is Toronto, nine York Region municipalities and six in Durham. No Peel or Halton municipality is on it, though LEAF runs a separate Halton Hills native tree and shrub sale. Second, municipal top-ups: Markham residents pay $100 for a deciduous tree and $50 for an evergreen from a select species list, capped at five trees per property per year; Newmarket adds a $100 rebate, not for business properties; Ajax adds $150 on full service or $100 on do-it-yourself; Newmarket's and Ajax's are one rebate per property per year, first come first served, space permitting. Toronto residents in eligible low-canopy, equity-deserving neighbourhoods may qualify for free trees and shrubs outright.

Third, and easiest to miss: the site consultation is not free unless you buy a tree. Leave without one and LEAF charges $100 (+HST). That fee is deducted from the cost of a tree order "provided no species or location changes have been made", but ordering only shrubs or cedars does not redeem it: their cost is added to the $100 you have already paid.

The Ontario Native Plants endpoints are ours, not the nursery's: on its shop page on 26 August 2026 the 129 listings ran from $7.00 for Little Bluestem and eight other grasses and sedges up to $11.50 for Pawpaw. Price in LEAF's condition too: its guarantee expects you to water each tree or shrub twice a week, roughly six gallons, for the first two years.

When to go, and how the plants get home

Timing decides half of it. The Toronto Master Gardeners' seeding dates for Toronto put frost-hardy crops such as lettuce, peas and spinach in the ground from April 15 to 25 and tender transplants (cucumbers, peppers, squash) not until May 25 to June 5, so anything tender bought earlier has to live somewhere frost-free until then.

Hours are the other planning problem, and they vary by store rather than by chain. Valleyview is open every day of the year except Christmas Day, Boxing Day and New Year's Day, but says its hours change seasonally. Vandermeer runs 8am to 8pm on weekdays and 8am to 6pm at weekends, and opens on every holiday except Christmas Day, New Year's Day and Family Day. TERRA's Milton store posts 10am to 7pm Monday to Friday and 10am to 6pm at weekends; the other locations publish their own.

If the plants will not fit in the car, Valleyview delivers anywhere in the GTA from $95 plus HST, usually within two weeks, with no guaranteed date in spring and summer. Vandermeer delivers larger orders from Cobourg to downtown Toronto to Uxbridge, but asks you to come and choose the plants in person first. Both repot free with conditions: Valleyview when you buy the plant, pot and soil together, Vandermeer when you buy a houseplant and a decorative pot at the same time, with orchids, bonsai and carnivorous plants treated as chargeable specialty work. Valleyview also gives 10 per cent off to anyone over 65 on Wednesdays and to garden club members any day, on non-sale items, if you say so before paying.

Check the listing before you drive

Garden centre round-ups go stale fast, and Humber Nurseries is the cautionary case. It closed its Brampton retail operation after 59 years, final day October 31, 2019, and reopened in Caledon as a wholesaler. It now trades as Humber Nurseries 2020 Ltd. at 14905 Bramalea Road, calls itself a wholesale grower and supplier, and takes retail inquiries by email request. The humbernurseries.ca domain belongs to an unrelated Humber Nurseries Limited in Corner Brook, Newfoundland, so a search result under that name is not the business an old list is sending you to.

One destination costs nothing to browse. The Toronto Botanical Garden keeps its outdoor gardens open daily from dawn to dusk with free admission, and posts hours of operation of 9 a.m. to 4:30 p.m., Monday to Sunday. Parking is $4 per hour to a maximum of $16 per day and free for members; memberships start at $60 a year. It is the cheapest way to see mature plantings labelled with the botanical names the native nurseries want you to order by.
