Top Flower Shows in Ontario 2026: September and October Events
Ontario’s floral season does not end with summer. September and October bring late-season blooms, fall colours, local flower markets, agricultural fairs and seasonal displays across the province.
For flower lovers, these months offer a chance to see chrysanthemums, dahlias, sunflowers, asters and other autumn favourites while supporting local growers and community events. Some events focus specifically on flowers, while others combine horticultural exhibits with broader fall-fair traditions.
If you are planning something closer to home, you can also explore our October flowers guide for seasonal flower ideas or browse fall flowers inspired by the colours of the season.
Why September and October Are Great Months for Flower Events in Ontario
Early fall sits between two growing seasons. Many summer varieties are still blooming in September, while chrysanthemums, asters and other autumn flowers become more prominent as temperatures cool.
It is also an important time for local flower growers and agricultural communities. Markets continue to feature locally grown blooms, while fall fairs bring together gardening, agriculture, food and community traditions.
Because individual event schedules can change from year to year, visitors should always check the organizer’s official website before travelling.

1. Toronto Flower Market
Toronto Flower Market brings together local flower growers, florists and other members of Ontario’s floral community at TD Commons at CAMH.
The market runs monthly from May through October, with different locally grown flowers available as the season changes. By early fall, visitors can expect the selection to reflect the transition from summer blooms toward richer autumn colours and seasonal varieties.
The September 12 market has already taken place. The final Toronto Flower Market date of the 2026 season is scheduled for October 10.
Where: TD Commons at CAMH, 1001 Queen Street West, Toronto
2026 fall dates: September 12 and October 10
Hours: 10 a.m. to 3 p.m.
The market is a useful stop for people interested in seeing what Ontario growers are producing locally at this point in the season.
2. Sunderland Fall Fair
The 2026 Sunderland Fall Fair took place on September 15 and 16. The event combines agriculture, exhibitions, entertainment and community activities rather than functioning solely as a flower show.
For visitors interested in Ontario’s broader agricultural traditions, the fair includes exhibits featuring flowers, vegetables and other locally produced entries alongside livestock shows, homecraft competitions, food, art and entertainment.
Where: 20 Park Street, Sunderland, Ontario
2026 dates: September 15–16
The Sunderland Agricultural Society celebrated the fair under the 2026 theme “Holy Cow, It’s Fair Time.”
Although the 2026 event has already finished, Sunderland Fall Fair remains a good example of how flowers and horticulture form part of Ontario’s wider agricultural-fair tradition.
3. Orillia Fall Fair
The 176th Orillia Fall Fair runs from October 2–4, 2026 at ODAS Park in Severn.
The fair celebrates agriculture and community traditions through exhibits, competitions, livestock, local vendors, midway attractions and live entertainment.
Its competitive exhibits also include flowers, vegetables and crops, connecting the event directly with Ontario’s fall growing and harvest season.
Where: ODAS Park, 4500 Fairgrounds Road, Severn, Ontario
When: October 2–4, 2026
Alongside horticultural exhibits, visitors can expect agricultural activities such as animal shows, homecraft displays and other family-oriented fair attractions.
Anyone planning to attend should check the organizer’s current daily schedule before travelling, as individual activities and show times can vary by day.
4. Niagara Parks Annual Chrysanthemum Show
One of Ontario’s most established fall floral displays takes place at the Floral Showhouse in Niagara Falls.
The Annual Chrysanthemum Show is Niagara Parks’ longest-running floral exhibit. For the 2026 season, the extended five-week show opens on October 9.
The display features approximately 1,350 chrysanthemums across 35 varieties, complemented by around 200 additional display plants. The design uses traditional autumn shades alongside pink, orange, yellow and purple blooms.
Chrysanthemums are especially associated with the later part of Ontario’s growing season, making this display particularly relevant for visitors interested in fall flower varieties.
Where: Floral Showhouse, Niagara Falls
2026 opening: October 9
Duration: Extended five-week seasonal display
Because Floral Showhouse programming and admission details may change, visitors should confirm current hours and ticket information through Niagara Parks before travelling.
What Flowers Can You See in Ontario During Early Fall?
The exact selection changes according to weather, location and growing conditions, but September and October can feature a mix of late-summer and autumn flowers.
Chrysanthemums
Chrysanthemums are among the most recognizable fall flowers in Ontario. Their peak seasonal association with autumn makes them common in gardens, displays and fall arrangements.
The Niagara Parks Chrysanthemum Show offers one of the clearest examples of how varied these flowers can be, with multiple cultivars, colours and display forms.
Dahlias
Dahlias can continue flowering into early fall before colder temperatures and frost bring their outdoor season to an end.
Their wide range of forms and strong colours make them popular for both gardens and seasonal floral arrangements.

Sunflowers
Sunflowers are strongly associated with late summer and early autumn. Depending on the variety and growing conditions, they may continue appearing at farms, markets and seasonal displays into September and early October.
Their warm yellow and golden tones also work naturally with traditional fall colour palettes.
Asters
Asters are another important late-season flower. Their purple, blue, pink and white blooms can provide colour after many summer flowers begin to fade.
They are also useful plants for pollinators during the later part of the growing season.
Flower Market vs. Agricultural Fair vs. Floral Show
Not every event on this list offers the same experience.
A flower market, such as Toronto Flower Market, focuses primarily on local growers, florists, cut flowers and floral products.
An agricultural fall fair, such as Sunderland or Orillia, covers a much broader range of activities. Flowers and horticultural exhibits appear alongside livestock, crops, food, entertainment and community competitions.
A dedicated floral show, such as Niagara Parks’ Chrysanthemum Show, places much greater emphasis on designed plant and flower displays.
Knowing the difference can help you choose the event that best matches what you want to see.
Tips for Visiting Ontario Flower Events in Fall
Fall weather in Ontario can change quickly, especially as October progresses. If an event has outdoor sections, check the forecast and dress appropriately.
It is also worth checking the organizer’s website on the day of your visit. Event hours, individual attractions and schedules can change.
For flower markets, arriving earlier may provide a wider choice of locally grown blooms. Agricultural fairs may have different competitions and entertainment scheduled throughout the day, so reviewing the program in advance can help you plan your visit.
For larger seasonal displays such as Niagara Parks’ Chrysanthemum Show, checking current admission and opening hours before travelling is especially useful.
Bringing Ontario’s Fall Flower Season Home
You do not need to attend a flower show or fall fair to enjoy the colours of the season.
Autumn floral arrangements often use warmer shades such as orange, yellow, burgundy, red and soft neutral tones. The exact flowers available can vary throughout the season, so arrangements may change based on current inventory.
For more seasonal inspiration, explore our October flowers guide or browse our fall flower collection.
You can also explore rose bouquets if you prefer a more classic floral gift that is not limited to a specific fall event or flower variety.
Final Thoughts
September and October offer several ways to experience Ontario’s fall flower season.
September events such as the Sunderland Fall Fair and the September Toronto Flower Market date have already finished for 2026, while October includes the Orillia Fall Fair from October 2–4, the final Toronto Flower Market of the year on October 10 and Niagara Parks’ annual Chrysanthemum Show beginning October 9.
Together, these events show different sides of Ontario’s floral season, from locally grown cut flowers and agricultural exhibits to large-scale seasonal displays.
Because schedules can change, always confirm dates, hours and admission information directly with the event organizer before travelling.
For those who prefer to enjoy the season at home, fall bouquets and arrangements can bring the colours of Ontario autumn into birthdays, celebrations, gifts and home décor.
