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 September 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.
Flower Shows and Fall Fairs in Ontario in September and October 2026
Several established Ontario events have dates confirmed for the 2026 fall season.
| Event | 2026 Date | Location |
|---|---|---|
| Toronto Flower Market | September 12 & October 10 | Toronto |
| Sunderland Fall Fair | September 15–16 | Sunderland |
| Orillia Fall Fair | October 2–4 | Severn / Orillia |
| Niagara Parks Annual Chrysanthemum Show | Fall seasonal event | Niagara Falls |
Toronto Flower Market officially lists September 12 and October 10 as its two fall 2026 market dates, while Sunderland Fall Fair is scheduled for September 15–16 and the Orillia Fall Fair for October 2–4.
1. Toronto Flower Market
The Toronto Flower Market is one of the strongest options for visitors who want to experience locally grown flowers in the city rather than attend a traditional agricultural fair.
Its 2026 season runs from May through October, with fall markets scheduled for September 12 and October 10 from 10 a.m. to 3 p.m.
The market brings together Ontario growers, florists and other flower-focused vendors, with available varieties changing naturally throughout the growing season.
Where: TD Commons at CAMH, 1001 Queen St West, Toronto
Fall 2026 dates: September 12 and October 10
The September market has already taken place, while the October 10 market remains the main fall date for visitors planning later in the season.
2. Sunderland Fall Fair
The Sunderland Fall Fair returns on September 15 and 16, 2026. The fair combines agriculture, exhibitions, entertainment and community activities rather than functioning solely as a flower show.
For visitors interested in Ontario’s broader agricultural traditions, it provides a different experience from a dedicated floral market. Horticultural exhibits and locally grown plants fit naturally into the fair’s agricultural focus.
Where: 20 Park Street, Sunderland, Ontario
When: September 15–16, 2026
The official Sunderland Agricultural Society site lists the 2026 fair under the theme “Holy Cow, It’s Fair Time.”
3. Orillia Fall Fair
The 176th Orillia Fall Fair is scheduled for October 2–4, 2026 at ODAS Park.
The event celebrates agriculture and community traditions through exhibitions, competitions and other fall-fair activities. It is particularly relevant for visitors interested in the connection between gardening, local agriculture and seasonal Ontario events.
Where: ODAS Park, Severn Township near Orillia
When: October 2–4, 2026
The Orillia & District Agricultural Society has confirmed these dates for its 2026 fair.
4. Niagara Parks Annual Chrysanthemum Show
The Annual Chrysanthemum Show at the Niagara Parks Floral Showhouse is one of Ontario’s best-known recurring fall floral displays.
The exhibition traditionally features large numbers of chrysanthemums in multiple varieties, arranged alongside other plants to create an immersive autumn display. Niagara Parks describes it as its longest-running floral show, with the tradition dating back to 1946.
Because Niagara Parks’ available event pages do not give us a sufficiently clear 2026-specific date range, visitors should confirm the current schedule directly with Niagara Parks before travelling. The event itself remains a relevant fall attraction, but we should not reuse the old 2025 dates as if they applied to 2026.
Flowers to Look for in Ontario During September and October
Ontario’s fall flower season brings a different colour palette from spring and early summer. Availability varies by grower and weather conditions, but several varieties are strongly associated with this part of the year.
- Dahlias can continue producing dramatic blooms into early fall and are available in many colours and forms.
- Chrysanthemums are among the most recognizable autumn flowers and feature heavily in fall displays.
- Sunflowers bring warm yellow and orange tones that work naturally with September arrangements.
- Asters add purple, blue and pink tones as the season changes.
- Roses remain popular year-round for gifting even as seasonal arrangements move toward warmer fall colours.
Toy Florist shoppers looking for seasonal options can browse dahlias, rose bouquets and the wider fall flower collection.
Bringing Ontario’s Fall Flower Season Home
Attending a market or fall fair is one way to enjoy the season, but seasonal flowers can also be incorporated into birthdays, anniversaries, thank-you gifts or home décor throughout September and October.
Rather than trying to reproduce a specific flower-show display, consider the colours associated with the season: deep reds, orange, yellow, burgundy, cream and warm pinks.
For local gifting, September flower delivery can provide additional ideas, while fall arrangements offer an easy transition into Thanksgiving and the rest of Ontario’s autumn season.
Conclusion
September and October offer several ways to experience Ontario’s fall flower season. The Toronto Flower Market provides direct access to local growers, Sunderland and Orillia bring flowers and horticulture into traditional agricultural fairs, and Niagara Parks continues its long-running tradition of seasonal chrysanthemum displays.
Schedules can change between seasons, so checking the official event website before travelling is always recommended.
For those who prefer to enjoy fall flowers at home, seasonal bouquets and arrangements can bring many of the same colours into birthdays, celebrations, gifts and autumn décor.
