Hexagon is a Michelin-starred French restaurant in Oakville, Ontario, Canada.
The business was opened in September 2017 by restauranteur Artur Koczur, who previously operated a cafe in the same space. Koczur sold the business in spring 2023 to new ownership.
Between 2018 and 2025 the restaurant's kitchen was headed by Rafael Covarrubias, who started as the sous-chef in 2017 before becoming executive chef a year later. Covarrubias announced his departure as chef effective December 2025, to take on the role at fellow Toronto-area Michelin-starred restaurant 20 Victoria. Hexagon's chef de cuisine and sous-chef also departed to join Covarrubias at 20 Victoria.
As of March 2026 and following the departure of Covarrubias, the restaurant has been temporarily closed while ownership seek to reboot the restaurant concept.
The restaurant has an open kitchen and offers a tasting menu.
The interior of the restaurant incorporates several design elements inspired by its namesake, the hexagon.
During the tenure of Covarrubias as head chef, the restaurant's cuisine used French techniques while drawing from Covarrubias' Mexican roots.
The restaurant received a Michelin star in the 2024 edition of the Toronto and Region Michelin Guide, and retained its star in 2025. It is the first and only restaurant in Toronto's suburban Halton Region to receive a Michelin star. Head chef Covarrubias was also recognized at the 2024 ceremony with the 'Michelin Young Chef Award' for the region.
