About the venue

The site is across from the Metro Toronto Convention Centre and about a two-minute walk from the GO and UP Express station. A full-venue buyout is offered for outdoor events of up to 6,000 attendees.

On EventPlans.ca it is listed as a winery or brewery and unique venue in Toronto, at 255 Bremner Blvd., Toronto, ON.

The venue lists these spaces. Capacities are the venue’s own figures and change with the layout you choose.

  • Locomotive Hall: up to 800
  • Pilsner Hall: up to 350
  • The Tap Room: 75 seated dinner, 180 cocktail reception

Capacity

The venue does not publish a single maximum for every room, so ask for the capacity of the specific space in the layout you want: seated dinner, standing reception, theatre or classroom.

A useful rule: a seated dinner at rounds of ten needs about 1 to 1.2 square metres per guest, a standing reception about 0.7, and theatre seating about 0.6, before you add a stage or dance floor. The venue capacity calculator does the arithmetic for your room.

Events it hosts

According to its own event pages, the venue hosts weddings, corporate events, galas and fundraisers and private social events.

Questions to ask on your site visit

Bring these to your walk-through. Get the answers in writing before you sign.

  • Which spaces are used if the weather turns on the day?
  • Must all alcohol be bought from the venue, and how is it charged?

  • Are tents allowed, and who supplies them?
  • Does the production area stay open during your event?

Planning entertainment here

Barrel rooms and patios suit acoustic music and roaming entertainment. Outdoor sound usually has an end time, so plan louder entertainment indoors.
