Couples comparing intimate countryside options may come across the Millcroft Inn wedding venue in Caledon. Located in the village of Alton, Millcroft Inn & Spa is a historic hotel and spa with indoor and outdoor ceremony and reception settings. Its official wedding information confirms a maximum wedding capacity of 80 guests, in-house food and beverage service, planning support and accommodations on the property.
The setting combines a nineteenth-century mill building with surrounding woodland, the Mill Pond and nearby falls. This profile summarizes only details documented by Millcroft Inn & Spa and was last reviewed on August 5, 2026. Couples should obtain a current, date-specific proposal before making budget or availability decisions.
Millcroft Inn & Spa hosts wedding ceremonies and receptions, with options for indoor celebrations and outdoor settings. The wedding team includes a Wedding Sales Manager during the initial vision and booking stage, followed by a dedicated Special Events Manager who guides the details and oversees the wedding day.
Food and beverages are prepared and supplied in-house. The official package description includes a custom dinner menu, a selection of hors d’oeuvres and a wedding bar package. Clippings Floral Design, described by the venue as its in-house florist, can also create custom flowers and décor.
The River Room is a private indoor banquet room for ceremonies or receptions and hosts up to 80 guests. Millcroft’s Riverside Wedding Garden also hosts up to 80 and sits near the Millpond and falls. Headwaters Terrace accommodates up to 40 guests and can be used for ceremonies or receptions overlooking the Mill Pond.
The overall published wedding maximum is 80 guests. Couples should ask whether their preferred room capacity changes with the proposed dining layout, dance floor, entertainment equipment or accessibility requirements.
The property is at 55 John Street in Alton, within the Town of Caledon. Millcroft describes its location as approximately 60 minutes northwest of Toronto, making it a possible destination for couples considering a countryside hotel venue outside the city. Actual travel time will depend on traffic and guests’ departure points.
The documented capacity and accommodation, restaurant and spa facilities may suit couples planning a celebration of 80 guests or fewer who want the ceremony, reception and overnight stay at one property. Headwaters Terrace provides a smaller option for events of up to 40 guests.
Documented features include three distinct wedding settings, indoor and outdoor options, on-site accommodations, 150 complimentary parking spaces and an indoor weather-backup room. The venue supplies tables, banquet chairs, a dance floor, white linens, tableware, cake and receiving tables, subject to the package terms.
Practical limits are clearly stated. Access to washrooms from the River Room requires stairs, so couples with accessibility needs should discuss the route before booking. Music must be reduced at 11:00 p.m. The venue does not currently provide sound equipment, and the DJ must bring the required system and microphone. Outside catering and outside alcohol are not permitted.
Outside wedding vendors are welcome, but they must coordinate with the Special Events Manager. Wall or ceiling installations require approval, candles must be enclosed in votives, and third-party vendors are responsible for removing their own items.
Current wedding pricing is not explicitly published. Millcroft states that weddings are priced using a minimum food and beverage spend that varies by day of the week, time of day, season and venue size. If the applicable minimum is not reached, the difference is charged.
The official FAQ identifies 13% tax and 18% gratuity as additional costs, along with a SOCAN music-licensing fee and cake cutting unless it is included in the selected package. A non-refundable booking deposit is required, but the current deposit amount is not published.
For weddings booked more than 180 days ahead, the published schedule is a deposit at booking, 50% due 120 days before the wedding, 25% due 60 days before and the final balance due 10 days before, based on the final guest count. Request a written proposal to confirm all current figures and terms.
Couples can call Millcroft Inn & Spa at 519.941.8111 or use the “Contact a Planner” option on the official wedding pages. The venue says dates may be reserved up to three years in advance or longer and recommends booking early for a preferred season and space.
A typical schedule described by the venue begins with a 4:00 p.m. ceremony, followed by cocktails, dinner and dancing until 1:00 a.m. That example is not a guaranteed timeline; confirm access hours, setup time and the required 11:00 p.m. music reduction for the chosen date.
Before signing, ask for the exact food-and-beverage minimum, deposit, cancellation terms and payment schedule attached to the proposed date and room. Confirm the seated layout, weather plan, accessibility route and whether the Erin Room backup meets the expected guest count.
Couples should also review menu and beverage choices, dietary accommodations, cake-cutting charges, SOCAN fees, floral and décor approvals, vendor access, teardown responsibilities and DJ equipment requirements. If guests plan to stay on-site or use the spa, verify room-block availability, rates, booking deadlines and spa access separately.
