Program criteria, roles and responsibilities

Doors Open Ontario is a heritage and cultural tourism program coordinated in partnership between the Ontario Heritage Trust and a network of provincewide community organizing partners. Designed to create free access to, and awareness and excitement about, Ontario’s heritage sites, hosting Doors Open Ontario in your community provides residents and visitors alike with a unique opportunity to explore and enjoy the sometimes hidden and always interesting places and spaces in Ontario cities, towns and villages. These events celebrate your community’s identity, generate volunteerism, build interest in Ontario’s heritage and drive cultural tourism and economic development opportunities.

Events should be held on a single day or over an entire weekend from April to October each year. Participating sites must offer free admission to the public and can include museums, places of worship, public, cultural or institutional buildings, private businesses, commercial and industrial buildings, trails and natural areas — and more.

The following criteria must be met for a community to register for an event in the Doors Open Ontario program:

formation of an organizing committee — the committee should consist of a range of community partners, including (but not limited to) the heritage sector, cultural sector, tourism sector, municipal sector, corporate sector and community volunteers
registration for the upcoming season and payment of the registration fee
appointment of one lead contact by the local Doors Open organizing committee to co-ordinate, manage and act as liaison between the Ontario Heritage Trust and the participating community/community cluster
selection of a single-day or two-day date(s) for your Doors Open event, to be held between April and October each year
- each local committee determines the date(s) of its Doors Open event (you may wish to check the event list to see what other communities have registered for a specific date or weekend)
- sites should generally be open from 10 a.m. to 4 p.m. each day, if possible

choice of a minimum of 10 sites to be open for your event
- if 10 sites are not possible, please contact the Ontario Heritage Trust for options and ideas/suggestions

ensure that participating sites must be of historical, architectural, natural or cultural significance:
- visitors to a Doors Open event must receive information about the historical, cultural, natural or architectural significance of all participating Doors Open Ontario sites

admission to each participating site must be free to the public; sites that are normally open should consider opening an additional part of the property or arranging a special event or activity such as a guided tour, walking tour or other unique interpretation
the support of Doors Open Ontario and the Ontario Heritage Trust must be acknowledged in all promotional and publicity materials produced for the local event through use of the Doors Open Ontario logo

What is the role of the community organizer?

Each community must form a Doors Open organizing committee. Specific people should be charged with the tasks of identifying properties, developing interpretive/educational programming, marketing/promotion, event management and volunteer recruitment. The committee must designate one lead contact — the community organizer — to represent them to the Ontario Heritage Trust.

The community organizer is responsible for:

selecting participating sites for the local event
determining local volunteer needs and soliciting volunteers to staff sites on the day(s) of the event (the Trust also collects volunteer interest forms throughout the year and forwards them along to community organizers)
any specific local promotion of the event over and above the media support that the Trust provides (see section below on the Trust’s role), such as local print brochures, small local ad buys, etc.
verifying that each participating site holds adequate liability insurance coverage to participate in a public event as well as meets health and safety minimum standards
tracking visitation at sites on the day(s) of the event

The organizing committee assumes responsibility for all community event-related expenses — although costs may be shared between partners and sites. Expenses might be incurred for items such as brochures and maps listing all sites, interpretive materials, local launch events, volunteer/staffing, cleaning, local marketing and promotion, and the rental of portable washrooms or access barriers. The organizing committee may solicit local sponsors for the local event and such arrangements do not conflict with any provincewide sponsorship for the program.

What is the role of the Ontario Heritage Trust?

The Ontario Heritage Trust co-ordinates the provincewide program as well as the main advertising campaign for all Doors Open Ontario events. It works with corporate sponsors, heritage and tourism groups, the media (print, digital, television and radio) and other funding organizations to provide participating Doors Open Ontario communities with the following:

overall program co-ordination and administration
event planning support to community organizers
access to the Doors Open Ontario website, which is the most important tool to promote your event and the provincewide program (our website receives hundreds of thousands of annual web visits)
provincewide promotion, media relations and branding via paid media campaigns to drive visitation to the Doors Open Ontario website
French translation of community event information for the Doors Open Ontario website and any other provincial marketing materials
community resource materials, including tip sheets on topics such as recruiting and managing volunteers, securing sponsorship and funding, developing a promotion and publicity plan, and managing health, safety and security issues — as well as templates for property interpretation materials, media releases, visitor surveys and site organizer’s evaluation forms
colourful bilingual Doors Open Ontario property identification signs for each participating site — at no additional cost to organizers
