I'm glad to hear that you will be commemorating the arrival of the Irish in your region. That's exactly the kind of thing we want to see.
There are two elements to consider here. The first is what I would call content. You mentioned important elements, such as the arrival of the Irish, the colonization of western Canada by francophones, the role that francophones and anglophones have played together and the history of linguistic accommodation in Canada. People tend to see the negative aspects of that history, but there are positive aspects too. Both aspects should be addressed in terms of the content.
There is also the element of presentation. We have already developed a manual for organizers of major sporting events. It explains how to organize an event keeping in mind respect for both official languages. We need to plan and collaborate with communities and in many cases with schools. We adapted the manual for organizers of community celebrations that will take place in 2017.
By planning and investing time and effort, it is possible to ensure that francophones and anglophones travelling across the country will be able to fully participate in these celebrations that give both official languages their rightful place.
For example, I would like to talk about what was done in Prince George for the Canada Games. A fairly remote community in the middle of British Columbia made a major effort to ensure that the games provided a welcoming atmosphere for francophone and anglophone athletes and their families. There were signs, manuals, announcements and documentation in both official languages. It was a huge success. Their best practices can be used by other communities planning celebrations for 2017.
