I have organized events as well in the past. In the first meetings, there are always critics. After a while, they go away. They are not up to the challenge. It requires them to give too much of themselves.
Will volunteers play a major role in these celebrations? Of course, you cannot put on major events like this and not ask Canadians to become interested and involved. Personally, I feel that the people who volunteer a lot will ensure that the celebrations are even more impressive. That goes without saying.
