I will always give a nod to events staged by the government, such as the civic music and bands at Mel Lastman Square or the remarkably under-publicized "fun and free activities" at Queen's Park.
History buffs might pay regular admission to experience "Dominion Day" at Black Creek Pioneer Village.
Perhaps the biggest and most exuberant party will be the Pride Parade on Sunday.
My article has convenient links to those events and the others that are not mentioned here. I also promote my article in my Xanga blog ("2012 Canada Day Events in Toronto").
Writing Tips based on Canada Day 2012 in Toronto
If you need a niche, build a portfolio of articles about annual local events.
Be sure to take a unique approach. One sure-fire winner is to adapt a "review" style, much as one would review a restaurant or movie. Your first-person account, illustrated with your own photographs, will be indisputably personalized.
My approach is to give people options for planning to attend special events, rather than reviewing them afterwards. In my view, that makes it difficult to write with the same authority; even if I had been there the previous year.
That's the approach I've taken in writing about upcoming Canada Day events in Toronto for July 1, 2012.
