I don’t know your budget but based on my own experiences as a journalist, I can personally vouch for 3 firms, all in Toronto. In the interest of fair disclosure, I use lawyers from these firms as editorial advisors and have great personal affection for all of them. But I can also say without a shadow of a doubt that they’re all first rate lawyers. So, take this with a grain of salt.
