Toronto is such a theater town that even tiny tots (and the rest of the family) get their own performance center. For more than 50 years, the always-enjoyable YPT has mounted whimsical productions such as Jacob Two-Two Meets the Hooded Fang (by the late, great Mordecai Richler) and children’s classics like Mary Poppins. This theater company is particularly committed to diversity in its programming and in its artists.
