In Toronto you will not find many....
I am not familiar with any Dominican restaurants here in Toronto at this time although the one posted in the link in post #2 might be considered new if it opened in the last five years.
I went to one in the 401 and Weston road area about five years ago and I don't remember the name. They had recently opened but apparently had a good crowd at night because of the neighborhood (not the greatest). I went for lunch and the food was okay.
When Friendly Dominican Restaurant was open on St.Clair I went quite a few times and enjoyed it. Good live music as well as a very enjoyable crowd.
