My cousins tell me that Skyview has one of the best dim sum in Toronto. Having only tried a handful of places the few times I have visited Toronto, all I can say is a dim sum at Skyview is similar in many ways to what you get in the bay area but the execution it's just better.
The menu features the same cantonese classics. The least of what we ordered was as good as what we got at ABC or Yank Sing while the best was definitely a cut above.
Try the chicken feet, the various dumpling combinations or the har gaw. It is all good.
