Best Pork Bun and Custard Tart in Markham/Thornhill or Toronto Area?

[TeacherFoodie]

I skipped Golden Gate Bakery in Chinatown, San Francisco to save stomach room for other things and now am wondering where I should go locally to get a great pork bun and Custard Tart?

It's been awhile but we always liked Lucullus (we get our fix at dim sum...not the same but close enough for us).
