I want to get a Prunus Serrula because of fantastic bark but can't
find anyone carrying it.

Does anyone know where I could buy/order this in Toronto?

Or does anyone have other recommendations for a tree that has such an
interesting trunk?

Perhaps you mean Prunus serrulata (Kwanzan cherry), most any plant
nursery will be able to accomodate you. What's so fantastic about the
bark, not much different from any cherry tree.
