Who am I?

We recently moved into our new place with a garden, this tree has fascinated me whatching it this past month. I don't know what it is, I was thinking a plum tree cause they rule the Lower Mainland BC in the springtime. The trunk had a reddish tinge and I was thinking plum, and was excited. Finally the leaves took hold and I thot no blooms for you, until I started paying attention and bees were all over it. Upon closer inspection the flowers are under the leaves and this is what I found. Would like to know what kind it is, anyone? Thankyou
