This must be a common shrub; I just don't know what it is, but there was plenty of it on my walk along the seawall in Yaletown. The shrub was about 60cm to one meter, if I remember correctly. Leaves are opposite. The flowers are very small, maybe 5mm. Fruits so far are the same size, with sepals at the ends that appear to be a continuation of the outside skin of the fruit. Pretty cute.
