Wild shrub identification

I travel the trails along the Trans Canada Bike Trail and have come across the this shrub and it doesn't show as well in the photo's but has a purple color hue to it. I am wondering what the shrub is and are the berries safe to pick.

 

Looks like chokecherry (Prunus virginiana) to me, which is edible to my knowledge.

 

Thanks for your expertise and quick response. Have a good one!
