Although it's quite unusual to find open clusters so far from the plain of the galactic disc, there is one open cluster in Canes -  Upgren 1 .  Phil Harrington in "Touring the Universe Through Binoculars" directs the attention to a bright grouping of ten or so stars found five degrees southwest of alpha.  At a distance of only 380 light years, Upgren 1 is one of the most ancient clusters known.  Over the last 3 billion years, Upgren 1's retinue of stars has slowly dwindled to its present state - the rest being cast off throughout the years.  Upgren 1 was first identified by Rubin and Upgren in 1965.
