CJBS?? - Maybe the 1st one could be another form of chub that occurs in ON. In the picture the mouth doesn't look quite big enough for a creek chub. I am not real familiar with all the chub species. I think the second picture is a common shiner aka striped shiner. which was probably mixed in with the emerald shiners. It is possible the supplier of the emerald shiners got them from a river or large stream which explains the chub and common shiner in your pond. Neither will spawn in your pond but if the chub is a creek chub it will grow to 10" and eat young perch esp fry to 1" long. If you catch it again use it for cut bait.
