The province updated its public health announcement on December 16.  

The summary from Sport Nova Scotia to us (boldind added) says "

As the regulations relate to sport, effective December 21, sports will be able to practice/train with groups of up to 25 without social distancing. The number of 25 would include all participants in the sporting activity, (coaches, trainers, etc.), as is consistent with all previous regulations. Games, competition, and events are not permitted, so all teams/training groups would be consistent within their own personnel.  

It’s important to note that these new regulations will apply to the entire Province, so games, events and competitions that were previously taking place in some zones of the Province will not be permissible under the new regulations.

These regulations will be in effect until January 11, 2021."
