Skate Canada's website now lists Corey Circelli as the 2nd man for JGP Poland (he and McIsaac are assigned to the first & last JGPs in dance) and Eric Liu is listed for his 2nd at JGP #7 in Italy.
Canada was the 4th highest placing country at 2019 Junior Worlds and have picked up an extra men's spot for each of the first five JGPS due to Italy not using theirs (still TBD about the final 2 JGPs).
Challenger men's assignments listed on Skate Canada's website:
Nicolas Nadeau (U.S. Classic)
Nam Nguyen (Nebelhorn)
TBD: Finlandia Trophy and Warsaw Cup.
Messing and Nguyen are scheduled to make their season debuts tomorrow evening as both are listed in the SP starting order for the North York Summer Skate tomorrow, along with Roman Sadovsky, Conrad Orzel and Bennet Toman.
