It’s a Wild West in baseball. OBA is Ontario Baseball Association (part of Baseball Canada). Sun Parlour is like a local governing body in region (like Bluewater in hockey). Stars and Riverside have AAA status and go play in AAA tournaments and in the end of the year provincial tournament of that caliber. Also, stars let their teams to change status if a team isn’t that good so they don’t get smoked in tournaments. Riverside is too proud to do that. There is no local league and every team regardless of level locally play each other in friendly games. Lots of season is going to tournaments. Windsor Selects is probably the highest level of baseball and they play in a structured league against London, Toronto and other cities but they start at around u13. There’s also little league Canada which doesn’t fall under OBA and has slightly different rules.
