I dunno, would make no sense to provide housing for some players but not all. Like, what really would be the difference in a player's minor league contract status? All of them are under contract to the minor league team they play for, and by extension the Jays.
Maybe it's the type of contracts they are signed to that matter. Like, in the upper minors there's gonna be a lot of guys that are on the 40 man roster that are just in AAA or AA, so maybe their housing situation would be different than those that are strictly on minor league deals.
