You are also aware that two of those cities were part of NASL and that one not only won a title but inflicted the worst defeat the Cosmos ever suffered as well? And when those teams came in MLS was largely a bunch of teams doing very bad interest and attendance wise, they instantly strengthened the league (for example the league has a good TV deal with TSN that brings in significant revenue).
Don't care about the NASL or the Cosmos nor any team in Canada. Not my team, not my problem. Fuck em.
