You can get to McMahon via the CTrain (about a five minute walk from the Banff Trail station; take the Tuscany train); a door will be open for people to walk in (between the clubhouse on the south side and the SE entrance, just go down the hill/stairs). Team store will also be open. Schedule can be found here:
