Don't assume your Canadian ScotiaBank ATM card will work there. Ours didn't in Cabo San Lucas (thankfully just cruising through so getting MXP was entirely optional) and much more often than not in Lima and Cusco, Peru (one minor branch's ATM in Miraflores) did, all others didn't.
To be on the safe side, get an ATM card with your name embossed on it (required for manual withdrawals via teller).
