Lost all My Keys HELP!!

Ok total bone headedness here...I have lost both sets of keys for my 2006 Montana SV6. I live in Ontario Canada...What do I do and how much (approx) is my stupidity going to cost me...Need to move the "crap can" by tomorrow at 5:30pm

Go to a gm dealer, give them your vin and they can cut keys for you. Not sure on cost of key.
