I would assume they would ship anywhere in Ontario, not sure what the fee would be.
I work for an agency (Noble Estates) and our mix cases aren't "live" yet. You would have to look around to see what others are offering. They will be pre made cases. So you can't pick and choose each bottle. (LCBO rule)
But if you were to know what I would want, could you pre make a case that fit that need??
