I like you don’t have winter storage or summer for that matter being overseas every 2nd month. The wife’s car goes in our single garage so for the Corvette and Hummer I rent a nearby 2 car garage. I’ve had it for years now. It’s not cheap but likely less than a storage place and I can come and go as I please. Have you considered that? Don’t know what it’s like in YYC but in YEG they are hard to find this late in the year. Kijiji seems to be the best bet if you are considering it. I would give you one side of mine but the H1 is in the way.
Maybe someone there in Calgary has an open spot for you.
Thomigun: this may be a bit late, but David has a great facility, and he did charge about $1100 p/ann, where by you could move you cars in and out depending on your requirements. He stores about 300+ cars of various types, worth a phone call.
