Stew answered the question for the status quo of the law.

Some of the people posting to the question seem to be unaware the laws on storage are supposed to change sometime in the current Trudeau mandate, assuming they stay in power long enough. It was mentioned in the mandate letter to the minister (Blair I think) and discussed elsewhere on these forums. I just think it could be a waste of money to put out hundreds of dollars on the hardware and installation and then to redo it. The details matter and they have not been seen for any future storage laws.
