One of the best ways to move assets outside the country is to buy land.
It can't be repatriated.
Any account of a US citizen can be forced to be returned to the US. Many/most countries have rules that prohibit US citizens from opening accounts.
If the powers that be decide to confiscate gold and silver again...do you think you could get into a safe deposit box in Canada??
I'm thinking about the same issues you are. Do you buy land in Canada and then place your gold and silver in a floor safe??
That would be the safest thing to do.
