If the threat model is "the US goes rogue and does crazy stuff", Canada is a prime risk of suffering from such madness, so moving your resources there doesn't really change anything.
Agreed, but I'd argue that there's a big difference between the US making it difficult to access gold reserves stored there and invading/blockading Canada to the point where gold reserves stored there are unusable. The first seems unlikely but possible, while the second seems almost unimaginable, and even if the second does happen, I'd be more concerned about access to food/medicine than access to gold reserves.
