Departure tax deferred collateral

[safgas]

I am an individual, (not a business) with a large departure tax bill. I am working on deferring it while living in the US. My most basic question: Does anyone know which Canadian bank will write a letter of security for CRA and the approximate cost. Ideally, we would like to work with a Canadian Bank that also operates a brokerage in the US. I'm being herded to Private Wealth Management at all the banks approached so far, that generally requires $5M to invest. TD is the best candidate, tho hitting snags here, too.

Typically, TD Canada Trust, RBC, BMO, Scotiabank, and CIBC all have the technical capabilities to do this, but only if you meet their requirements.
