Advice needed on cloud/software solution for home+corporate accounting with some complex specifics.

Please help!

I am looking for an accounting & bookkeeping solution to manage both my personal and corporate books. To my surprise it seems harder than I thought to find an application or cloud based service which can do the following:

• Track my personal and business expenses separately in one
  program

• Sync with my banks to import data

• Separate/organize expenses which are a mix of business and
  personal made with one credit card

• Maintain a double-entry accounting system

• Handle both Canadian and US currency (this one isn’t mandatory, but definitely ideal)

The following are features that I would either like the service to provide or at least be able to link to an application which can handle these:

• Scan receipts and import data from smartphones or desktop scanners
• Import email receipts via email forward or ideally through a bulk import of .eml files
• Help track business and personal Canadian tax issues including GST collections from clients, etc.
