This is a great document that clearly lays out the financing options in the US. I found this in particular interesting. This financing could be completed very quickly:

If securities in an MJDS offering are being sold only to U.S. investors, the issuer will file the prospectus with the SEC and just one provincial securities regulator, typically in its home jurisdiction. Depending on the applicable regulator, the prospectus will often not be reviewed except in unusual cases where there is a problem with the transaction. If the prospectus is selected for review, the issuer must be notified within three business days of filing. The period from filing the preliminary prospectus to filing the final prospectus and becoming clear to complete sales of securities could be as short as a few days or even less. The timetable for a U.S.-only offering under the MJDS may, therefore, be much shorter than the timetable for an offering being sold in both jurisdictions involving Canadian securities regulatory review
