So, say I have a SAMD app that we market in the US and Canada. I understand we need ISO 13485 under the MDSAP for Canada. But, the US is optional. Will my registrar allow this? i.e. Can we sell to both countries, but have the registrar audit us with only Canadian regulations? I get that this opens us up for audits by the FDA, but if we are located in Canada, the audit cycle is only once every few years and an FDA inspection of a SAMD company is not that much of a burden. It may be worth the cost savings of having our registrar not include the US in their audit plan... if that is allowed.
