Having the "EUA" stamp may not be a problem for Canadians, but that is not the only impediment to having a test on hand before travelling to SXM!! First, at the current time in Ontario you have to have a reason for having a test done, and it doesn't include tourism. Second, many of the test facilities here, as is the case in many US states, cannot seem to turn out a test result within 72 hours, as is required by SXM. So, the problems may be different, but meeting the test requirement is still problematic.
