Speakinfrankin,
I myself am quite un- informed and currently researching exactly what you have inquired about. I cannot seem to find a "list" per se, however, a small gem I recently learned, (to supersede a long held disappointment towards Canada) was:

Foreign nationals who have been convicted of two or more summary offences either in or outside Canada will be deemed rehabilitated if

* five years have passed since the sentences were served or were to be served; and
* they have not been convicted of any other offences at the time of their examination.

Just thought I'd share a bit of the knowledge with you. It's always going to be difficult for felons to do damn near anything, but perhaps not impossible if we look into some of the details.
