Northern,
You hsve a few options. One is Amsterdam to joberg as 500grains said also there is Emerites- Toronto to Dubai to joberg and then to Harare. Make sure you have your temp export permit from Canada and dutch consent for Amsterdam police. If you go by Dubai you will need to have Emerites contact the Dubai police to get preapproval. In april when I went to SA they wanted to see my Temp export permit at the SAPS office.
