Sorry I was not more detailed.
When I signed I was naively not aware that it would take 4-6 weeks to get my medical form completed as they had not forwarded this document on. It was a bit stupid of me not to know about this, but my GP is adamant he will not complete the form unless everything is completed - X-rays etc - and this was all estimated as taking this time. So the chances of obtaining a Z visa in time before my departure are now very slim.
I'm aware that all employers require this form, but another in the same province has raised the possibility that I could cross out the X-ray etc sections so my doctor would not have to complete these, and therefore make the medical a much faster process. I'm waiting to hear from my contracted University as to whether anything can be done, but if they cannot help, I would prefer to withdraw than enter on an F-visa (a possible solution they may offer).
Do you know of anyone who has been in a similar situation?
