Chinese Visa for Canadian

Hello, I am a Canadian Citizen who will be traveling to Thailand on January 14th. I am only in Bangkok however until the 17th. I need to get a Chinese visa to get back into China, as I have just started working here (my working visa is in progress) but my one entry tourist visa that I am currently on will expire when I leave the country and I will need another to get back in. Is it possible to get a Chinese visa in this short of a time?

Thank you
