Getting Married after getting the working visa [French]

[lw09sv]

Dear sir,

I am French planning on applying for the working visa in Canada. Also, I am planning on getting married with Thai girlfriend in Thailand after getting the working visa.

1. After getting the working visa of Canada, can my wife (after getting married in Thailand) immediately ask for the spouse visa for following me in Thailand? If so, I would like to know whether I do need to go to Canada first or not? Or I do have to go back to France for adding my wife to the application again?
2. Its possible to ask for the Canada working visa in Thailand? or Singapore?

Thank you very much in advance for your consideration. I am looking forward to hearing from you soon.

King regards,
Alexis L
