Question regarding marriage/type-o immigration visa for Self-Employed individuals:

Hi there, I'm currently on an METV visa on my second entry in Thailand. My wife is Thai, she's currently stuck in Norway (and I'm from Canada, she can't go there and I cannot go to Norway right now). I was not anticipating to stay in Thailand past May this year, but it's looking like plans are changing.

I am looking to apply for the Type-O spousal visa in Thailand, but I have a couple questions for anybody who can shed some light. Does my wife need to be in Thailand to apply for this visa? Secondly, we do not yet have 400k in a Thai bank account. We could make this happen, but from what I've read, the money needs to have been in the account for >2months prior to the application which leaves this one out. This leaves me with the option of proving I make at least 40k/baht per month. As a self-employed individual, how do we go about proving this other than tax/bank statements? Will the Canadian embassy provide such documentation, and would I have to physically appear at the Canadian embassy in Bangkok? (I'm Currently in CM)

Lastly, I still do have the option of returning to Canada, but I would greatly prefer to be here for my wife if she can no longer stay in Norway (she has been layed off from both of her jobs). Any information would be very much appreciated!
