As you can see, I circled the OR as in you need one of the two. But from what I know, you can do the 65k baht per month after your initial year. The pros will chime in soon enough.
As a fellow Canadian, who travels to Thailand frequently, I’d suggest you have the onward ticket ready when checking in. I’m assuming you’re using Air Canada and they WILL ask you about it. I’ve also had Qutar ask about it as well.
If your visas don’t arrive in time, you’ll enter on a 30 day visa exempt stamp. When you do receive your visas, you’ll have to leave the country and re-enter to activate the visas.
good for you! Nobody cares until someone does and you have issues trying to get into a country. Imagine, you go away on a vacation, everything paid. You get to the immigration officer and they deny you entry. All because you wanted to overstay in another country. I will never understand why people let themselves get into these situations with overstays. It’s not hard to follow rules. I guess it is difficult for some.
