Come - dont leave.. But if you want to do it legally you'll need to file some paperwork and stuff. Best paperwork depends on your situation. Single (want to get married), financially well-off, pentioner, bring your own job, willingness to work etc.
You can take a risk and say the airBnB is your friend. But I don't suggest it. Pre covid you only needed to show a booking for a few days. You could create the booking, print the confirmation, cancel booking. But I don't know how things are now. It's kinda of a soft requirement in that almost anything will do. But AirBnb, because its illegal.
Don't pack them in your checked baggage. It's been my experience that airlines sometimes ask for required documents at check-in. Also Immigration Officer may/will ask for necessary documents when reviewing your passport/visa, etc. In the Thailand airports you get your baggage after immigration.
Point is - don't be a dick! Keep the paperwork handy. If not for your sake, for the sake of the poor schmucks standing in line behind you.
Every embassy has the option to give you a visa or not. Every immigration officer has the option to allow you in - or not. In both cases the things they may or may not ask for will differ by who is asking.
From what I remember Manila is quite strict about their requirements. I can show up with some of their requirements and a copy of this post and request a visa, I am sure they will decline my request.
Australia has a few (5 I think) Thai embassies. Each with different requirements. What one embassy will find acceptable and grant me a visa, another embassy may not.
You could skip the visa stuff entirely. You could show up at the airport and not be asked for anything because the airline is in a hurry. Then continue on to immigration and the immigration officer may not ask for anything and grant you entry. That doesn't mean that will happen for always for everybody.
Couple of points to consider.
A) This is a foreign country (to anybody seeking tourist visa), it is best to act like you are a guest.
B) Everybody can have different experiences depending on several factors (Immigration officer mood, the asshole in front of you, the Embassies policy makers motivations, embassy employee's mood, etc etc). Because you have one experience does not mean you are guaranteed the same experience the next time.
C) The rules and guidelines - help assure you are not the asshole mentioned in 'B'.
Also noteworthy, I have always had success with bus tickets for onward travel requirements. may not be applicable currently - but 'onward travel' doesn't mean 'transportation home'
Flying would probably be best. When you arrive you will likely need a visa also.. I would recommend packing a bag, tooth brush clean underwear stuff like that. You can buy those here if needed.
I think the only way this makes sense is if you plan to use the internet at home, while you are away from home. Like maybe run a server or something (Your IP will change, not a great idea).
If you will only use internet where you are, and you always have your phone with you, you can use the wifi on your phone. I primarily use my phones wifi. In many places in Thailand the cellular+wifi is faster than ground cable+wifi.
I really wouldn't worry too much about it. Canada is likely to have identity checks so if someone else uses your details to get a job, the fraud will be discovered. Not likely people will try something like that in Canada. The probability of you and some fraudster applying for same job in the same country are very slim.
However, you will want to get official record, police report or similar. Getting a new passport maybe a good idea.
One issue that may arise, if the fraudster gains employment in the same country as you, then you may have financial troubles, taxes, credit etc.
If you have documentation that you reported your identity things were mishandled (police report, new passport) it maybe useful in the unlikely event you will have to prove your identity information was mishandled.
But ultimately the world is a big place with many people the likelihood you will cross paths with the fraudster is slim.
I came to Thailand because I wanted to leave my home country (USA), I wanted to explore the world a little and Thailand had the best prospect of support myself. I taught for a couple years then started working online. I like Thailand. I am always happy to return to Thailand, people here are great. So now I stay in Thailand and travel the region. Covid has restricted travel, but Thailand is still better than the US.
