Is it worth it doing Mercor when you have a job

So I was thinking of getting a full time job for this year and I also received an offer from Mercor. The offer is like 21/hr. I’m wondering whether I should accept it or not.

Reasons for accepting could be that I don’t know when I will get a full time job

Reasons for not accepting are cuz I’m from Canada me so the tax filing and stuff would be more complicated

Plus I’m thinking that if the project doesn’t end in like 3 months or smth and by that time I have found a full time job then I will probably leave the project.

Wondering if it is worth it or not. The only reason I could potentially take it is so that I am still making some income in the meanwhile but my reasons for not taking it would be the hassles that come with having a side hustle. Wondering if I should reject this one and wait till I get another offer? Any thoughts
