Want to apply for a Canadian tourist visa, unmarried, no assets.

As long as there is enough deposit, and now the Canadian tourist visa does not require your deposit period. So you can borrow money from your family and deposit it in the bank. Then, let the bank issue a deposit certificate, and then get the usual bank flow. And your school should also issue a certificate to prove that you are an in-service teacher, but you just want to go to Canada for about a month in the summer vacation. In addition, when applying for a visa, you will encounter a problem when filling out the form, that is, who to visit when you go to Canada. Just say that you will visit your friends (of course, if you have other female friends there), but don't mention your boyfriend, otherwise you will probably be rejected, because the visa officer will suspect that you will stay there. Moreover, the form requires you to write "Take care of yourself" (even if your boyfriend supports your expenses there) if the expenses are paid by yourself or others after you arrive in Canada.
