There is no “marriage visa.” Your boyfriend can sponsor you for permanent residence once you are married.
Do you mean you are extending your study permit? Your study permit entitles you to work part time while school is in session and more hours while school is not in session. There is no longer any separate work permit. You can apply for a post graduate work permit but it seems as though you have already applied for a new study permit. (You need a study permit to take a one year course.) If this is true, you can work full time between May and August and then resume part time work in September.
If this answer is confusing, you should speak to an RCIC or a lawyer or IRCC.
Your study permit application shouldn’t be rejected just because of your brother but they will likely think you more likely to try to stay with your brother already here. You will have to prove you are returning home after your degree.
You need to convince them that you will return, not just that you are willing. A deed to your house, or rental agreement with your landlord, plus proof that you are permanently in school and need to return to finish your degree are a start.
If he’s a UK citizen, he’ll need an eTA to come to Canada regardless of your citizenship.
You can apply for a visa but it’s very likely that the application will be rejected because they will suspect you are going to overstay.
You’d be much better off getting sponsored by your boyfriend. But you can still apply for a visa to see if they’ll approve it.
You should be able to re-enter however you can expect questions about your intentions if you haven’t gotten an extension. (This assumes you have a valid eTA/visa to get to Canada in the first place.)
If you still have a valid visitor visa, you can travel to Canada and enter Canada as a visitor. You should not attempt to enter as a student if that study permit contains incorrect information and you did not apply to correct it.
There is no special visa for this. You need to apply for a visitor visa.
If you want to work in Canada, you need to apply for a work permit, which normally requires a Labour Market Impact Assessment (LMIA) and a job offer from a Canadian employer.
