I am now in canada with my visit canads that will be expired in one month. I have renewed my passport and want to know if I could apply for new visa inside the Canada?
No, you cannot apply for a new TRV from within Canada. You can only do this outside of Canada.
If you want to stay in Canada longer beyond the length of time CBSA gave you when you entered Canada (I assume this was six months), then you can apply for an extension to your visit from within Canada.
However applying for a new TRV is not possible in Canada. Only possible outside of Canada.
