Can I extend my visitor visa while staying in Canada?

Yes, you can apply to extend your stay as a visitor before your current authorized period expires. You need to submit a visitor extension application online, providing proof of funds, valid passport, and travel history. Extensions are usually granted if you demonstrate a genuine purpose to stay temporarily and sufficient financial support. Overstaying without approval can affect future visa applications. The typical extension period is up to six months, and processing times can vary, so apply well in advance.
