This will be definitely the end of journey for you in Canada and Western countries for sure. This will not affect only you, it will probably affect all your family members (parents/siblings) if they will apply for any temporary residence permit in future whether in Canada or any Western country.
Your frankly don't have a case. Your refugee application will get rejected sooner than others. This is what is happening to international students applying for asylum just to stay in Canada. This is a stupid idea suggested by greedy immigration consultants/lawyers and/or social media people who are after views and comments.

If you love Canada and want to return, it is in your hands. Focus on learning French. You have a good chance to get a regular immigration through Francophone EE.
Pack your stuff and go back home. Don't regret it. This will only be temporary. You are still young, you can work hard and continue learning French. This way you will be able to save some money to apply for a regular immigration stream.
You can come back in maximum 1-2 years through an EE stream.

Sorry for being so direct and straightforward. I don't want you to go through a dead-end road that will have its consequences for the rest of your life.
