I see.. so there is no way I can request for reconsider/ appeal![]()
Reconsiderations are very rarely considered for TRVs and are only done based on what you submitted. You cannot ask for reconsideration and shorten the trip - or add additional evidence. I don't see reconsideration succeeding since the trip you asked for was too long and IRCC likely sees this as demonstrating a lack of ties to their home country. Having said that, if you want to submit a case specific inquiry and try, you can certainly do that. Given global events, it might be several months before you have an answer.
You can appeal but only to the Federal Court. This will take many months and cost you thousands of dollars (you will need to hire a lawyer). I'm not sure on what basis you would be appealing. I think IRCC has strong grounds to say the application was correctly refused based on the request for a six month visit.
Your best option is to reapply from scratch and put together a stronger application.
