Guys, you seriously think that they reject people only because of money? Of course, if you show CAD$1000 for 6 months trip - the will. But if you show 35K as DavidSd mentioned here, the reason they rejected for sure is not just money.
I got my TRV visa last year to visit my BF (!!) and I have shown something like $4000 or $5000 on my account, that s it. And apart from that I had an refusal from Canada before. So from the side it could look like i never would be able to get a visa. But I prepared my file case so carefully and neat, with all the documents that can prove my intentions, that I was almost 100% sure that they will approve my application. And they did.
I strongly believe, that if the person got rejected, in 99% that means that he/she failed to present all the necessary documents/the information was not clear/there were misrepresentation and so on. And only 1% it can be a human error from the embassy side.
Pay some attention to your application's file and you will get the visa. That s it.
