Sister,
Think it this way that, if Allah's mercy is in sending you to Canada for visit, you will go even if the whole world tries to stop you. And thats how it happens. I will suggest you to fill out the visa forms without any lies and give the genuine reason of coming back (whatever reason you have). And Insha Allah you will get the visit visa.
For any positive thing to happen in life, the first step is to think positive. That is why Islam also forbid us to be pessimistic in life. Say two rakaats Salaat ul Hajaat, make dua with purity of heart and send your forms, I am sure you will get the visa with Allah's mercy.
