Hello,
It depends.. here in Mexico... when you submit all your documents, there is one document that says where do you want to get the answer of your application.. there are 3 options and you should mark only one..
1.to an email account
2.fax
3.your home or physical address
I don't know how the process is in your country...you may want to email the Canadian Embassy at your country after 15 working days... I think that they will tell you that as soon as they have a decision they will contact you...
Keep us updated
Good Luck
Greetings from Mexico
