Thank you my friends,
About the courier there is another experience for me I want to share with you guys!
As I understood, Sydney in Nova Scotia is the end of the world! Now I can understand why Canada forced all applicants to send their applications to Sydney Nova Scotia! The reason is to increase transportation and improve local economic in that area!
Anyway, I used DHL courier to send my package to CIO and as I told you guys, they picked up my package on 30 April and it was Thursday. I could track my package's movement in DHL's online tracking system and it was great until Sunday - May,3rd and my package reached to Toronto with this message: "Arrived at Sort Facility ONTARIO SERVICE AREA - CANADA" at 18:00. It was very fast and it reached Toronto in just in 3 days! And then it left Toronto with this message: "Departed Facility in ONTARIO SERVICE AREA - CANADA" on the same day at 22:13 But after that the story began!
On May,4th there wasn't any report and on May,5th , it reached Nova Scotia with this message: "Arrived at Delivery Facility in NOVA SCOTIA AREA - CANADA" at 9:24Am. OK it was very close to destination and I expected, it could be delivered in the same day but there wasn't anything until 15:58 of May,6th and they added another message to their tracking system and it was: "Scheduled for delivery as agreed"!!! Then after another day waiting, it finally Delivered at 14:27 of May,7th! It means my package reached Toronto within 3 days and transferred from Toronto to Sydney Nova Scotia (it is 1500Km away and it is only a 2 hours flight) in 4 days!
When I checked to find the reason of that strange delivery then I could find an interesting result!
DHL itself isn't active in Nova Scotia and it hand over all packages to another courier "Loomis Express" to deliver them and that was the reason of delay and strange delivery of my package.
I found this topic inside our website:

You can read others experiences on this matter.
If you are going to send your packages to CIO, you can find a better courier that works in Nova Scotia for preventing further delays and strange delivery!!!
