Unable to download some country apps

Actually i recently shifted from india to canada , but i am using the same id which i had in india. I don’t know why ? But i am unable to download some common apps here like kjiji and pizza pizza. They are not available on my appstore but if i try to find them out online it shows a warning that this app is not available in your region.

please fix this problem for me .

i will be very thankful to you.
