Need Help to remove duplicate title and meta desc

[kartika.ismoyo]

my duplicate title and meta description increasing each google update its "HTML improvement"

i have use canonical link rel and redirect 301 as a solution but it still increasing dramaticaly.

here an example of my duplicate link:
1. mydomain.com/detail-listing-193
2. mydomain.com/detail-listing-193.html
3. mydomain.com/detail-listing-193/some_param

all that link are redirected on .htaccess to : mydomain.com/listingdetail.html?propid=193
