There are directories focused on websites which have a specific country extension or those which are limited to a particular country. If your website has a .ca extension or you ship your products only in Canada, then you should go for a Country (Canadian) directory submission. Country directory submission is the most recommended service for websites operating for a specific country.

I have done other directory submissions earlier; Can I do a country directory submission now?

Yes, you can as long as your website is country specific. The list of country specific directories are exclusive and do not clash with other directory lists.
