Help with specific domain and email adresses.

Hi! 

I'm in the process of making my business a new website. I love the ease with which Squarespace allows me to do so. However, we technically already have a website. We're not using it ATM because it hasn't been updated for ages. I found a way on the cpanel to make the url redirect to our Facebook page.

The company that currently hosts it isn't giving us a good enough service. We have troubles with our e-mail adresses all the time. 

So, here is my question : Does Squarespace support adresses that end with .qc.ca ? It seems .ca does work, but I'm not sure for the .qc.ca
How would I go about doing that? We're a small business and we have no on-board webmaster / IT.

Also, is there any email hosting service you'd recommend? Thanks in advance
