Help: Google Snippet Being Hijacked

So my wordpress website for one of my offline businesses isn't showing up on google anymore for a keyword that it was showing up on the first page for ages. But when I type in the domain on google I get it on the first result https://www.google.ca/webhp?sourcei...&espv=2&ie=UTF-8#q=torontoaluminumrailings.ca However, the snippet info (Title and Description) is not at all what I have set on my wordpress. I am not using any SEO related plugins either. As you can see below the first result, my sub-pages show up fine but my homepage is all messed up. My info should show as follows:

Title: Toronto Aluminum Railings
Description: Providing Toronto and the GTA with quality aluminum railings installation services

Instead it shows (as show in the link above):

Title: PassTody - Pass IT Certification Exams, Get IT Certifications ...

Description: PassTody latest real test questions and answers for all IT certifications.

What do I do? What could be causing this? Is my site compromised somehow?

I see what you mean. Don't know, any security plugins you missing?

That is strange but one must not giveaway that much details in public mate.

What changes you recently made to your site ?

It seems that your website is hacked. I checked your site with googlebot user agent and it's redirecting me to another site called http://www.passtody.com (Their title & description is what you see in your serp).
So there must be some sort of cloaking that's been inserted to your coding so googlebot sees a different site and normal visitors see your site. You should check your .htaccess file and other script files which are modified recently.

Sorry for my english.
