I am working on MS access for couple of years. I want to further enhance my knowledge with VBA.

Any collage or institute in GTA.

Or any helpful website or any books. I will appreciate.

If you have experience in other types of programming, I don't think you will need a training class from a college.
There are many good (free) resources online for any level - beginner or advanced.
Start with the MSDN :
