UK Visitor Visa

Hi,

I am planning to apply for a UK visa. Few questions:

(a) Can I apply it online or do I have to fill paperwork?
(b) If I can apply it online, is it through the WorldBridge website?
(c) I also see that they give visa appointments. Is there a fee for booking an appointment? Can I get one in Toronto? Do we have a Visa Application Centre here? If so, where?
(d) The visa fee should be paid in cash at the time of our appointment, correct?
(e) Do we have to carry a copy of our online-filed visa papers to our appointment?
(f) Finally, where do we get our biometrics done? Same location, same day?

Please feel free to add your tips if I have left out anything important.

Thanks!

what visa would you be applying for? If you're a Canadian citizen, you don't need to apply for a visitor visa before hand. You just go.

Has anyone applied as a General Visitor for longer than 6 months? I am traveling with my sister when she attends law school and have enough savings and other income from rental properties to support myself without working. Or, would I be better off applying for an Ancestory Visa since my grandfather was born in England? But, if I do this, do I have to commit to working fulltime? THANKS so much for any responses!!
