AOR received how to apply for bridging Visa please help

[Joey10]

Hi ,

My current visa is expiring within the next month .I'm in Canada. I have AOR , medicals passed etc.

I need to apply for a bridging visa to carry me over I understand it takes 3months to grant,
my question is how do I actually apply for this bridging visa ?
Do I get notification when CIC receives my application?
How do I know I'm on implied status ?

Thanks
