First of all in BC you'll not be able to get ANY type of new license because ICBC has suspended all road tests until further notice. There may or may not be a backlog after tests resume because you just call in to book an appointment.
Secondly you'll need to take lessons from a driving school because you're getting a commercial license and those schools are also closed until further notice.
Thirdly, U/L has suspended new hires for the time being. I'm not sure if transferring your Uber status from Totonto to Vancouver is considered a new hire here though.
However if you have an Ontario equivalent (eg. class B,C,E or F) of the BC class 1,2, or 4 then you can simply transfer to the equivalent class here in BC at any ICBC office without having to redo any tests. Any of the above classes are more than enough for U/L. I have a class 2 myself which is a class B in Ontario.
Hope that helps.
