Sponsorship options

Hi,

Hoping some wise people in this forum might be gracious enough to help me answer some questions... (I've called Canada Immigration but they don't seem very helpful)

I am a Canadian living in Ontario and my significant other is Austrian living in Austria.

I'm considering all options for her to come to Ontario so we can be together AND allow her to work.
- We are currently not married
- We do not qualify as "common-law"
- We DO qualify as "federal skilled workers"

It seems that we have 4 options:

A) Apply for Temporary Work Permit
- very hard for her to obtain a job offer letter

B) Apply for Permanent Residence as a Federal Skilled Worker
- processing times are on average > 9 months (Vienna 50%)
and up to > 3years

C) Apply for Permanent Residence by Spousal Sponsorship
- would require us to get married
- processing times are on average 3 months (Vienna 50%) and
up to 6 months
(** PLEASE CORRECT ME IF I AM WRONG ABOUT THIS DURATION **)

Now my questions:

1) Are there any errors/omissions in the above options?

2) Regarding Option C:
i) We can apply while she is outside of Canada
If we do this, do we have to wait for a decision to be rendered
before she visits me?
ii) She visits me and then we apply while she is living with me
If we do this, everything i've read tells me that she can continue
to stay in Canada (though not work) until a decision has been rendered.
I've also read "in between the lines", that if the process takes a long
time, they may grant her a work permit before coming to a decision.
Is this true?

Are there any disadvantages of doing (i) rather than (ii)?
If so, what?
Does (ii) take longer to process than (i)?
If so, how much longer on average?

3) Can we apply for all or any combination of (A), (B), and (C) concurrently?
Is this a waste of time or dangerous?

Thank you for any generous advice you might offer,
Ignac
