Many people in your situation continue to pursue both at this point - although I guess you'll have to see if your NOA2 for the I130 indicates that it is being forwarded to NVC or retained. If it is being retained and you do want to pursue the CR1 you will have to file the I824.
If your sole goal is to get your spouse to the U.S. as fast as possilble, K3 is still your best bet. Depending on if your interview will be in Vancouver or Montreal, the interview for K3 could be 2-4 months from now. After entering on K3 the average wait time for work authorization is about 3 months.
For the I130, the NVC processing may take 2 months, or much more (you never know). Then waiting time for Montreal for interview seems to be about 4 months. So that's looking at about 6 months from now if your I130 petition is actually forwarded to NVC immediately.
Hope this helps!

Okay, I almost couldn't believe this , but after my I-130 got approved
last night, I just rec'd an email that our I-129F has been approved today....!!!
WOW.
Soo should I go for the CR1 visa, and abandon the K3?
Are there any pros and cons to both?
Also, Do I have to send them a notice to abandon the K3?
Please advise with thanks!
