There are always opportunities to get out, but it seems cold lake is a minimum 10 years before you are even considered for a posting. At the 10 year mark you should be at least a MCpl and a SME in your field. At that point you can be posted anywhere as either a tech, instructor, CFLRS, recruiting, etc. Pte- Cpl you are pretty much stuck, those ranks see the worst attrition rate.
I don’t know the official language profile for Bagotville, but the anglos I know that went learned French anyway. Most people that leave Cold Lake are tired of the fighter (CF-18) world. F-35 could change that.
