Thanks for replying!!
I did this course, it was very interesting. They trained us in a swimming pool with lifejackets and fully clothed, in a camp in case we have to survive without food and water, we learned CPR and first aid, that was the most important part of this course.
I think you are right, I'll start to apply to airlines before moving back to Canada, I know it's not easy to get a job in the industry, but I like to hear how it is from people that's already in there.
