Yo! Smart; you're not thinking smartly. I agree with Jurassic; so many factors come in to play when an organization hires. Another two are; your work ethic and your ability to teach because you are an instructor does not mean that you are a great teacher; that will come with the experience. Most school hire internally first unless you have exceptional credentials. The reason is the school gets to know you as an individual better and determine if you are the right fit for them.
Firstly; I personally think you should contact Transport Canada and find out exactly what you need to convert your FAA to TC. Secondly; go and get the Instructor’s Rating done; worry about the job later. If you don’t get the rating you still cannot get hired as a Class 4 Instructor.
Best of luck in your endeavors
