Hey,
I have been a firefighter in Toronto for 6yrs,
Applied to many different departments and was lucky enough to be hired by Toronto.
BEST JOB IN THE WORLD!!!(for me anyways).
The biggest piece of advice I can give ya is DON'T GIVE UP!!! The application process is extremely competitive but if you keep at it you will persevere.
Take as many college programs, weekend courses, or any other courses you think will make you stand out from the other applicants. Trade licences are also great.
Also start some volunteer work in your community ie big brothers, Red cross and so on......this is extremely important.
As stated earlier in the thread, head to your local fire station grab a person that was hired recently and ask a million questions.
Good luck,
Ryan
