(Canada) Is it worth doing CPA ?

I am a 4th year accounting student working for CRA (non accounting role). I am not too sure if I want to do my masters/pep and then go for CPA because the salaries I am looking at are not really attractive. If I stay at CRA my starting salary will be around 70K however if I go to a big 4/ mid size the starting salary is around 55-60K and the work life balance is not the best.
