Fai,
Please do all of us a favor; especially the ones you PM'd...Read the STICKY about employment in Canada.
And if you are trying to go back to India after you are done with your training, remember you are one of several thousand 250 hour wonders competing for a limited number of jobs. So please, read the STICKY, and take it from there. If you want to know about employment with Harv Air as a CFI, I suggest you not only email them but call them and ask them and stop posting and PMing others like myself with the same question!!!
