Self-employed - 'Letter from Current Employer' requirement for Work Permit

[Nick123]

Hi,

I am currently Self-employed and have been since 2011. I have been offered a job in Ontario as part of a funded exchange programme between the Canadian and UK forestry industries. I am subsequently applying for a Work Permit to take up this job offer. However, When it comes to the 'Letter from Current Employer' and 'Employment Reference Letter' parts of the required Supporting Documents I am wondering what I need to provide.

- I understand that the 'Letter from Current Employer' is to inform my 'financial profile' so will a letter from my accountant or past tax returns suffice?

- As far as the 'Employment Reference Letter' is concerned, shall I provide a reference letter from my last employer (pre-2011) or shall I provide a reference letter from a forestry company for whom I have provided services as a self-employed contractor?

I hope that I have made my query clear enough.

Thanks
Nick
