Veveritza,
Welcome to AvCanada! This topic has been discussed adnauseum (many times before). I would recommend the search function and then post follow up questions.
Here is some information that will point you in the right direction:
Transport Canada Helicopter Pilot Licensing:
http://www.tc.gc.ca/eng/civilaviation/r ... 1-1086.htm
Specifically para 9:
(9) Credits for Foreign Applicants
Provided that the applicant has met the flight time requirements specified in subsection (4):
(amended 2005/06/01; previous version)
(a) the holder of a Commercial or higher type pilot licence in the helicopter category issued by a Contracting State is considered to have met the ground school instruction requirement specified in subparagraph (3)(a)(i) and the experience requirements specified in subsection (4); or
(amended 2005/12/01;
I cannot comment weather or not TC (Transport Canada) will recognise your South African qualifications, you will need to contact them.
Once you have the licence requirements out of the way you will need to address the issue of "The legal right to work in Canada". It is not as easy as showing up and saying "hey would you hire me". The process is long and expensive. If you are just coming to work for a short while you can apply for a temporary work permit. See immigration Canada's web site
http://www.cic.gc.ca/english/work/index.asp
Once those two boxes are checked you can then begin the job search in Canada. To be honest with you there is an overabundance of Canadian pilots who are either unemployed or underemployed. I would caution you that the Canadian industry can be very difficult to get into, difficult but not impossible.
Best of luck!
*Mods perhaps a sticky " So you want to work in Canada eh?" Might be in order.
