I would like to do Post doc in canada or australia or any europe countries. Which Country or Universities are easily to grab the opportunities. I have completed my Ph.Drecently with two SCI Publication.
It's not that difficult to get a post-doc in Europe or USA. It depends on your motivation and passion. I would give you these suggestions.
First, I would suggest you to look for professors in your specific research area and contact them directly with proposition of research collaboration with your unique research idea. I am pretty sure it will give you a good chance of getting post-doc in your intended market. Moreover, try to be specific and clearly articulate your ideas to the professor so that he/she can see your potential.
Second, you can explore different websites specifically focusing on ads related to post-doc or job opportunities in UK/USA etc. For instance, join "Indeed: Job Search" portal for notifications about different opportunities.
