Prcompelling evidence as to why exactly you want to visit Canada.If it is a wedding, include a wedding invitation in your uploaded documents. If it is a funeral, include an obituary. Explain who you are and your relationship with the people you are visiting.If you are attending a conference, pra copy of the invitation or if you are not invited, a copy of the program.The most important factor is for you to show that your ties to your homeland is more important than your ties to Canada. That way you are telling CIC that you will return home because that is your home base, where you work and where most of your family is.The narrative you create is all about you creating a picture that while you want to visit Canada, it is only for a short while because you cannot be away from home indefinitely.CIC needs to believe that you will actually return home and won't try to melt into the background in Canada.
