Ok Wings you did good. anyway is not wrong.
if you really have lived and not did just travelling of vacations or shopping you are right. Make sure you remember all dates because if you declare that you have lived you must know them.
Don't stress your self too much, everything is going to be ok. Is too much work for the embassy to verify all your trips around the world, You maybe have lived in China, Brazil for a Month or two days, you know how much time it takes to verify all your trips around the world from the age 18? It needs that the embassy have one office in each Airport, each Customs House all the around a world that gives a personal data and information to simply Canadian Embassy. Your files will be verified only in the General offices of Interpol.
Hope this it will help you a little Wings.
