Your visa was hardly refused for lack of international travel experience.
I guess you were issued something like this (with not the same boxes checked):
The official making the decision was obviously not satisfied that you would leave Canada in time. This would have been an overall assessment, based on all available relevant information. That your travel history was considered does not say how it affected the decision, if at all.
In any case, you need to convince the Canadians that you will not overstay, by providing new information. You will not achieve that by travelling to random countries.
