Not all these sources are authoritative (for example, the CBC was the only source I could find for some of the numbers).  Also, not all these data sources clearly distinguished between travel-related and non travel-related infections.  Finally, the actual counts can change over time based on the laboratory tests, and for other reasons, so the final numbers are always a little mushy.  But you get the general idea.
