Look up the population size for both cities in the current almanac or at each city's official website. This will allow you to see which of the two is larger.
Look up the average precipitation for both cities in the current almanac or online at each city's official website. This should give you a reasonable idea of how much snow and rain each city experiences annually.
Look up the average temperatures for each season in each city in the almanac or call your local travel agent and ask what months are most popular among tourists. This will give you an idea about each city's climate.
Look up the crime rate statistics for each city. Canada, on average, has a much lower crime rate than the United States, but knowing the crime rates for each city you are considering can go a long way to creating an accurate comparison.
Compare the geographic location of each city. If one is located in Quebec, expect that the language most commonly spoken there will be French. This can be either a good thing or a bad thing in comparison with the other city, depending upon your preferences and language skills.
