Montreal border

After reading a really nice post about geo-marked bike accidents (Mapping Bike Accidents in R), I wanted to reuse the map for something else. Unfortunately, the shapefile used to create it does not give the entire border, but an aggregation of borough instead.

So, after a couple hour looking on the web for a simpler SHP file, I gave up and finally decided to create it myself. To do so, I used the SHP file given on the Mapping Bike Accidents post.
