This graph shows the number of .ca web sites by differentiating the route the packets are taking to reach them. The lines are stacked, where an additional line is added over the previous one. The addition of the lines gives the total number of .ca web sites.
Since this data is based on the registered location of AS numbers, it may well be that sometimes the packet goes through some Canadian provider even if it shown as non-Canadian. The inverse is also possible.
