They are often not as different as it's painted. In Europe, there are many different countries. One of the projects of European integration and cohesion has been standardizing across the continent from very high-income places like Switzerland—which isn't even in the European Union, but typically follows EU standards—to low-income places like Romania, where my mother lives. You have vast differences in climate, from southern Italy to the top of Norway, yet they have found a lot of ways to integrate within themselves.
There are many places in Europe that have climates that are like those in Canada. You have similar languages. There are more similarities than differences. Fire burns the same. Structures and materials have the same properties. I think there are more similarities than is often portrayed in the construction industry in North America.
