One of the things to watch out for is subconscious bias. For many Europeans it's hard to intuitively understand just how big and empty the country is once you get away from the population centers. Canada has low population density to start with and 90% of all Canadians live within 100 miles of the US border. Once you are north of that, it gets real empty real fast.
Simple example: In Germany you think about "where is the next gas station" once your needle is mostly down or the light turns on. In rural Canada you should think about this directly after you have filled up! Same goes for food & lodging.
You will also have large areas without cell phone reception or internet connection. Make sure you have an offline mapping program! If something goes sideways, you can't just call 911.
Depending on where you are going: you can certainly get snow and difficult road conditions in November. Wildlife is less of a problem. There are bear attacks in BC but they are quite rare.
