These are extremely expensive programs that the Swedes have historically been willing to pay to maintain as much neutrality as possible in their defence procurement system. A Saab Gripen has almost the same flyway cost as an F-35 because of manufacturing scale differences (maintenance is far cheaper, though) and the Gripen is far less capable (it is one of the best western fighters if a full blown war happens and your bases are all destroyed, though). Sweden had unique defence requirements due to this that wasn't being met by others.

Sweden was forced to take their defence seriously due to their geography and political will. Canada has had an easy ride and when the going got expensive, we cancelled our domestic programs (most famously the arrow, but also a lot of other stuff).
