With the hopes of better understanding which policy environments encourage and support innovation, new research from the C.D. Howe Institute, a Canadian public policy thinktank, examines which sectors and provinces drive Canadian patent intensity. Using a new database on patent applications in Canada, the authors find that inventors from Ontario and Alberta, in addition to inventors in the utilities, construction, and computers and electronics sectors produce a disproportionally large share of Canada’s patents, while inventors from Atlantic Canada or in the pharmaceuticals and medical equipment sectors are not producing a large share of patents.
