Does a Canadian patent application protect my invention around the world?

Patents and patent applications are territorially limited – your Canadian patent application does not protect you outside the borders of Canada.  A Canadian patent application can be used as a priority basis for filing in other jurisdictions in certain cases, and there are a number of different international filing strategies which can be employed to streamline the process if broad-based geographic protection is desired – including proceeding by way of the filing of a patent application pursuant to the Patent Cooperation Treaty.
