If producers are producing fewer films because more people are copying them, this must be having direct repercussions on the artists who make these films. They have less incentive to make films, because once released, they are copied and viewed elsewhere. You tell me the figure is 3.6%. Your association must have some power to attempt to put an end to piracy. Otherwise, you will also be forced to cut jobs within your own field.
Earlier you said that the relative value of the Canadian dollar has an impact on this phenomenon, but so does immigration. When an American production is being filmed in Canada, there is no requirement to have a certain percentage of Canadians hired on the film. People from all over, be it the United States or elsewhere, can be asked to come here and play minor roles. There is nothing that says that when any film is produced in our country, a percentage of Canadian workers must be hired.
