A French curve is a template made out of plastic, metal or wood composed of many different curves. It is used in manual drafting to get a smooth curve of varying radii.

The image on the right shows the three most common French curves; this set is also known as the Burmester set. The one in the far left corner is most commonly used for hyperbolas; the smaller one in the far right corner is suited for ellipses. The large one below is used most for parabolas. This information comes from Docu+Design Daube's excellent page on drawing tools.
Modern computer CAD drafting systems use vector based graphics to achieve a precise radius, so no template is required.

These curves will be set in a world that represents all communities in Canada: from a 100% French speaking community (one Quebecois village for example) to a 100% English community (one British Colombia village for example).
We consider that English and French have the same degree of difficulty for an immigrant whose mother tongue is not French neither English.
Indeed, as long as those curves are asymmetrical, immigrants will have a tendency to learn English, and French speaking people to speak English (however in a few proportion, considering the inertia of switching from a language to another).
