A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
First of all, open System Preferences>Keyboard>Input Sources and make sure you have a French Canadian keyboard. Click the plus sign to install one if you don't.
Then activate the French Input at the right end of the OS X menu, so you see a Canadian flag. PowerPoint may switch languages to Canadian French automatically when you do this.
If not, it's because your PowerPoint template was formatted in a different language. While you can activate French by clicking on each text placeholder and using Tools>Language to change it to French, it's much quicker to set the default language to French temporarily. Make sure no placeholders are selected, choose Tools>Language>French (Canada) and click on the Default button. PowerPoint will ask whether you want to switch, choose Yes.
