Currently, you are only able to respond and edit preset text messages on the MyFord Touch system. Send me a PM with your name, VIN, mileage, and phone number if you would like me to document your feedback for your type of SYNC system.
Although SYNC Services are not available in Canada, you do still have the text message option available. To see a list of Canadian carriers, click the link in the upper right hand corner of this chart: SYNC and Phone Compatibility | SYNC Support | SYNC & SYNC with MyFord | Ford.com
