Canadian inventors have patented more than one million inventions. Let's take a look at some of the top inventions brought to us by those from Canada, including natural-born citizens, residents, companies, or organizations based there. According to Canadian author Roy Mayer in his book "Inventing Canada: 100 Years of Innovation": 

"Our innovators have given novelty, variety, and color to our lives with their great practical gifts, and the world would be an exceedingly boring and grey place without their vitality."

Some of the following inventions were funded by the National Research Council of Canada, which has been an important factor in innovation and technological advancement in the country.
