The person that i think is the greatest Canadian is Ryan Reynolds.
Why? Well because he did a variety of Big Hollywood Movies, he bears the Canadian attribute of politeness and lastly, he did a heartwarming commercial for Air Canada.
My speech was pretty good because of the Eh joke at the beginning, good facts and good volume.
Some tips i would give people for public speaking would be to keep the flow good, look at the audience often, keep the volume at a level where everyone can hear, try to memorize the speech so you don’t have to look at your paper very much and finally, practice your speech so you don’t stutter on some words.
The second greatest Canadian i would pick would be Jim Carrey because of his sense of humor.
