Do not worry, I have tons of speeding and various other tickets. I once had 6 points levied on my licence coz I had had a couple of beers and hit a bloody fox, although I was well under the legal limit they blamed my lack of judgement on my drinking ( ridiculous, I know. go on you can laugh!!)My history of traffic offences were also considered and my licence was suspended for 1 year.
Within that one year they caught me driving again (it was really cold and I really needed milk for me coffee) and got suspended from driving for another 6 months

.
I not only got an extension of my UK visa where they do a through criminal check as well but have also received a request for my
passport from the Canada guys.
Don't worry, if it is just as what you have mentioned, you will be fine.
There is not a single person out there who has not broken any traffic laws, some are lucky not to get caught, and some others are like me.(One wrong step and a copper miraculously appears right in front of me)
I am sure the Canadian authorities are aware of this.
