I just glanced through the criminal code but, couldn't find an exact thing which will equal to your case. On surface it looks like 2 summary offences. I hope it is just speeding tickets and no harm done to people or property.
One offence will not affect your admissibility. My concern is as it is 2 times. However, if you were not under influence of any drug, alcohol it could't be an issue.
If it is 2 summary offences you will come under an inadmissibility factor. If you have time, just go through what is the punishment for speeding under Canadian law. Then can decide what to do next. If it is not a criminal offence, it should be ok.

Don't get panic.
