California is part of the Drivers License Compact (DLC) which requires other member states of this agreement report to the CA Department of Motor Vehicles moving violation convictions. While Canada is not part of the DLC, California may have similar reciprocal agreement with parts of Canada as well.

There is Provision 13363 of the California Vehicle Code which states that the DMV can suspend or revoke the license upon notice of the conviction of a person in a state, territory, District of Columbia, Puerto Rico or the Dominion of Canada of an offense which if had been committed in state, would have been grounds for suspension or revocation of the privilege to operate a motor vehicle.

CA Vehicle Code sections 23521 (minors and out of state offense) and 23626 (Effect of Conviction in another jurisdiction) also mention penalties for those convicted of an offense in the Dominion of Canada.

We found the Alberta Reciprocal Enforcement of Judgments Act which on it lists all other Canadian provinces and territories as well as Australia, and the following States in the US - Washington, Idaho and Montana. This reciprocal agreement may or may not extend to driving infractions in these areas.

We did not find information regarding any type of specific reciprocal agreement between Alberta, Canada and California however we would recommend to check with the California Department of Motor Vehicles to find out what provinces of CA there are agreements with concerning the sharing of traffic violations and convictions.

To fight / contest the ticket or to not pay the traffic ticket you received in Alberta is a personal choice. If you choose to not pay the ticket or take care of it in any other legal manner then likely the Alberta will send you a summons for a failure to appear and if you do return to this Canadian Province in the future and are found to have an outstanding citation there will likely be severe penalties. A traffic lawyer for this area of Alberta, Canada may be able to advise you on what your options are regarding the ticket as a driver from out of the country.
