Alberta is taking steps to get a better handle on immunization records for children.
The government is bringing in legislation to cross-match school-age students with their immunization records to make sure no on is being missed.
Health Minister Sarah Hoffman says it will also help officials move faster in the event of an outbreak.
Officials say immunization rates for young children are in the 80% range for measles, mumps, and rubella but need to be higher.
Parents of students with missing immunization records would be asked to provide the information, get the immunization, or sign a form saying they did not wish to immunize their children.
Hoffman says the government does not want to make vaccinations mandatory.
Children who do not get immunized can be directed to stay home if certain highly contagious vaccine-preventable diseases break out at their schools.
