Scoozame -- in many provinces including Ontario and BC,  there is legally no minimum age for your daughter to provide her own consent. 
It is your call only until your daughter -- at any age -- disagrees and shows she has the capacity to provide her own consent. This could be 14 or even less in some situations. In some school districts guidelines are provided: for example, in Peel region, "written parental/legal guardian consent is required for students under 14 years of age" -- https://www.peelregion.ca/health/shp/2008/shrg-topics/immunization/
