A few:
-Pharmacare (prescription drugs) is not covered. Canada is the only developed country with a Healthcare system that does not cover drugs for everyone.
-Drugs in Canada are also one of the highest priced. Covering drugs in the healthcare system would fix this.
-Dental care is not covered.
-Vision care is not covered.
-Due to underfunding there are long wait times for particular procedures, and whole areas like mental healthcare.
Also there is a shortage of doctors in many areas of the country, so many Canadians lack a family doctor.
Also:
While Abortion has been legal for some time, access is not guaranteed in Canada.
Outside of major urban areas, its all but impossible to access a health clinic that offers abortion services in much of the country.
And its only last year that the province of Prince Edward Island even allowed abortions to be performed.
