Final answer:
All provinces, including Ontario, Quebec, British Columbia, and Alberta, have tax-based healthcare funding under Canada's universal healthcare system known as Medicare, which is publicly funded but delivers care through private providers.
Step-by-step explanation:
All provinces in Canada have tax-based healthcare funding, including Ontario, Quebec, British Columbia, and Alberta. In Canada, healthcare is publicly funded through taxation and is administered by the provincial and territorial governments. This system, known as Medicare, is in line with the Canada Health Act of 1970 that mandates the provision of universal healthcare to all Canadian residents. It is important to note that while the funding for healthcare is public, the care is delivered by private providers, distinguishing Canada's universal healthcare model from socialized medicine systems.
