If you want to stay away from streets altogether, there are a number of trails you can consider. There is the Martin Goodman Trail, Moore Park Ravine, Tommy Thompson Park, Don River to the East, the Humber trail to the West, and the Waterfront system along the shores of Lake Ontario.
Medicaid is a public medical welfare program for the poor. It is funded through federal and state taxes. 'Obamacare' is a market for purchasing private insurance. It is designed for people with income that makes them ineligible for Medicaid and Medicare. For people meeting certain income limits and unable to purchase qualifying insurance through an employer, a variable subsidy is paid toward the private insurance premium.
Both are government medical insurance programs. The difference is the eligibility requirements for the two programs. Medicaid is for disabled or elderly (age 65 and up) people with very limited assets and income. Medicare requires that someone have paid medicare premiums through their employers or self employment income.
