There's a serious problem of a widespread lack of access to family doctors, ER overcrowding, and extremely long EMT response times.

At least, there is in BC. Each province manages health care as they see fit.

The problem here is mostly the lack of available nurses and doctors, who have to pull insane shifts to compensate. Hospitals are also very concentrated in urban areas. Canada has 30% less nurses per capita than the US.

No.

You obviously haven't been to a hospital in Toronto in the last 10 years. Go visit St Joes, you walk in and take a ticket like you're at the butchers. The ticket is to get in line for administration. After administration you wait 12 hours for someone to see you. Just peek through the emerg doors and you see people in hallways lying in beds. The Canadian medical system is shit compared to the US medical system.
