Is ageism a big issue in Canada?

The fact that a phenomenon called ‘ageism’ exists has a lot to say. I guess people believe that those with grey hair are from outer space. Ageing is a normal part of life; most people believe ageing or being old is a bad thing, and some people never think of growing older; it’s like it only happens in movies!
Yes, ageism exists, and it is a big issue. If there weren’t any laws against age discrimination, most people after 50 or so would be unemployed. And it’s not just the workplace; you can see it everywhere. There are anti-aging face creams available. Why? Is ageing a terrible thing? Is it like a virus, and the cream is anti-virus?
