Really random question... Sorry not sure if this is the correct thread.

There is a 2013 database of Canadian mortgage brokers that is up to date and current here:

I'm wondering if there is any way to access the database history from 1 year ago. Basically, I'm trying to figure out which mortgage brokers have retired (e.g. If they were listed in 2012 but NOT in 2013)

Is there any way to do this? Any tool?

Thanks for any advice!
