While compatibility surveys may be finding their way onto many dating sites, e Harmony is known for their matchmaking savvy, running their own relationship research facility, e Harmony Labs, as well as e Harmony advice.
When users sign up for an account, they are presented with a detailed survey that outlines their personality traits, needs, and wants.
An added bonus is the astrological match feature, which determines your compatibility based on your sun sign (if that’s important to you).
As an American website with an international crowd, it might be a little harder to locate Canadian locals, but the profile-driven site makes up for that wider target audience.
The downside is the slightly outdated user interface, but since the site is targeted at seniors directly, the crowd is on the older side, which might be just what you’re looking for.
