A few places that advertise online quotes. Not sure how good these companies or their rates are, just know they exist.

The other "Alberta-ism" to be aware of........ here you have the option of just getting PLPD- Public Liability and Property Damage. Meaning if you get into a crash and it's your fault, the other party will be covered but your own repairs won't get done. Of course if the accident isn't your fault the other person's insurance covers your repairs.
This is handy if you have a car that is worth $2000, and getting only PLPD (aka declining comprehensive) will save you $1500, you might be better off. (Of course, depending on how confident you are in your driving abillities.)
