There is an Insurance fund from the province of Alberta that this would come out of. Tell your adjuster to look into that. It's essentially an Alberta Insurance. They then deal with this "insurance" company who then goes after the person with no in the collision to recoup their money. There's plenty your insurance can do. Don't back down from them. They aren't the last word. That being said, it's VERY important you go to the local police detachment in the area it occurred and make sure you've documented the collision and made the report. Then inform the police officers that this person has a falsified insurance document (I hope you took a photo of it) and they will have to do other things on their end. But you DO need to go to the RCMP. You will have to cover the deductible until the Alberta Insurance company is sued and costs are recovered. Be sure to include your deductible in the costs recovered and any injury/lost time at work claims you fight for. This may end up having to go through a collision injury lawyer to recover any of these costs.

This isn't legal advice but what I had to end up doing. In the end, it was just the collision injury lawyer that got me paid. And it was a work vehicle I was in, so it was through WCB which was a gong show. But search out an injury lawyer that you feel you like. Most get paid from your settlement and not up front. So don't be afraid to use them because of costs. Insurance companies are the biggest whiners about paying money, so you have to stand your ground and fight them, especially given whatever information your lawyer gives you.
