The ICBC changes are a mixed bag. The real risk is accepting a quick settlement and assuming your injury is minor before knowing whether or not that actually is the case. If the condition persists and continues to have an impact on your life, you will no longer meet the definition. So for many, the key will be to not settling too soon - and to wait until their injuries are fully resolved before doing so. The other big thing is to know that many of the changes do not apply to collisions that happened before April 1, 2019 - so if your crash was before then, you are still entitled to pursue a claim through the courts.
Positives: more money for rehabilitation expenses (no more user fees), more money for lost wages (note, this is one reason to renew even if your policy isn't yet up as the lost wages amounts go from $300 per week to $740 per week).
Negative: No right to claim for expenses that exceed the fee limits imposed by ICBC (does not apply to crashes before April 1, 2019), no right to subrogate for costs borne by your extended health care plan, an arbitrary and unfair cap to pain and suffering for injuries that are deemed "minor", being forced to the CRT forum for claims less than $50,000.
As far as more severe injuries go - the old system still applies.
The way in which these changes were designed and implemented leaves much to be desired - and there is a conflict of interest when the minister for ICBC is also the AG as the AG is there to safeguard the legal system and the civil rights of people, while the changes implemented directly infringe on those rights.
