If you don't live on the west side of Vancouver Island there is likely nothing to worry about. Vancouver Island is a giant wall that protects the coast. They have apparently done soil studies in Vancouver and can't find any evidence of historical tsunamis. OTOH, the lack of warning should be a serious concern for those people who do live in tsunami central.
I used to believe that about Vancouver Island protecting Metro Van but came to find out a little while ago that it's not true.
In fact, the warnings today actually included Vancouver.
