Not abnormal in my experience. I cross the border into/out of British Columbia at the I-5 terminus serveral times a year and I've run into the same thing. Especially coming back into the US, the wait can easily reach 2 hours if you arrive at the wrong time of day. I don't know if the expansion on both sides of the border has opened yet or not. The added lanes should help reduce wait times however. I guess the expanision and update at the crossing is a result of the winter Olympics coming to town.
