Scandinavian /UK travel(US waiver)

Hello All

I am a Canadian citizen with valid US waiver because of my history in US. I was charged with violation for working off campus when I was a student back in states. My waiver is due in May and I have already applied for an extension. I have no record in Canada.

I need to travel for business to Scandinavian /UK . Has anyone traveled to Scandinavian /UK countries while on us waiver ? I am planning to fly out from Pearson if waiver doesn't come through before time. Any comments or experiences on traveling to Scandinavian /UK with waiver will be highly appreciated. Thanks
