"The onus is on the individual to satisfy the visa official that the criminal matter was settled," said Marima Wilson, a spokeswoman at Citizenship and Immigration Canada. The Canadian Border Services Agency has similar rules and can deny entry based on past criminal activity. "If charges, outside of Canada, were dismissed, the individual has to show us copies of court dispositions," spokeswoman Patricia Giolti said.
The academic now has an official Canadian piece of paper stapled to his passport. It says that the bearer should "provide all relevant court documents, i.e. certificates of dispositions, upon seeking entry to Canada in the future."

Sealed or not sealed if our Canadian Border Services Agency officers can't get full access or the information is not fully shared as to prior arrests and convictions then no one should be let into Canada, American or not. The Americans do the same to Canadians so why should it be any different for them. Also no Politician should be able to over rule that either. These situations threatens Canada's security.
