I'll start.
Syncrude has a very strong relationship with the Alberta Building Trades Council, and on the rare occasions when we have peak workforce needs that exceed the Canadian capacity, we work with the building trades for them to identify, through the American building trades or the Irish or others, a supply of workers who come in through the building trades council. They're certified by the trade union. They pay dues and then they are brought to our site under the temporary foreign worker program in partnership with the building trades. We as a company can be confident that both the Alberta building trades as well as the broader Canadian building trades have exhausted all potential supply before we do that.
