Good ad by the Saskatchewan Party although it doesn’t do well on the whole accuracy meter.
Young people are still leaving Saskatchewan but it is immigration that is keeping the provinces population up. Also, the government in power during the time that Wall is speaking of, was not a NDP government, it was the Grant Devine administration in which Brad Wall worked for as a staffer and later chief of staff. As far as people leaving the province during that time, the population in Saskatchewan actually grew by 40,000 people.
Political ads never let the facts get in the way of a good ad.
