Lululemon Athletica Inc., one of Vancouver’s most successful companies, is warning it may be forced to move its 1,200-employee head office outside the country because of problems with the federal government’s Temporary Foreign Worker Program, the Financial Post reports. The athletic apparel retailer — which earlier this year delivered a scathing written critique of the strict temporary foreign worker rules on hiring foreigners — wants the same kind of exemption Ottawa grants to universities, the film industry and Microsoft.
