Connors Bros. Clover Leaf Seafoods Company is one of Canada's oldest companies. We've operated a sardine and herring cannery in Blacks Harbour since the 1880s. We currently employ about 600 people at our Blacks Harbour facility, and are one of the main employers in Charlotte County, New Brunswick. In addition, we operate an international sales and marketing office in Saint John, New Brunswick, which sells seafood through our own brands in over 50 markets around the world. Our Canadian head office is in Markham, Ontario. We're responsible for just under half of all canned seafood sales in Canada just through our own brands, Clover Leaf and Brunswick. In addition, we have a sushi-quality frozen seafood food service business through our affiliated Anova unit. We are affiliated with Bumble Bee Seafoods in the United States, with its headquarters in San Diego, California, and we are owned by Lion Capital, a U.K.-headquartered private equity firm.
I'll skip to the main concerns that we have with respect to the TPP. Connors Bros. Clover Leaf Seafoods Company has several concerns related to the proposed TPP FTA with respect to our Canadian operations. The current herring resource constraints from Canada mean that there are no market outlet advantages gained by the TPP for our company with production from our Blacks Harbour canning facility. We currently have to procure finished goods mainly from Europe to meet our overall corporate requirements for branded sales in Canada, the United States, and other international markets. Labour cost differentials among many of the TPP parties such as Mexico, Malaysia, Peru, and Vietnam put our continued production at risk in New Brunswick. Our labour standards and obligations are also disproportionately higher than many competitive sources supplied by TPP partners, which further affects our competitiveness.
The simple elimination of tariffs, without addressing other regulatory issues affecting our operations in Blacks Harbour, may be a threat to the competitiveness of that operation. This results from operating requirements imposed on Blacks Harbour for regulatory compliance under a number of Canadian regulatory bodies, including CFIA and DFO. One example is with respect to import restrictions on raw material being processed in Blacks Harbour. We are currently unable to import herring from Sweden to offset our shortage of locally available fish. The concern is that this may be a vector for marine diseases being spread through the Bay of Fundy region. To our knowledge, several TPP parties where canned sardine products are produced are not similarly constrained and freely import and process fish harvested from outside their territorial waters.
We are unclear on what implications the TPP will have with respect to NAFTA. We currently export canned sardines from Canada to the United States and Mexico, and our affiliated company, Bumble Bee Seafoods, has major concerns about the TPP with respect to its operations and its market position in the U.S. market. Bumble Bee Seafoods is the largest branded canned seafood company in the U.S. market.
Those are the essential concerns that we have.
