A Farm Credit Canada economist says the UK's exit from the European Union will have short and long-term impacts on Canadian agri-food markets.

JP Gervais says the exit will create instability and volatility in financial markets.

He says that usually means a stronger U-S dollar as investors look for a safe haven.

While a stronger US dollar usually means weaker agricultural commodity prices, Gervais doesn't think the impact in this case will be too significant.

Infact, he says a lower Canadian dollar could mean more attractive prices - in the short term - for commodities priced in US dollars that Canadian producers sell.
