Canada's resource-heavy main stock index was set to open lower on Monday, dragged down by falling commodity prices as the initial enthusiasm over a European Union deal to tackle its debt crisis faded.

FACTORS TO WATCH

* Canadian equity futures pointed to a lower open.

* U.S. stock index futures fell on lingering concerns a deal over economic integration in Europe will not be enough to keep the region's two-year sovereign debt crisis from spreading further. <.N>

* European shares remained lower around midday, although earlier losses were trimmed in thin trade, led by banks and insurers. <.EU>

COMMODITY PRICE MOVES

* The Thomson Reuters-Jefferies CRB index <.CRB>, a global commodities benchmark, fell 0.91 percent in early trade.

* Brent crude slipped below $108 per barrel as investors worried a European agreement on closer fiscal union might not be enough to contain the region's debt crisis or support growth.

* Gold hit three-week lows, after a rise in the dollar prompted enough selling to push the bullion price through a key level of support.

* Copper fell to its lowest in nearly two weeks on the view that industrial demand will weaken going into next year, with Europe's move towards deeper economic integration seen as insufficient to deal a final blow to the region's debt crisis.
