* February WCS at $33/bbl under WTI
* February synthetic $1.75/bbl over WTI
* Kearl oil sands output seen still a few weeks away
CALGARY, Alberta, Jan 2 Canadian heavy crude prices strengthened on Wednesday as production from Imperial Oil Ltd's new C$10.9 billion ($11 billion) oil sands project appeared to be still a few weeks away.
Western Canada Select heavy blend for February delivery last sold for $33 a barrel under benchmark West Texas Intermediate, compared with $33.25 under WTI on Monday, according to Shorcan Energy Brokers.
Last month, WCS had at times sold for around $40 under WTI as traders weighed the impending start-up of Imperial's 110,000 barrel-a-day Kearl oil sands project against a backdrop of already-tight pipeline export capacity.
Imperial said on Wednesday that output from the venture was possible in the coming weeks, after a delay from the initial target of the end of 2012.
Meanwhile, light synthetic crude for February was last quoted at $1.75 a barrel over WTI, compared with 50 cents a barrel under on Monday.
