Thank you, Brian, and good morning. I am pleased to discuss our first quarter operating results, highlighted by the performance of our refining assets that clearly demonstrated the benefit of our integrated strategy. We continue to execute on our oil growth strategy, increasing overall oil production by 15% when compared to the first quarter of 2012. We also continued to progress development across all phases of our oil sands construction projects. Our oil sands growth plans remain on track at our 2 producing properties. At Christina Lake phase E, construction is about 90% complete and we anticipate first oil in the third quarter of this year. We expect performance of phase E to be similar to last 2 phases at Christina Lake, ramping up to a design capacity in 6 to 9 months. Procurement, plant construction and major equipment fabrication continue for phase F at Christina Lake, and front-end engineering and design is underway for phase G. At Foster Creek, construction of the phase F plant is 73% complete, and we anticipate first oil in the third quarter of 2014. Phase F is critical as it includes prebuild for the subsequent expansions at phases G and H. In addition to our current expansions, we filed regulatory applications and environmental impact assessments for Foster Creek phase J and Christina Lake phase H. Both of these expansions will add 50,000 barrels per day of gross capacity. Foster Creek production averaged approximately 112,000 barrels per day gross in the first quarter. This was down 2% from the 114,000 barrels per day a year ago, and about 5% below the 118,000 barrels per day in the fourth quarter of 2012. This was primarily due to higher-than-expected downtime on some producing wells. Including wedge wells, we had 229 producing wells at Foster Creek. Foster Creek normally has 3% to 4% of its wells down at any one given time. But during Q1, we ran slightly higher at about 7%. We are currently working to reduce that back to normal levels. We also plan on drilling 16 producing wells in 2013 in addition to bringing on 11 new wedge wells. We expect Foster Creek gross production to range between 110,000 barrels per day and 120,000 barrels a day for the remainder of the year, and we expect to be towards a higher end of this range in the third quarter. We have also moved to blowdown and co-injection on 3 of our pads at Foster Creek, our first SAGD pads to go on to blowdown. As we reduced steam injection and co-inject methane, we expect that well productivity in those pads will naturally decline. The steam is then reallocated to new pads and over time, drives new production. We have decided to defer our previously-planned second quarter turnaround at Foster Creek in order to optimize the work required. Exact timing is yet to be determined and the impact of the turnaround is still included in our production guidance for 2013. We are well-positioned to have another successful year at Christina Lake. In the first quarter, we've demonstrated facility capacity and delivered another strong ramp-up in production from phase D. We are working to optimize the facilities and maintain a steady production rate going into our planned turnaround in the second quarter. We expect volumes will be impacted by approximately 5,000 barrels per day net to the quarter. Per barrel operating cost at Foster Creek and Christina Lake trended higher from the fourth quarter as a result of higher fuel costs and workover costs, and also slightly associated with increase in staffing costs for future expansions. We continue to place a strategic focus on reducing our operating costs on the way forward. As production ramps up in the second half of 2013, we expect operating cost per barrel to decline. As always, we continue to look for ways to reduce our operating costs. At Narrows Lake, we are progressing site preparation, detailed engineering and procurement. Orders have been placed for most of the major equipment. We will commence construction of the phase A plant in the third quarter. At Pelican Lake, we anticipate more meaningful production gains to occur later this year based on the timing of the response from new producer wells drilled in 2011 and 2012. The production response from our infield and polymer flood programs has been a little slower than we expected for some of our pads. And as a result, we have elected to reduce discretionary spending this year by approximately $80 million. This reduction relates to deferral of facility construction and a reduction in our rig count from 4 to 2 rigs later on this year. We expect to exit 2013 between 200 -- sorry, between 27,000 and 29,000 barrels per day. Operating cost per barrel at Pelican Lake are trending towards the higher end of guidance for the year, primarily the result of lower-than-expected production, higher workovers, chemical and workforce costs. We continue to move our engine -- sorry, our 2 emerging oil sands plays through the regulatory Q and progress work on the pilot projects at Telephone Lake and Grand Rapids. The dewatering pilot at Telephone Lake is running very well and results are in line with our expectations. And at Grand Rapids, our second well pair pilot began producing in February and continues to ramp up. We plan to give a more thorough update at Investor Day in June when more data is available on these 2 pilots. Turning to light and medium oil developments, we added approximately 2,400 barrels per day from southern Alberta assets compared with the first quarter of 2012. This is the result of our previous reallocation of capital from natural gas to the oil side and an increased focus in Alberta where we maintain an advantage on our feed properties. So far in 2013, we are seeing little in the way of inflation. Given the recent discounting of heavy oil prices, we are finding the availability and quality of services at competitive rates improving. We remain focused on hitting our operational and safety targets for the year and believe we are off to a great start for 2013. I will now pass the call on to Don Swystun to talk about our refining business.
