I welcome the chance to cover this, because it is a key preoccupation right now across the country and the industry. We hear that loud and clear every time we engage with those players to make sure that Canada is a clean producer but also cost-competitive. I mentioned the extraordinary degree of innovation but also entrepreneurial spirit in the country.
As we've seen in history in so many ways, a crisis will kind of force humans to come up with extraordinary solutions. I think we've seen this happen again and again in Canada's oil and gas sector. Most recently, with the price downturn, we've seen those companies and individuals looking at all sorts of innovative ways to reduce their costs of operation. They're changing some of the technologies they use, looking at their use of the labour force, looking at reducing the input of productions in their activities, and trying to consolidate in some cases the industry players in their domains. All of this has led to very significant cost reductions, driven by those firms. We are in regular discussions with all the major oil and gas producers in Canada. It's truly impressive what they've managed to do to reduce their costs of operation at the firm level.
From a country's perspective, as I mentioned earlier, the government featured this prominently in the 2018 fiscal update. The principal announcement in that update was around competitiveness and bringing about measures in our tax system to accelerate the capital cost allowance of some of the large investments. This was seen also in the context of the competitive landscape, especially in North America, where south of the border some major corporate tax announcements were made and the government came up with fairly sizable corporate tax measures to the tune of $5 billion a year. It was certainly not trivial in terms of changing that landscape.
