By Reuters Staff 1 Min Read (Reuters) - Canada’s Secure Energy Services Inc said on Tuesday it would buy waste management services firm Tervita Corp in an all-stock deal valued at C$478 million ($379.5 million), the latest consolidation in the country’s oil sector. The deal, which will value the combined company at around C$2.3 billion, comes as oil and gas companies seek to benefit from a recent run-up in crude oil prices while keeping a tight leash on costs. Secure, which operates a network of crude processing and storage plants, oil and water pipeline and crude-by-rail terminals, said it will pay 1.2757 of its shares for each Tervita share held.
