A new report says changes to Alberta’s royalty regime will help make the province more competitive than its neighbours for conventional oil investment.

The paper out Monday from the University of Calgary School of Public Policy found that changes to the royalty system will bring the marginal effective tax and royalty rate for conventional oil projects in Alberta from 35 per cent to 26.7 per cent when it goes into effect Jan. 1.

Study authors Jack Mintz and Daria Crisan found the change will switch Alberta from having one of the highest to one of the lowest rates among its peers, including ahead of British Columbia and Saskatchewan.

The study, which pegged B.C.’s rate at 28.7 per cent and Saskatchewan at 32.6 per cent, did not take into account other regulatory and carbon policies that affect competitiveness.

In July, the Alberta government announced that companies could immediately apply for well projects under the new royalty regime that weren’t already planned.

The new royalty framework left oilsands royalties unchanged and simplified the system for conventional oil and gas wells.
