Exploration activity continued at a brisk pace in Canadian east coast offshore regions in 1984. Twenty-six wells were spudded, and drilling and/or evaluation continued on another 10 wells. Results were 4 oil wells, 7 gas wells, 1 oil and gas well, 10 dry wells, 1 well under a tight-hole status, 1 relief well, and 12 wells continuing drilling and/or evaluation at year end. Twenty-eight exploration agreements were negotiated, 17 of which were between the Canadian Oil and Gas Lands Administration (COGLA) and various oil and gas exploration companies and cover 9.6 million ha. with a commitment to 17 wells. Eleven exploration agreements were between the Canada-Nova Scotia Offshore Oil and Gas Board and the petroleum industry and cover 2.5 million ha. with a commitment to 14 we ls.

In Ontario (including Lake Erie), drilling activity declined slightly from 1983 with 200 wells drilled. Results were 54 gas wells, 26 oil wells, 80 dry holes, 12 suspended wells, and 28 wells classified as "other" (includes 9 stratigraphic tests, 9 natural-gas storage wells, 4 brine wells, 2 disposal wells, 2 water injection wells, 1 re-entry, and 1 LPG storage well). Oil and gas production in Ontario increased 6.5% and 19.3%, respectively, to 90,376 m³ of oil and 548,166 × 10³ m³ of gas.

In Quebec, 2 of 12 shallow wells drilled were completed as oil producers. Another well was drilled in Saint Flavien field, but it proved to be dry and was abandoned. Production in Saint Flavien field increased 166% to 11,841 × 10³ m³ of gas.
