Three forest fires are continuing to burn at Base Gagetown with drifting smoke causing poor air quality in Oromocto and nearby Fredericton.
Training exercises on the sprawling military base reportedly ignited the fires in recent days which have not posed any threat to homes or structures.
A smoky sky over the New Brunswick capital city prompted public health officials to urge children, seniors and anyone with lung conditions to stay indoors.

San Francisco rarely suffers from hot weather which is why many residents are struggling to stay cool during a heat wave since most homes don’t have air conditioners.
The U.S. National Weather Service says the thermometer climbed to an all-time record-breaking 41.1 C (106 F) on 01 September and another record of 38.9 C (102 F) was set the following day.
Those sizzling highs are a far cry from the average of 21 C for the northern California city.
Numerous wildfires in the region have produced smoke and haze which has added to air quality concerns.
The heat has also stretched northward to Oregon, Washington State and British Columbia where temperatures could exceed 30 C on Vancouver Island.
Forest fires may be burning in Western Canada right now but smoke from those blazes has drifted thousands of kilometres east into New Brunswick.
Smoke was spotted in the Greater Moncton area on Monday and Tuesday although it was not heavy enough to prompt a warning from Environment Canada.
Meantime as shown above, dry conditions in British Columbia, Alberta and Saskatchewan have led to an extreme fire danger while it remains mainly low from Manitoba to Atlantic Canada.

Forest fire smoke envelops Yellowknife, NWT, 16 August 2014 (Twitter)
More than 50 forest fires are currently listed as out of control in the Northwest Territories during what has become a summer of fires.
The blazes have scorched more than three million hectares of land and have created drifting smoke which has meant poor air quality in numerous communities including the capital of Yellowknife.
Smoke from the fires has also been carried southeastward by the jet stream to Ontario, Quebec and the Northeastern United States keeping daytime highs lower than normal.
Commercial fishermen also say the fires have dramatically raised temperatures in rivers and streams leading to a scarcity of fish.
Winds are carrying smoke from forest fires in British Columbia, the Prairies and the Northwest Territories into Ontario and the Northeastern United States.
Forecasters say the smoke is even lowering temperatures by several degrees which has explained why Central Canada and the eastern Great Lakes region have been experiencing lower than average temperatures so far this summer.
The jet stream has been carrying the smoke but officials say it is moving at such a high altitude that air quality will likely not be affected in the region.
Environment Canada has issued an air quality advisory for Southeast New Brunswick.
Smoke from fires in Southeastern Quebec have penetrated into New Brunswick with the highest levels observed in the Southeast.
Poor air quality levels may persist until late on Wednesday when an approaching trough will give a southwest flow.
This should flush the smoke and improve conditions by Wednesday evening.

Environment Canada issued a special air quality statement for New Brunswick yesterday after smoke from forest fires in Quebec drifted into the province.
Satellite pictures showed a smoke plume extending from the Gaspé peninsula through central New Brunswick.
In Greater Moncton, the smoke descended close to the ground for most of the afternoon.
Westerly winds helped push the smoke over Nova Scotia and Prince Edward Island as well.
