Officials were forced to close the CN Tower due to falling ice from the structure.

Since the start of astronomical spring, the highest temperature in Greater Moncton has been 9.1 C and overnight lows have dropped to a near record low of -8.8 C.
So many are asking when is it ever going to warm up in New Brunswick?
The Maritimes has recently found itself on the north side of the prevailing jet stream which has allowed cold, Arctic air to sink south.
Environment Canada says the temperature should finally climb to at least 10 C by Friday.
Keep in mind, the first 20 C reading of the season was 12 April in 2017 while it was 21 April in 2016.

Weather warnings are covering Southern Ontario, Quebec and Atlantic Canada as a strong low pressure system brings strong winds, heavy rain, snow and freezing rain.
Sudbury picked up 29 cm of snow, four hours of freezing rain fell in Ottawa and Toronto Billy Bishop Airport had a peak wind gust of 98 km/h.
Southeast New Brunswick is the only part of the province not under a weather warning.
Northern New Brunswick could receive 30 cm of snow from this system while central and southwestern portions are under a rainfall warning with up to 35 mm possible.
Winter just won’t let go in Western Canada with Environment Canada noting the duration and intensity of the current cold snap hasn’t been felt since April 1970.
The polar vortex is to blame as the pool of Arctic air sinks south into the Prairies.
Daytime highs in southern Alberta are only climbing to -7 C with overnight lows in the -20’s C in Saskatchewan and -30’s C in Manitoba.
Forecasters say the bitter cold will hang around until the weekend.

Freezing fog in Summerside, PEI, 27 March 2018 (Twitter)
Residents of Southeast New Brunswick and Prince Edward Island woke up to freezing fog this morning.
This occurs when water droplets develop during fog and freeze instantly when temperatures are below freezing.
