Yes. I think no Icebreaker would keep this lake open. The ice freezes several feet thick-The patch of ice in the foreground (the harbour entry during warmer months) is part of what we call an Ice Road... When it gets cold enough and the water is frozen quite solid they send out plow trucks to plow the snow to make roads right over the lake. They are very slippery, and very dangerous, but also the ONLY roads to the whole northern half of our province (Manitoba). Many northern communities and aboriginal reseves rely on these ice roads- built over tundra, muskeg, lakes and rivers, to get all the supplies in they will need for the whole year. The roads are usable for 7-8 weeks each year and see huge numbers of transport trucks during that time. You have to have quite the nerve to drive them, as apparently you can feel the ice sagging and moving and hear the cracking and groaning of the ice as you drive those rigs over. Drivers wear layered clothes, full immersion suits and often travel in convoys for safety seperated by a few hundred meters between trucks. This particular Ice Road only went a few hundred meters out, just past the Gimli Breakwater to a popular Ice Fishing spot. :-)
