24 Hours. On summer solstice the earth is tilted toward the sun and it shines continuously at the north pole.

Alberta is not far enough north to have a day with 24 hours of sunlight -- that only occurs north of the Arctic Circle, in the three northern territories of Canada.
Between 0 and 24 hours per day. That depends on where you are and when you do your measurement. Far enough north of the polar circle there are weeks when the Sun never "sets" during the summer and when it never "rises" during the winter.At the equator on the equinox the theoretical sunshine duration is 12 hours.
Inyokern, California, which receives over 355 days of sunshine per year due to the strong rain shadow effect of the eastern sierras.
Usually around December 21st in the Northern Hemisphere and June 21st in the Southern Hemisphere.
North Dakota.. -40 -50 in the winter and above 100 in the summer
24 Hours of straight sunlight
In winter, you go south to get longer days. In summer, going north yields longer days.
The situation in the north pole is quite extreme, not like anything you are accustomed to. The Sun shines continuously during 6 months, then it is below the horizon for another 6 months.
The Sunshine Coast is just north of Brisbane, Australia. A flight between Melbourne and the Sunshine Coast takes about 2 hours and 18 minutes. Driving there would take about 19 hours.
That depends on where you are and which 6 month period you choose. At the north (or south) pole there will be roughly between zero sunshine and 6 months of sunshine (zero during the winter half year, and sunshine all the time during the summer half. That is theoretical sunshine, it takes a few days for the sun to rise and a few for the sun to set and if you factor into the situation that the atmosphere bends light then no six months will be entirely without sunshine (unless it is cloudy then which at the poles is a safe guess that it will be).

In the summer; yes, in the north.
The North pole
The astronomical start of summer is when the Sun is farthest north. It is a common misconception that the days get longer in the summer. They actually get shorter with each passing day.
The Sunshine Coast is north of Brisbane.
