Skate boarders in Calgary may use bike trails and parks dedicated to them, but are prohibited from sidewalks.

Bicycle use of sidewalks is prohibited, and will be subject to fine. They are a danger to all pedestrians.

Under the Vehicle Code here, if there is no bike lane, bikers must take their chances on the roadway. They are prohibited on city freeways if there is no lane provision- cars and trucks are traveling at 60 mph or more, and pedal bikers are easy prey.

Highways have a paved space to the right of the traffic lanes, used for emergency stops by cars, but usually are clear and may be used by bikers.

I believe the ticket for sidewalk biking is $60 here, but I haven't checked.
