If you do not have a disability please dont park in this spot

I have Primary Progressive Multiple Sclerosis and at this time I am still capable of driving. What upsets me the most is when i see fully capable drivers who do not have any disability park in the handicap spots so they can save time to go into a Tims or a convivence store just for a minute to buy lotto tickets or a coffee or what ever. I have been with our members who use walkers and powered wheelchairs waiting for a spot for these inconsiderate drivers to return to their vehicles. I have confronted these drivers, asked what their disability is other then being inconsiderate and ignorant. On a few occasions i have parked very close to their drivers door so they could not enter their vehicle. I wish their were enforcement on these illegal parking with heavy fines. These fines in turn will be used to make improvements on sidewalks, parking lots, accessible ramps for those who use acessibility vehicles to get around the city.
