A group from Quebec did not have a good trip to Wasaga Beach this weekend, after Ontario police stopped them for allegedly smoking marijuana and later charged one of them with driving at more than twice the legal speed limit.

Ontario Provincial Police say the foursome was spotted by officers on foot patrol at around 3 p.m. on Friday along the main stretch of Lake Huron's Wasaga Beach, about 130 kilometres north of Toronto.

Officers say the group was observed smoking marijuana on the beach; a subsequent search uncovered more of the drug, police alleged on Sunday.

The four people, all from Quebec, were charged with possession of a controlled substance and later released from custody pending an appearance in a Collingwood, Ont., court.

Huronia West OPP said the group's rough weekend didn't end there.

A highway patrol officer stopped a vehicle leaving the area while travelling 104 kilometres an hour in a posted 50 km/h zone.

Provincial police impounded the vehicle for seven days and charged the driver with stunt driving.

"The same set of rules applies here that apply every other place. Just because it is Wasaga Beach doesn't mean the rules take a holiday," OPP Const. Tim Garland told ctvtoronto.ca on Sunday.

"On the weekend we get a large influx of people who seem to check theirs brains at the door."

Huronia West OPP were also kept busy this weekend laying a string of impaired driving charges against visitors to the cottage hot spot.

Six people were charged with impaired driving over a 12-hour period Saturday night and Sunday morning.

A 21-year-old man was charged with driving under the influence of alcohol after police responded to a collision at 8 p.m. on Saturday. Less than 30 minutes later a 44-year-old man drove his pickup truck into a ditch and struck a tree.

Four others were also arrested over the course of the night and morning, including a 17-year-old male who rolled his truck into a ditch while trying to evade police cruisers.
