The trucker convoy police have been warning drivers about is officially starting to arrive in Toronto, meaning you should probably take a peek at some local traffic cameras before hitting any highways right now.

The self-proclaimed "Freedom Convoy" is set to arrive at Parliament Hill on January 29 as part of a largescale protest against federal vaccine mandates.

The trucks themselves don't seem to be causing too much congestion yet. Some in the city are remarking that the traffic isn't bad, compared to what they're used to experiencing on the 401.

But it's getting busy out there — mostly on account of supporters who've arrived to stand along (and in some cases on) highway overpasses to cheer for the movement.

True patriot love.

Just a couple dozen protesters...
There are thousands here. And this is just one location: Vaughn, ON
The highway from Barrie to Toronto was packed. Flags everywhere. We will not lie down. We are Canada.#TruckerConvoy2022#TruckersForFreedom2022 @CBC @GlobalNational @CTVNews pic.twitter.com/KFjTlkEwCz

Volunteers were on hand with refreshments for truckers and whoever else showed up to scream about how much they hate everything.

Signs are plentiful throughout the crowd, many of them containing similar sentiments to the aforementioned chants.

There are also many Canadian flags being waved in support of the trucker convoy, as well as some flags that read "F*ck Trudeau."

Protest organizers have stressed that they are not necessarily anti-vaxxers — rather, they take up issue with government mandates that have forced truck drivers to get vaccinated in order to do their jobs.

"To our Fellow Canadians, the time for political over reach is over," reads a wildly-successful GoFundMe campaign set up for the cause.

"Our current government is implementing rules and mandates that are destroying the foundation of our businesses, industries and livelihoods. Canadians have been integral to the fabric of humanity in many ways that have shaped the planet."

Officials have nonetheless expressed worry about fringe groups, alt-right extremists and militant anti-lockdown types disrupting peaceful protest activities.

Ontario Provincial Police warned have been warning motorists since Wednesday of potential "significant traffic delays" on highways in and around Toronto.

"We understand that these convoys may affect traffic flow. There could be potential disruptions with that so, if you are a motorist in that area, plan ahead, expect delays starting on Thursday, and avoid areas if you are aware of these delays that are coming through," said OPP Sgt. Kerry Schmidt on Wednesday of the convoy.

"Protesters do have the right to peacefully protest, and for any participants involved in any types of protest, I know our provincial liaison teams are working diligently with the organizers to ensure public safety and traffic safety for everybody."

Traffic is delayed in some areas of the GTA right now on account of protest supporters clogging overpasses along Highways 401, 400, 427 and the QEW.

A "finale event" with someone singing the national anthem is planned for later this afternoon on the Sheppard Ave. overpass about Highway 400. 

"We do expect drivers to maintain a sense of movement and keeping the highways flowing for emergency vehicles and for other users of the highways," said Schmidt on Wednesday.

"Please be aware that officers will be monitoring and observing activities."
