North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
Canada ↗Visa-exempt travellers flying to or through Canada usually need an eTA; check your passport on the official Government of Canada site (canada.ca) and apply only there.
Canada ↗A Parks Canada pass is needed to stop in national parks such as Banff and Jasper; some spots (for example Moraine Lake) are reached only by shuttle or tour, so book ahead.
Canada ↗Keep well away from bears, elk and moose; carry bear spray on Rockies trails and follow trail closures.

Ontario is bigger than France and Spain together, but almost everything a first-time visitor wants sits in the southern corridor: Toronto, Ottawa, Niagara Falls and the lakes within two hours of the 401. Pick one or two bases, rent a car only for cottage country or the north, and skip the long hauls unless you have a week or more.

Night sequences

4 nights: Toronto 3 + Niagara Falls 1 (car for the wine route)
6 nights: Toronto 3 + Ottawa 2 + Niagara Falls 1, train between the cities
8 nights: Toronto 3 + Algonquin or Muskoka 2 + Ottawa 3

Toronto + Ottawa + Niagara Falls + Algonquin in 4 days is mostly highway.
Winter driving north of Barrie needs winter tyres and a flexible plan; Highway 11 and 17 can close in storms.
Black flies and mosquitoes peak late May to early July in the north; bring repellent.

Montréal (YUL)	Ottawa or Toronto	VIA Rail from Dorval, or road	~2 h to Ottawa, ~5 h 30 to Toronto by train	Useful when Ottawa or Toronto flights are full or expensive.
New York City	Toronto	Amtrak Maple Leaf, or bus	~12 h	Train crosses at Niagara Falls; buses run overnight and are usually cheaper.

Regional passes

Verdict first

GO Transit day pass

check

Can pay off for a weekend of GTA and Niagara travel; weekend passes are the usual value play.

Presto card

buy

Tap fare card for GO trains and buses and most municipal transit in the GTA and Ottawa; a contactless credit card works on many readers now.

VIA Rail

check

No nationwide rail pass worth buying for Ontario alone; fares are dynamic, so book 2–4 weeks ahead.

Parks Canada Discovery Pass

skip

Ontario's main parks are provincial, not federal; the pass rarely pays here.
