Let's see... do you have a ScanGauge? If so, you can set it to kilometers for more accurate speed reading
(otherwise: 50 kph = 30 mph, 80 kph= 50 mph, 100 kph = 60 mph (to one significant digit. 100 is really 62 mph)).
Your Sprinter has a dual-gauge, but it's helpful to know the numbers. Also for estimating distances (100 km = 60 miles)
For fueling, if you just think of liters as quarts (so 4 to a US gallon) you're "close enough".
Verify that your auto liability insurance is valid for Canada: call your agent/company and get the (free) "Canada card"
(that's an ancient piece of advice, but check it out anyway)

You will need proper documentation for your pet (showing vaccinations).
Dogs 8 months and older and cats that are at least 3 months old need signed and dated certificates* from a veterinarian verifying that they have been vaccinated against rabies within the last three years.
The certificate also must:
be written in English or French;
be issued and signed by a licensed veterinarian;
identify the animal (breed, sex, color, and weight);
state that the animal is vaccinated against rabies;
indicate the date of vaccination;
indicate the trade name and the serial number of the licensed vaccine; and
specify the duration of immunity (otherwise, it will be considered valid for one year from the date of vaccination).

Don't try to bring firearms into Canada unless you do a LOT of reading up on the subject.
(question 4 of

If any of your passengers have a criminal record, they may be refused entry.
Don't bring fresh fruit (and meats are usually prohibited, too).
I've driven through and across Canada many times. For those of us near the border, it's always been a fairly casual process.
The usual border questions are: How long are you going to be in Canada? Any guns? Any fruit? (i forget if they add "or vegetables") Any gifts for people in Canada? Have a nice day.
I've never had a pooch with me, so i can't say what extra questions that invokes.
It never hurts to pre-warn your credit (and debit) card companies that you'll be travelling.

p.s. if you're driving north from the Seattle area, there are multiple border-crossing options.
The biggest is the I-5 "Peace Arch" crossing in Blaine, but it can take the longest.
Nearby is the "truck crossing", (exit 275 from I-5, to WA 543 which becomes BC 15) ... it can be quicker.
There's an illuminated sign on I-5 with estimated wait times, and Vancouver's AM 1130 includes wait-times with their every-ten-minutes traffic reports. Likewise the Washington DOT phone app has border crossing times.
If you're not planning to actually hit the city of Vancouver, there's also WA 539 and WA 9. The AM 1130 uses the Canadian side's towns' names (Abbotsford and Sumas) for those two.
For even more fun, you can take a ferry from Port Angeles on Washington's Olympic Peninsula to Victoria on Vancouver Island, and then Canadian ferries to reach the mainland.
