IIRC car trips still represent something like 50% of total trips nationwide, even in the netherlands. Definitely not 3%. I mean the Netherlands has the largest and densest freeway network in europe (and they regularly expand it!). Canada sees about 85% IIRC. Also - a lot of that difference is not from cycling, but from walking, which sees significantly higher modal shares across most of europe than in north america for a variety of reasons.. Cycling modal share in the Netherlands is "only" around 25% compared to 1-2% in Canada, and walking is at around 20% vs. 4-5% in Canada.
The Netherlands also has 513 cars per 1,000 people vs. 677 for Canada, so only about 25% fewer cars overall. People tend to overstate how little dutch people drive - definitely a lot less than Canadians, but cars are still a major factor in peoples lives. Most households own a car and regularly use it, with car commuters outnumbering cycling commuters at over a 2:1 ratio.
What is a lot less common I think is 2-car households.
