Practical guidance
Avoid cross-border transport of cannabis products. Do not assume informal tolerance equals legality.
Law Enforcement
Like Toronto, Oshawa officers were thought to have bigger priorities. The old rule of thumb was that under 3.5 g might get waved through, with confiscation or a ticket more likely above that. Being polite and honest helped.
Rules on adult personal possession have changed since this account. See Marijuana Laws.
Where to Buy Marijuana
A university and a college sharing a campus. Enough said.

Types of Marijuana
Purple Haze was rated excellent. Creeper seemed to do very little for 10–15 minutes, then you were blitzed. Blueberry tasted like blueberries. The flower sold as “Chinese weed” was considered weak. “B.C. Bud” and “Cali Weed” were names for bud said to come from British Columbia or California.
